SAN DIEGO – If there was one thing the Nationals could cling to as evidence of improvement from Patrick Corbin this season, it was the fact he has almost always pitched well enough to give his team a chance.

That’s admittedly a low bar for acceptable pitching performances. But the Nats had no choice but to set the bar low with Corbin, given his immense struggles the last three seasons. If he was at least doing enough to give them a chance to win, that would have to be considered a success, right?

What, then, to make of Corbin’s performance tonight, in which the left-hander most certainly did not give his team a chance during a 13-3 blowout loss to the Padres?

A six-run bottom of the fifth foiled whatever possibility remained for Corbin to leave the mound with the Nationals in a reasonable position. That frame included every manner of calamity, some of them not the left-hander’s fault but plenty of them still falling on his shoulders.

A four-run bottom of the seventh off Chad Kuhl, now the owner of an 8.45 ERA, didn’t help matters. Nor did the two-run homer Thaddeus Ward surrender to Juan Soto (who reached base four times in five plate appearances) in the eighth.

SAN DIEGO – The path that ultimately brought Joe La Sorsa to the visitors’ clubhouse at Petco Park this afternoon was as follows: Montgomery, Ala., to Durham, N.C., to St. Petersburg, Fla., to DFA Purgatory to Rochester, N.Y., to Washington, where the left-hander spent barely more than 24 hours learning his new surroundings before hopping aboard the Nationals’ charter flight for a nine-game road trip that will take the team from San Diego to Seattle to Philadelphia.

“I haven’t really had more than a month any place. That’s pretty much been it,” La Sorsa said with a hint of both exasperation and appreciation. “But I feel very comfortable here. How I’ve been treated here, and everything with the Nationals so far is leaving a very good first impression.”

Plucked off waivers after the Rays designated him for assignment earlier this month, only two games into his big league career, La Sorsa made four relief appearances at Triple-A Rochester before getting the call to come to D.C. and replace the injured Carl Edwards Jr. in the Nats bullpen.

He didn’t appear in either Wednesday or Thursday’s game, but chances are he’ll make his debut sometime this weekend at Petco Park, perhaps thrown into the fire to face Juan Soto in a big spot late in a game.

Davey Martinez has been wanting a left-handed reliever for nearly two months now since the Anthony Banda experiment was aborted. He’s got one now in La Sorsa, an unassuming, mustachioed, 25-year-old rookie from Westchester County, N.Y., and St. John’s University.

SAN DIEGO – A very pleasant evening to you from one of the most pleasant ballparks in America. Maybe the change in locations will be good for the Nationals, who just endured through a dismal, 1-6 homestand and continue to struggle like crazy in D.C, with a 13-27 record. The story has been much better on the road, where they’re actually 15-19. They better hope that trend continues since they now embark on a long, nine-game trip from San Diego to Seattle to Philadelphia.

The Padres were struggling to find their footing when they played at Nationals Park last month, and they’re still kind of stuck in that same spot, entering tonight’s series opener three games under .500, 9 1/2 games back and in fourth place in the National League West. Juan Soto, however, is feeling just fine, thank you very much. Over his last 14 games, the ex-Nat is batting a healthy .353/.453/.588.

It’ll be Patrick Corbin’s job to try to hold Soto and Co. in check tonight. Corbin didn’t face the Padres last month. He’s kind of in a strange place right now where he’s giving up a ton of hits (11 in two of his last three starts) but still keeping the damage to a relative minimum (3-4 runs).

Joe Musgrove gets the start for San Diego. After a brutal start to his season, he’s been much better, going 4-0 with a 2.15 ERA in his last five starts. A Nats lineup that has had all kinds of trouble scoring runs is going to have to figure out the veteran right-hander.

The Nationals made an interesting choice when placing Victor Robles back on the 10-day injured list with back spasms in the lumbar spine.

They could have recalled Alex Call, who was originally optioned down to Triple-A Rochester when Robles was activated Friday, even though it was within 10 days because he would have been replacing an injured player.

But they chose to select the contract of Derek Hill instead.

This is a developmental and evaluation year. The Nats have already seen 64 games of Call, who only hit .209 in the majors. Now it’s time to see what Hill has to offer. Plus, had he not strained his right hamstring in the beginning of March, Hill might have made the Opening Day roster out of spring training instead of Call or Stone Garrett.

“It feels great,” Hill said of being back in a major league clubhouse. “Obviously, this is the dream to play in the big leagues even if you've been here before. I'm just excited to come up here and do whatever I can to help the team.”

Although they lost an off-day, the Nationals were hoping to use this makeup game against the Diamondbacks to create some momentum before heading out on a nine-game road trip.

Yesterday’s win over the Cardinals was only their fourth since the start of June. Putting together back-to-back wins to end this homestand would have made for a happy flight out west.

Davey Martinez applauded his team for playing clean baseball during yesterday’s rainy conditions. But the Nats got sloppy again, committing two errors and allowing four unearned runs in a 5-3 loss to the D-backs in front of 13,251 fans who withstood the misty weather.

"We can't give good teams 28-29 outs. We can't," Martinez said after their 14th loss this month. "I think we had four unearned runs today. Take those away and we're right in the ballgame. So we gotta get better at that, we really do. And if we do that, we're going to be able to compete. So we got to just come back tomorrow and play a good, clean baseball game and see where we're at.”

Weird circumstances surrounded today’s getaway game, which technically was recognized as a one-game series since it was rescheduled from June 8 due to poor air quality in the D.C. area from the Canada wildfires.

Two weeks ago, the Nationals were looking at this date on the calendar and expecting to spend their off-day in sunny San Diego. But because of the postponement of the June 8 finale against the Diamondbacks due to the poor air quality from the Canada wildfires, they’re instead still in cloudy D.C. ready to play an early afternoon makeup game.

That made for an odd schedule this week to end this seven-game homestand before the team embarks on a nine-game road trip, which starts with six consecutive games on the West Coast. They had a late afternoon start on Monday for the Juneteenth federal holiday. They had another 4 p.m. start yesterday as it was still a getaway day for the Cardinals, who had a transatlantic flight to London to play two games against the Cubs. And now they have this early afternoon game against the D-backs, who arrived from Milwaukee last night and will also travel back to the West Coast tonight.

The lost off-day means the Nationals are in the middle of a stretch with games scheduled for 16 straight days. So Davey Martinez has to get creative in finding ways to give guys some rest.

“This would have been a nice day off for us, obviously,” the skipper said during his pregame press conference. “And it would have been in San Diego, which is kind of nice. But you know what, we got to play today. So I know these guys will be ready to play. But finding days off, we played so many days in a row.”

Today’s lineup against the Diamondbacks and left-handed starter Tommy Henry features some regulars getting the day off and some others playing in different positions.

And we’re back. After the Nationals finally got a win here yesterday to end their series against the Cardinals, they’re right back to play today’s makeup game against the Diamondbacks. What should have been the series finale between these two teams two weeks ago was postponed due to the poor air quality from the Canada wildfires to make this now a one-game series before both clubs head to the West Coast tonight.

Jake Irvin will make his ninth major league start this afternoon, seventh here at Nats Park. The rookie bounced back to pitch well on Saturday after having his spot in the rotation skipped the week before, tossing five innings of one-run ball against the Marlins. In his start against the D-backs two weeks ago, he gave up four runs (three earned), five hits and three walks in just four-plus innings.

In a rematch of that June 6 game against Irvin, Tommy Henry will start for the Diamondbacks. The 25-year-old left-hander was tagged for five runs over 4 ⅓ innings, including a grand slam by Stone Garrett in the second inning and a leadoff homer by Lane Thomas in the fifth. In his two starts since against the Phillies and Guardians, Henry gave up seven runs over 10 ⅔ innings for a 5.91 ERA.

While all day yesterday there was rain in the forecast for today, it now seems like we’ll be much drier this afternoon, with the rain supposedly not starting again until this evening.

There have been some very bizarre circumstances and confusing statements surrounding Victor Robles’ back injury.

It all started on May 7 when the 26-year-old first hurt his back while sliding into second base during a game against the Diamondbacks in Arizona. He was placed on the 10-day injured list the following day with what the team then called “back spasms.”

After a while, the injury was suspected to be more serious. It took Robles three weeks to start running and doing agility work. Then a few days later, he started taking full rounds of batting practice.

That was finally a sign he was improving and ready to start working his way back to the team. He started a rehab assignment with Triple-A Rochester on June 9 and reached base in all four games with the Red Wings, going 4-for-7 (.571) with a double, two home runs, five RBIs, a walk and five runs scored in his final two outings.

The time came Friday for Robles to be reinstated from the IL, with Alex Call being optioned down to Rochester. After his first three games back over the weekend, the oddities surrounding Robles were on display Monday and Tuesday.

The situation surrounding this afternoon’s finale between the Nationals and Cardinals was a tricky one.

Rain was in the forecast all day today in the District of Columbia, with only a brief window right around the 4:05 p.m. scheduled start time. The Nationals have a makeup game against the Diamondbacks scheduled for 1 p.m. tomorrow (with more rain in the forecast), with both teams traveling back to the West Coast afterward. And the Cardinals have a transatlantic flight out of D.C. tonight for their two-game weekend series against the Cubs in London.

All of that made for a lot of uncertainty on South Capitol Street.

But as if both teams understood the assignment of playing fast, the Nats and Cards were able to complete this one in a swift 2 hours and 12 minutes, with the home team finally emerging victorious 3-0 in front of a damp 16,191 fans.

This one couldn’t have been scripted better when it came to the weather. A drizzle started in the top of the second inning and had turned into actual rainfall as the game moved into the third.

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.
