An odd Tuesday night has turned into a busy Wednesday afternoon here at Nationals Park.

After some misplays in the field, a confrontation with MacKenzie Gore in the dugout and questions about his health, Victor Robles was placed back on the 10-day injured list today with back spasms in the lumbar spine, with the Nationals selecting the contract of Derek Hill from Triple-A Rochester to take his spot on the active roster

It was a rough couple of days in the field since Robles was reinstated from the IL on Friday after he seemingly recovered the same back spasms that had him inactive since May 8. On Monday, he got a late break on a ball over his head that turned into an RBI triple after he crashed into the wall trying to get back to make the catch. Then last night, he let a ball land in front of him while slowly moving to his left, leading to the animated discussion with Gore. Later in the game, he only made it to first base on a line drive off the left field wall and then struggled to go first-to-third on CJ Abrams’ double to right-center.

Davey Martinez mentioned after the game that he was going to have a discussion with Robles to see how he felt.

“We made a move today. We put Victor on the IL,” Martinez said before this afternoon’s finale against the Cardinals. “As I said last night, I was gonna have a conversation with him. I talked to him last night. I had to really stress that he needed to be honest with me. And he said he was a bit sore and that it bothered him running. It doesn't bother him hitting, it bothers him running.

It doesn’t get any easier to say, but it remains true: The Nationals need a win. Ideally, they would win their next two games to end this homestand on a somewhat positive note. They’re 0-5 since returning to D.C. last week and have only won two of their last 15 games.

Trevor Williams gets the start this afternoon in the finale against the Cardinals. The right-hander is 3-4 with a 4.50 ERA and 1.414 WHIP in his first 14 starts. He was roughed up for five runs over 4 ⅓ innings Friday against the Marlins.

Miles Mikolas gets the ball for St. Louis. The 34-year-old right-hander is 4-4 with a 4.36 ERA and 1.362 WHIP over his first 14 starts this season. He too has been beat up by opposing lineups recently, giving up 11 runs over 12 innings for an 8.25 ERA over his last two starts against the Reds and Mets.

The Nationals made a roster move this afternoon, placing Victor Robles back on the 10-day with back spasms in the lumbar spine and selected the contract of Derek Hill from Triple-A Rochester. Hill is immediately in the lineup, batting eighth and playing center field.

Unfortunately, there is rain in the forecast all day in the District. The Cardinals depart D.C. tonight for their two-game series against the Cubs in London this weekend, while the Nats have to bounce back for a makeup game against the Diamondbacks here tomorrow afternoon (which also has rain in the forecast) before they head to the West Coast for the fourth time.

MacKenzie Gore and Victor Robles drew most of the attention Tuesday night, but there were plenty of other factors that contributed to the Nationals’ 9-3 loss to the Cardinals, their fifth straight in this homestand and 13th in their last 15 games overall. …

* Another weak offensive performance was mitigated only somewhat by two late runs scored to put a small dent into an already lopsided margin.

The Nats managed all of one run on four hits against Jordan Montgomery, who had won only one of his previous 12 starts but managed to dominate for seven innings this time. The other two runs came late against Drew VerHagen and Jake Woodford with the game already out of reach.

The Nationals’ average exit velocity off Montgomery was only 80.7 mph. They didn’t have one batted ball hit over 100 mph against the St. Louis left-hander. (For comparison’s sake, the average exit velocity off Gore was 95.4 mph, with eight balls hit at 100 mph or harder against him.)

Equally troubling was the continued lack of patience from the Nats. They drew only one walk in the game (by Stone Garrett). That’s the seventh straight game they’ve drawn two or fewer walks. They’ve drawn a grand total of 20 free passes over their last 15 games (13 of which they’ve lost).

The frustration of a team-wide slump that is now approaching three weeks reached what was perhaps an inevitable low point tonight, when MacKenzie Gore confronted Victor Robles in the Nationals dugout after the latter didn’t make a play on what looked like a routine fly ball to center.

The brief confrontation, which lasted only a few seconds and was relatively tame compared to more dramatic incidents widely remembered from that same dugout over the last decade and a half, was not the reason the Nationals lost the fifth straight game of this homestand, this one by the lopsided count of 9-3 to the Cardinals.

A lack of any sustained offense by the power-starved Nats lineup certainly played a key role. As did Gore’s struggles on the mound on a night the young left-hander gave up a pair of homers and five total runs across six innings. A blowup ninth inning that saw Hunter Harvey serve up a two-run homer and CJ Abrams airmail a throw to first only made things worse.

Suffice it to say, Davey Martinez would seem to have plenty on his plate right now, a number of issues that need to be fixed lest things spiral out of control for a rebuilding Nationals club that legitimately looked like it had turned a corner only 2 1/2 weeks ago but is now reeling from 13 losses in its last 15 games.

The manager's message after this loss, though, wasn't all that different from previous ones. He may have been frustrated by the loss and the factors that contributed to it, but he didn't see reason to publicly scold his team at the end of the night.

Carter Kieboom’s path back to the major leagues has taken another step backward.

The oft-injured former first-round pick is back on the injured list at Triple-A Rochester, this time with a left oblique issue. He’s scheduled to undergo an MRI to determine the extent of the injury, Nationals manager Davey Martinez said.

This latest injury comes barely one month after Kieboom finally started playing every day at Rochester after a long recovery from Tommy John surgery. The 25-year-old third baseman missed all of the 2022 season, then remained at extended spring training throughout April while dealing with a shoulder problem.

After a four-game rehab stint at Double-A Harrisburg, Kieboom was activated off the IL and debuted for Rochester on May 9. In 26 games since, he hit .264 with six doubles, one triple, three homers, 18 RBIs, a .366 on-base percentage and .790 OPS.

“He’s worked really hard to get back to where he’s at,” Martinez said. “He’s had all these little nagging injuries. And then again, people don’t realize how tough it is to play every day (in) this game. It’s tough. When he’s not used to doing it for over a year and he’s playing every day, your body sometimes reacts to it. Hopefully this is just a minor setback and we can get him back on the field, because he’s been hitting the ball really well.”

The Nationals need a win. It doesn’t matter how they get it. It doesn’t matter who makes it happen. They just need to win a game for the first time since Thursday in Houston and for only the third time in their last 15 games.

There are multiple paths toward that outcome, but the best of them would be a top-notch start from MacKenzie Gore. The left-hander shut out the Astros over 5 2/3 innings in that aforementioned game Thursday evening. He faded a bit in the sixth, and with his pitch count rising, Davey Martinez decided not to push him any farther. But the performance was a good one, and the Nats would love to get something like that (or even better) tonight.

Jordan Montgomery is the Cardinals’ starter, and the lefty has been good this month with a 2.00 ERA and 18 strikeouts in 18 innings. The Nationals have been better against left-handers than right-handers this season, but that wasn’t true over the weekend against the Marlins. Martinez has his usual lineup for these matchups, with Stone Garrett in left field and batting fifth. Riley Adams gets the start behind the plate, with Keibert Ruiz sitting.

Not so long ago – 2 1/2 weeks, to be precise – the Nationals appeared to be making real progress.

With an 8-7 win over the Phillies on June 2, the Nats improved to 25-32 overall. They even owned a winning record over nearly one-quarter of a full season, going 20-19 after opening the year a dismal 5-13. They were on pace for a 71-win season, which would be a dramatic improvement from a 55-107 fiasco in 2022.

Josiah Gray and MacKenzie Gore were leading the pitching staff, each making a case for All-Star consideration. The lineup, while still lacking in the power department, was managing to string together rallies with some regularity, scoring six or more runs five times in a span of 11 games. Young potential cornerstones Keibert Ruiz, CJ Abrams and Luis Garcia were making positive contributions.

In that moment, it was fair for anyone who has watched this franchise’s decline from World Series champs to full-scale rebuild to wonder if the worst days of this painful process were now in the past.

Then the Nationals started losing. And losing more. And losing even more.

As he impressed throughout April and May with the best sustained stretch of his young career, one question loomed over Josiah Gray: Could he continue to keep the ball in the yard all summer, avoiding the back-breaking home runs that spoiled his 2022 season?

Four starts into June, the initial answer to that question is not an encouraging one. Gray is serving up homers again, and this afternoon it cost him more than in any previous outing this year.

Despite early support from his teammates to the tune of a five-run lead, Gray gave it all back and more in an 8-6 loss to the Cardinals, the critical sequence coming in the top of the fifth when he surrendered back-to-back homers to turn a game the Nationals once controlled into yet another demoralizing loss.

"The offense has been phenomenal for me out there pitching. I can't applaud those guys enough," Gray said. "I've just got to be better and not squander a five-run lead."

The Nats’ 12th loss in 14 games differed from most that preceded it, because they actually hit well in this one. They jumped all over St. Louis starter Jack Flaherty, jumping out to a 5-0 lead after two innings and putting Gray in prime position to take care of the rest.

Jeimer Candelario is back in the Nationals lineup this afternoon, and while that wouldn’t seem to be a dramatic change, for this particular lineup at this particular time, it is quite significant.

Candelario was scratched from the lineup Sunday about an hour prior to first pitch with a sore right thumb after getting jammed the previous evening. Michael Chavis, who was supposed to be filling in at first base for the day, shifted to third base, with Dominic Smith, who was supposed to have the day off, starting at first base after all.

The end result: The Nats managed only two runs on eight hits in a 4-2 loss to the Marlins, with Chavis going 0-for-4 with three strikeouts and Smith going 0-for-4 with three groundouts to first.

Candelario may not be thought of elsewhere as a premier, middle-of-the-order bat, but he has become critical to the Nationals’ chances of scoring runs as this season has played out. His .788 OPS ranks second among all regulars on the club, behind Lane Thomas’ .822 mark. His 21 doubles rank third in the National League. And he has three Defensive Runs Saved at third base, providing steady play in the field since Opening Day.

His absence Sunday was noticeable.

The season is nearly halfway complete. The All-Star break is three weeks away. And today, two of the worst teams in the National League open a three-game series, one of them expected, one of them definitely not expected.

The Nationals, as much as everyone would’ve liked to believe, remain at the bottom of the NL East, a position they have taken firm control over while dropping 14 of their last 18 games. But the Cardinals were not supposed to be at the bottom of the NL Central, owners of a 29-43 record this deep into the season.

Suffice it to say, both teams will enter this series feeling like they need to win two of three to right their respective ships. Only one can prevail. For the Nats to do it, they’re simply going to have to start scoring more runs. They’re averaging only 3.2 runs over their last 13 games, with a .275 on-base percentage and .367 slugging percentage. It’s tough to win games like that. Perhaps they can generate some offense (and especially be patient) against St. Louis’ Jack Flaherty, who has issued a league-high 43 walks in 73 2/3 innings.

Josiah Gray led the league in walks last season, and though it has remained an issue this year, he stepped up big-time with zero free passes in a seven-inning start last week in Houston. Gray did give up four runs, but he was pleased with his process throughout that game (if not the results themselves).

It was something of a throwaway line from Davey Martinez during a postgame press conference that didn’t include many bright spots.

Minutes after his Nationals lost for the 14th time in 18 games overall, the sixth straight time against the Marlins, Martinez was mentioning Lane Thomas’ third-inning homer (which ultimately accounted for all of the team’s runs during the 4-2 loss) and how it was just the latest in an ongoing string of big hits by the starting right fielder.

“We talk about all these guys for the All-Star Game, right now Lane Thomas is possibly a guy that could make the All-Star team for us,” Martinez said. “He’s played that well.”

Lane Thomas, All-Star? It’s not a crazy thought.

Sunday’s performance left Thomas sporting a .287 batting average, 11 homers, 35 RBIs and an .822 OPS. That final number ranks 14th among all National League outfielders, so it’s not exactly elite. But it is solid, it’s far and away the best mark among all Nats regulars and it continues to rise.

The ball made a loud sound off Stone Garrett’s bat, a 105-mph bullet, and headed in the air toward deep left-center. A Father’s Day crowd of 25,339 at Nationals Park that had little reason to get excited most of the afternoon briefly rose with the kind of anticipation you’d expect from such loud contact at a big moment in a ballgame.

And then everyone slinked back into their seats as Jonathan Davis hauled in the ball at the warning track to end the bottom of the sixth, the Nationals still trailing the Marlins by two runs. Garrett, who came about 20 feet shy of giving his team the lead, slammed his helmet in frustration as he arrived at first base.

"I thought it was gone off the bat," teammate Lane Thomas said. "I think he did, too."

"We thought once he hit it," manager Davey Martinez said, "it was going to be a different ballgame."

The feeling of frustration was mutual throughout the ballpark as the Nats slogged their way through yet another loss to the division foe that somehow has become their white whale.

When the Nationals embarked on a 16-games-in-16-days stretch earlier this week, Davey Martinez began to map out scheduled days off for various members of his everyday lineup. The idea: Make sure everyone gets a break at some point, hopefully on a day when the pitching matchup is conducive to it.

So, Luis García sat Wednesday against Astros left-hander Framber Valdez. Joey Meneses sat Thursday against Houston right-hander Christian Javier. Keibert Ruiz sat Saturday against Marlins lefty Braxton Garrett. And today, Martinez planned to sit both Dominic Smith and CJ Abrams against Miami lefty Jesús Luzardo … until circumstances forced a late change.

“I planned these probably a week ago,” Martinez said. “We’ve had a tough go, all the day games, traveling. I wanted to try to give these guys some days off.”

Smith was due to sit for only the second time in 46 games, but the second time in eight days. In both cases, Michael Chavis was set to make the start at first base in his place, with Meneses remaining as designated hitter.

That plan, however, changed about an hour before first pitch when Jeimer Candelario was scratched from the lineup with a sore right thumb. The veteran third baseman is still available to pinch-hit, according to the Nationals.

The Nationals keep finding themselves in this position, needing a win to avoid a series sweep. This is actually the fifth time in their last six series they’ve lost the opening two games to an opponent. In three of the previous cases (Dodgers, Braves, Astros) they found a way to salvage a win in the finale. They never had a chance to do it in the fourth series, because the finale against the Diamondbacks was postponed due to hazardous air quality. (We’ll see how Thursday’s makeup game shakes out.)

So if the pattern holds true, the Nats will actually beat the Marlins this afternoon and avoid the sweep. Then again, they still haven’t beaten the Marlins this season in five tries, having been swept in Miami last month and now finding themselves in danger of it happening again today.

We’ve talked a lot about pitching throughout this rough stretch, but let’s not give the lineup a free pass. The Nationals have averaged only 3.3 runs, 8.2 hits and a paltry 1.4 walks over their last 12 games (of which they’ve won only two). So they’ve got to do a better job making Jesús Luzardo work today. The long-ago Nats prospect continues to be an enigma: Over his last six starts, he’s alternated between allowing five or more runs or only one run (including once against the Nats).

Patrick Corbin gets the start on the other side. He was solid against the Astros, allowing only two runs over five innings, though he did issue a whopping five walks. If he can hold Miami in check, Davey Martinez should be able to turn to his top relievers today.

Update: Jeimer Candelario was a late scratch from the lineup for undisclosed reasons. Michael Chavis will slide over to third base, and Dominic Smith (who was supposed to sit today) will start at first base.

It takes a lot for the Nationals to beat the Marlins these days. Actually, no one can say for sure what it takes to beat the Marlins this season, because they’ve now had five opportunities to do it and have yet to emerge victorious.

You would think, though, most paths to success would include clutch hitting and quality relief pitching. The Nats got neither of those during today’s frustrating 5-2 loss to Miami.

A lineup that gave itself only a few chances to drive in runs did so only twice, stranding a runner in scoring position in three different innings. And Davey Martinez, whose bullpen was without the services of several arms typically used in high-leverage spots, watched as failed starter-turned-reliever Chad Kuhl made a mess of the decisive seventh inning and Rule 5 pick Thaddeus Ward surrendered two big insurance runs in the top of the ninth to put the game out of reach.

So it was the Nationals lost yet again to their plucky division rivals from South Beach. They are now 0-5 against them this season despite being outscored by only eight runs in total. And they’re an unfathomable 4-20 dating back to the start of the 2022 season.

"The thing is, it's almost like we've got to play perfectly," Martinez said. "And that's tough to do every night. If we don't chase, do some other things, the outcome might be a little better. We've got to keep playing hard. Get on base for the next guy. When we do that, we actually score a few runs."

When looking for reasons to explain the Nationals’ more competitive play early this season, it was easy to point to the club’s improved defense as a significant factor.

After rating as the majors’ worst defensive team in 2022, the Nats ended April ranked 22nd with minus-4 Defensive Runs Saved. That’s far from excellent play in the field, but it did represent real improvement from the previous year.

When they take the field this afternoon, though, the Nationals find themselves back at the bottom of the list. They entered the day with minus-29 DRS, tied with the Athletics for worst in the sport.

Defensive metrics, of course, remain far from a perfect measurement of actual defensive play. But the eye test also seems to suggest the team’s performance has regressed in this area over the last month or so.

“I still feel like we’re playing pretty good defense,” manager Davey Martinez insisted today. “Look, you’ve got to remember we’ve got two guys that are really young in the middle of the field, and it’s going to be part of the process. But I think overall they’re doing well.”

The Nationals, as you may have heard by now, just can’t beat the Marlins. Friday night’s 6-5 loss left them 0-4 this season against Miami and a staggering 4-19 over the last two seasons. How is that possible? Credit to the Marlins, who to be sure are an improved team with a good pitching staff. But that’s an absurd winning percentage against any opponent, no matter how good.

The Nats will try to reverse that trend this afternoon in the second game of the weekend series. They’ll have Jake Irvin back on the mound after a 10-day layoff. Thanks to an off-day at the beginning of the week, the team decided to skip over Irvin’s turn in the rotation and give the rookie a chance to rest and work on some things in the bullpen. He was quite excited about the way his last throwing session went. We’ll see if that actually translates into positive results in today’s game.

The Marlins send left-hander Braxton Garrett to the mound, so Davey Martinez has his right-handed-heavy lineup in there. That includes Stone Garrett, now officially part of a left field platoon with Corey Dickerson. And it includes Riley Adams, who gets the start behind the plate while Keibert Ruiz gets the day off.

After missing 33 games, Victor Robles finally returned to the Nationals lineup last night.

Before the series opener against the Marlins, a 6-5 loss, the Nationals returned Robles from his rehab assignment and reinstated him from the 10-day injured list while optioning Alex Call down to Triple-A Rochester. Robles had been on the IL since May 8 with what the team originally called back spasms.

But it turned out to be a slightly more serious back injury that kept him sidelined for over a month.

“When I first hit the injured list, the biggest thing I was very frustrated,” Robles said via interpreter Octavio Martinez. “Frustrated with the fact that I wasn't able to swing. I felt like my back was real tight and it made me immobile a little bit. But with the hard work of our trainers here, they've done a great job of trying to get me back on the field. And I still feel it a little bit running, but overall I feel good swinging the bat.”

He had no problem swinging the bat before the injury, hitting .292 with four doubles, a triple, eight RBIs, 10 walks, 13 runs and eight stolen bases in 31 games to start the season. And he picked up right where he left off when he was finally able to start a rehab assignment with Rochester, reaching base in all four games and going 4-for-7 (.571) with a double, two home runs, five RBIs, a walk and five runs scored in his final two outings with the Red Wings.

The Nationals came into this weekend’s three-game series against the Marlins needing to find some way to beat their divisional foes.

Entering tonight, the Nats were 4-18 with a -41 run differential against the Fish since the start of last season. They played tight but were ultimately swept out of Miami last month, losing all three games by a total of four runs.

The Marlins aren’t world-beaters. Although they began the night in second place in the National League East, they had a -30 run differential on the year.

That ever so slightly improved tonight as did their record against the Nats. Despite another hard-fought game, the Nationals dropped the series opener 6-5 in front of an announced crowd of 22,379 at Nats Park, with the Marlins improving to 18-5 in one-run games already this season.

“We were down. We got a good pitcher in there. We come back," manager Davey Martinez said after the loss. "Score some runs early and then the bats, we had a couple of opportunities to score again. We just couldn't capitalize. And then big moment, ball up the middle. I think that inning really started with the walk. We always talk about not walking guys because, especially early in innings, it's gonna bite you. But overall, I thought you know we did well, we played well, we came back, we kept coming back. We just couldn't score any runs at the end.”

Victor Robles walked into the Nationals clubhouse with a little more hop in his step than he had over the past month-plus. He wasn’t very mobile or flexible while dealing with a back injury that had him on the 10-day injured list since May 8.

Robles was back to his energetic self today because he was returned from his rehab assignment and reinstated to the active roster this afternoon, while Alex Call was optioned to Triple-A Rochester in a corresponding move.

“We made a move today before the game,” manager Davey Martinez said to open his pregame media session ahead of tonight’s opener against the Marlins. “Victor is back with us. He checked all the boxes down there. He feels really good. So we optioned Call down. Look, I can't say enough about Alex. He played unbelievable defense for us. He was out there every day. He's an unbelievable competitor, a good teammate. We want to send him down and kind of get his swing straightened out a little bit. I don't think it'll be the last you've seen of Alex. But he was struggling a little bit with the bat. So we get Victor back. He was swinging the bat really well before he got hurt. So hopefully he'll jump-start us again.”

Robles was off to a good start to the season, hitting .292 with four doubles, a triple, eight RBIs, 10 walks, 13 runs and eight stolen bases in 31 games before he was placed on the IL. And he continued that success in his rehab in Rochester, reaching base in all four games and going 4-for-7 (.571) with a double, two home runs, five RBIs, a walk and five runs scored in his final two outings with the Red Wings.

The 26-year-old is back in center field and batting eighth tonight as the Nats face reigning National League Cy Young Award winner Sandy Alcantara. But even as he’s thrust back into the starting lineup, the Nats will continue to monitor how his back is feeling.
