ST. PETERSBURG, Fla. - Cole Irvin is starting for the Orioles tonight on normal rest, the only certainty in the rotation for the four-game series against the Rays at Tropicana Field.

Irvin has allowed two runs in 11 1/3 innings since returning to the rotation, and he’s carrying a 2.61 ERA and 1.142 WHIP in nine starts. He faced the Rays on Sunday at Camden Yards and allowed two runs in 6 1/3 innings. José Caballero led off the seventh with a homer.

Irvin has a 3.86 ERA and 1.169 WHIP in five career games (four starts) against the Rays. He’s surrendered six runs and 14 hits in 13 1/3 innings at Tropicana Field.

The starters for the next three games remain TBA.

Jordan Westburg is starting at second base and Ramón Urías is at third. Connor Norby goes to the bench.

It's been a weird stretch for the Nationals. One week ago, they were feeling really good about themselves, having just won series over both the Mariners and Braves. Since then, they've lost a series to the Guardians, been swept by the Mets and lost Thursday night's series opener to the Braves despite the fact Mitchell Parker carried a no-hitter into the sixth inning.

The Nats also lost Trevor Williams to an injury that's going to sideline him for a while, called up DJ Herz to make his major league debut and are counting down the days until Josiah Gray and Cade Cavalli are ready to come off the injured list. But about that lineup that has now been held to two or fewer runs in 25 of 62 games played this season ...

Let's take some time this morning to answer your questions about the team. Please submit your inquiries in the comments section below, then check back later for my replies.

Having already passed just about every test thrown his way in his first two months in the majors, Mitchell Parker stared down a new challenge tonight: Face an opponent for the second time, and ideally try to beat that club again.

Parker did everything he could to pass the test, carrying a no-hitter into the sixth inning against the Braves and a shutout into the seventh. But he ultimately departed with no-decision after surrendering a game-tying homer in the seventh, and was forced to watch and see if his teammates could pull off the win late.

They could not. Hunter Harvey, one of the most reliable late-inning relievers in the sport, gave up three runs in the top of the eighth, and the Nationals lineup did nothing against the Atlanta bullpen en route to a disheartening 5-2 loss.

The Nats’ fourth straight loss bore some resemblance to the previous ones in their inability to produce at the plate early on. This one differed from the others, though, in the manner the back end of their bullpen gave up the decisive runs late.

"We've played some good teams lately, and it just seems like on nights we hit and pitch, they're just not on the same night," right-fielder Lane Thomas said. "We took some good swings tonight. You've just got to take more than two off a team like that."

The Nationals’ offensive identity this season was established early in April. Knowing they weren’t likely to hit for much power, they decided their best chance at scoring runs was to get on base and then use their speed abilities to get around the bases as quickly as possible.

Two months later, the Nats lead the majors with 95 stolen bases, with four individuals already in double digits and three others with eight steals.

But they’re also getting thrown out a decent amount, especially in recent games. The Nationals have been caught stealing 24 times in total, third-most in the majors. And they’ve been caught 10 times in their last 14 games, a particularly rough stretch that has at times cost them.

That drop in success rate, from 85 percent through their first 47 games to 64 percent during these last 14 games, coincides with the team’s scoring output dropping from 4.1 runs to 3.8 runs per game. Manager Davey Martinez sees a correlation.

“I think we’re trying to push the envelope a little too much because we’re not scoring any runs, and that happens because as a team we start pressing and trying to make things happen,” he said. “I think we’ll get back to (stealing successfully) as soon as our guys start swinging the bats better. The success rate will definitely go up.”

This homestand started off in miserable fashion for the Nationals, who were swept by the Mets and didn’t look particularly good in the process. They now have to try to salvage things with a four-game series against a team that on paper is far more intimidating in the Braves.

The good news: The Nats just took three of four in Atlanta last week, so they should feel confident about themselves entering this matchup. They won those three games thanks to some stellar pitching, including another quality start from the guy who takes the mound tonight: Mitchell Parker.

Parker allowed three runs while reaching the seventh inning in that game at Truist Park. The rookie left-hander tonight makes his 10th career start, and he has yet to surrender more than three runs in any of them. This will, however, be the first time he faces an opponent a second time, so it will be very interesting to see if he or the Braves make any adjustments.

On the mound for Atlanta is old friend Reynaldo López. The 30-year-old right-hander made his major league debut for the Nationals way back in 2016, then was part of the blockbuster trade with the White Sox for Adam Eaton. He’s had an up-and-down, nomadic career since and is now pitching for his fourth organization in the last two years, but he’s been outstanding so far since joining the Braves: a 1.73 ERA and 1.081 WHIP in 10 starts.

April was an especially encouraging month for the Nationals, who played .500 ball for the entire month and saw one of their most important young players take his game to another level.

In that opening month to the season, CJ Abrams put forth a titanic offensive slash line: .295/.373/.619. He got on base. He stole bases when presented with the opportunity. He scored runs. He drove in runs. He drove in himself. It was to be just the beginning of a breakthrough season for the 23-year-old shortstop.

Then came May, and with it a precipitous drop in production. Abrams slashed a far less impressive .205/.216/.304 in the season’s second month. He didn’t get on base. He didn’t steal bases. He didn’t score as many runs. He didn’t drive in as many runs.

And with an 0-for-3 showing Wednesday in the Nationals’ 9-1 loss to the Mets, Abrams’ prolonged slump continued. He’s now batting a mediocre .246 with a .293 on-base percentage and .446 slugging percentage.

Is it any wonder the Nats are 13-19 since May 1, making that April of success feel like a distant memory?

TORONTO – The O's came into Wednesday night looking for their third straight win in Toronto, and a series-clinching win. The script was set just for that, as they took an early 2-0 lead, but the offense fell flat after the second inning and the Blue Jays walked off the O's to win 3-2 in front of 27,929 at Rogers Centre.

The Orioles fall to 39-21 with their third walkoff defeat of the year after two very early on April 6 and 7 to the Pittsburgh Pirates. Tonight's walk-off was aided by a miscue in the field.

Justin Turner led off the ninth against O's closer Craig Kimbrel with his third hit of the night, a single on an 0-2 pitch and was replaced by pinch-runner Cavan Biggio.  

The miscue followed shortly after. Kimbrel tried to pick off Biggio, but his throw went off his body and into right field, allowing Biggio to get into scoring position. Then he moved to third, advancing on an Alejandro Kirk fly-out. 

Runner on third, one out, and now the winning run was 90 feet away as the infield came in. Kimbrel then faced the contact-oriented Isiah Kiner-Falefa. 

The Nationals came home Sunday evening rightfully feeling good about themselves after a winning road trip against a pair of contenders. Next up: a three-game series against a Mets team in disarray in advance of its weekend trip to London to face the Phillies.

What ensued: A three-game sweep at the hands of that supposedly unraveling Mets club that featured two ugly pitching performances, an injury to one of the team’s best starters to date and precious little production from a lineup that has been the roster’s weak link for two months now.

Consider today’s 9-1 shellacking before the fans who waited out a rain delay a new low point to the season. Patrick Corbin was rocked once again. The Nationals lineup looked helpless against Luis Severino. And by day’s end, it was Davey Martinez’s bunch that looked ready to leave town, not the guys heading to England.

"Rough series," Martinez said. "But we can't feel sorry for ourselves. We've got another tough team coming in (the Braves this weekend). We've got to be ready to play tomorrow."

Outscored 23-11 during the sweep, the Nats held a lead after only one of the 27 innings they played. They saw MacKenzie Gore get roughed up for six runs in 4 1/3 innings Monday. They made David Peterson throw only 81 pitches in 6 2/3 innings Tuesday. And today they suffered the worst of both worlds, with Corbin shelled for six runs in 5 1/3 innings while the lineup made Severino throw only 72 pitches through seven scoreless innings before finally plating a run in the eighth.

TORONTO – After two good nights for Orioles’ bats at Rogers Centre, producing 7-2 and 10-1 wins, the Birds look for three in a row against the Blue Jays tonight as this series continues.

Last night’s win improved the Orioles to 13-4 (.765) in American League East games and they are 3-1 versus the Blue Jays. The O’s also hold a 13-4 mark against the Blue Jays since the start of last season. And the Orioles are 9-1 in their past 10 games at Rogers Centre with a plus-39 run differential, outscoring the Blue Jays 66-27 in those games.

The Orioles are 6-2 in the first eight of 14 straight games within the division, playing in order, the Red Sox, Rays, Jays and Rays again.

The Orioles' plus-88 run differential for the year ranks third-best in the majors and second in the AL. The New York Yankees are first at plus-111. And New York (43-19) continues to lead the division by 2.5 games over the Orioles. The red-hot Yankees have won six in a row, 10 of 12 and 17 of their past 21 games.

Toronto had won five of its last six and nine of the past 14 heading into this series. But with Tuesday’s loss the Blue Jays are 28-32 and fall to 7-10 in division games. They have scored two runs or less 23 times this season including twice in this series.

TORONTO – Moments after confirming that O’s pitching prospect Cade Povich is in fact in Toronto and on the taxi squad for the Orioles, manager Brandon Hyde was unable (or perhaps unwilling) to provide the next date for a Kyle Bradish (1-0, 3.18 ERA) start.

“I don’t know yet, no,” Hyde said when asked if he has a day for Bradish’s next outing.

Bradish last pitched on Saturday at home versus the Rays. He presumably will not be on the mound tomorrow, which would have marked his spot in the rotation.

On May 26 versus the White Sox in Chicago, Bradish pitched seven no-hit innings on 103 pitches and lowered his ERA to 1.75. But pitching with an extra day of rest in that game with Tampa Bay he allowed five runs over 2 2/3 on 76 pitches.

Bradish’s season got a late start after he had a platelet-rich plasma injection in January to promote the healing of a right elbow UCL sprain.

Josiah Gray is ready to pitch in a competitive game again.

Gray, who has spent nearly two months on the 15-day injured list with a flexor strain in his forearm, has been cleared to begin a minor league rehab assignment. The exact date and location hasn’t been finalized yet, but manager Davey Martinez suggested it’s most likely to come Sunday at Single-A Fredericksburg.

“I would like to send him to the closest affiliate for now, because I want him to come back here after he pitches,” Martinez said. “So if Fredericksburg is home, that’s probably where he’ll go.”

The Fred Nats indeed are home Sunday afternoon against Kannapolis, so that appears to be the answer.

Gray landed on the IL on April 9 after two rough starts to his season. He slowly built his arm back up and in recent weeks pitched in three simulated games against teammates. The last of those came Tuesday when the right-hander threw 65 pitches over three innings.

Jordan Westburg is starting at second base tonight and Connor Norby is out of the lineup after homering last night for his first major league hit.

Norby is the 12^th player in club history whose first hit is a home run.

Ramón Urías is playing third base. Kyle Stowers is in left field, Cedric Mullins is in center and Ryan O’Hearn is in right.

Anthony Santander is the designated hitter.

Ryan Mountcastle homered twice last night and is 29-for-91 (.319) with seven doubles, eight home runs, 26 RBIs and a 1.044 OPS in 24 career games at Rogers Centre.

The Nationals are scheduled to play the Mets at 4:05 p.m. today. The Mets are scheduled to fly to London after the game in advance of their weekend series against the Phillies. And it’s scheduled to begin raining here later this afternoon. So this creates a bit of a predicament.

The good news: The Mets are back here the first week of July. So there’s really little reason for the Nats and Major League Baseball to wait around for a long time in hopes of playing today. A postponement would not be surprising.

But until we hear otherwise, we’ll assume they’re going to play. And if they do, the Nationals will need a win to avoid what would be an awfully disappointing sweep at the hands of the team that trails them in the standings and was kind of in disarray when it arrived in town at the start of the week.

The Nats need to hit, and they need to hit early and not wait until the New York bullpen takes over. They face Luis Severino this afternoon, and the veteran right-hander has been solid overall (3.52 ERA, 1.172 WHIP) but has allowed five runs in two of his last three starts (against the Marlins and Diamondbacks). In between, he dominated the Giants. So who knows what you’re going to get.

Patrick Corbin has this start for the Nationals, coming off back-to-back quality starts against the Mariners and Guardians. The lefty was quite bad last season in three starts against the Mets, allowing 14 runs and 21 hits in only 15 2/3 innings.

The Orioles haven’t confirmed their starter for Thursday afternoon’s series finale against the Blue Jays. However, one of their top prospects is in the running.

He won’t be far from them.

Left-hander Cade Povich is headed to Toronto and will be placed on the taxi squad later today, according to a source, perhaps setting up his major league debut.

Povich was scheduled to start for Triple-A Norfolk on Thursday at Scranton/Wilkes-Barre. Now he’s an option for the Orioles, who are undecided about Kyle Bradish’s status.

Bradish would be working on his normal turn Thursday, but manager Brandon Hyde told the assembled media yesterday that the club might push him back. If so, Bradish would open the four-game series against the Rays on Friday night in St. Petersburg, Fla. or pitch the following day.

There’s nothing more tempting in baseball than to try to predict a team’s pitching plan for both the short-term and long-term. And there are few exercises that almost always turn up results that don’t come to fruition.

Way back in March, as the Nationals prepped for the season in West Palm Beach, it seemed a given that Trevor Williams’ hold on the fifth spot in the Opening Day rotation was tenuous at best. Shoot, there even seemed to be a reasonable chance he would lose the job to spring training invitee Zach Davies. Then Davies had a blowup start that led to his release and Williams retained his starting job entering the season.

Even so, the leash on Williams figured to be short, especially on the heels of a miserable 2023 season. A couple of bad weeks to begin April and he might be bumped to the bullpen, opening the door for Jackson Rutledge (presumably the first-man up at Triple-A) to get his shot.

Then Williams got off to a great start to the season, and instead the opening in the Nats rotation came via injury to Josiah Gray. The choice to replace Gray wasn’t Rutledge (who was off-schedule at the time) but Mitchell Parker, who was thrown to the wolves at Dodger Stadium and conceivably could be sent back to Rochester one or two rough starts into his career.

Then Parker exceeded everyone’s expectations and now has solidified his place in the big league rotation for the foreseeable future. And alongside the improving MacKenzie Gore and Jake Irvin, plus the still-effective Williams, the Nationals had four quality starters giving their team a chance to win every time they took the mound.

DJ Herz’s major league debut wasn’t the fairytale Mitchell Parker experienced two months ago at Dodger Stadium. Neither was it the nightmare suffered by countless other Nationals rookies over the last decade.

Herz wasn’t great in his first career start. Neither was he bad. The rookie left-hander pitched with some confidence, escaped a couple of early jams, then began to succumb as his evening progressed.

In the end, Herz allowed two runs while he was in the game, plus another two that were charged to him after he departed in the top of the fifth. And because his teammates did very little at the plate themselves, he wound up charged with the loss as the Nationals fell 6-3 to the Mets.

"He was a little nervous," manager Davey Martinez said. "He was sweating like crazy out there. But you know what, in big moments he kind of settled down and threw strikes and looked really good."

The Nats hoped for something more akin to Parker’s sparkling April debut in Los Angeles, when the unheralded rookie left-hander struck out Mookie Betts and Shohei Ohtani, went five strong innings and became the franchise’s first starting pitcher to win his major league debut since Stephen Strasburg.

Trevor Williams will be shut down from throwing for two weeks after an MRI revealed a flexor muscle strain in the right-hander’s forearm. How much time the Nationals veteran starter will need to return after that remains an open question.

“There’s positive news from it: Everything structurally looks good. It’s just going to take some time,” Williams said this afternoon. “That’s the positive news. I wish it was just one start that I was skipping to be able to let my body recover. But unfortunately, it’s not that way.”

The Nats placed Williams on the 15-day injured list today, calling up left-hander DJ Herz from Triple-A Rochester to make his major league debut tonight against the Mets. The IL move is backdated to June 1, so Williams technically will be available to return as soon as June 16. But there doesn’t appear to be any reason to believe he’ll actually be ready that soon.

Williams said he felt fine during his last start Thursday in Atlanta, when he held the Braves to one run over 5 2/3 innings, throwing 95 pitches (his second-highest total of the season). But when he went to play catch the next day in Cleveland, he said his arm didn’t respond the way it usually does. And when the discomfort lingered through the weekend, the Nationals had him get an MRI to determine if there was an injury.

That MRI showed no issues with Williams’ elbow ligament or tendons, so the injury is purely muscular. Manager Davey Martinez called that diagnosis “best-case scenario.”

Who’s ready to watch a major league debut tonight? An unexpected one, at that.

Trevor Williams was supposed to start the second game of this series against the Mets, but he was placed on the 15-day injured list with a flexor muscle strain in his right arm, so DJ Herz got the call from Triple-A Rochester and will make his first major league start tonight instead.

Who is DJ Herz? He’s a 23-year-old left-hander, acquired last summer from the Cubs for Jeimer Candelario. He’s had big strikeout numbers in the minors, but he’s also had big walk numbers. He’s been a lot better in recent outings, though, and in his last start Thursday he struck out 10 with only one walk over 5 2/3 innings. Herz is going to be amped up big-time. His ability to control his emotions will go a long way toward determining if he has success or not.

Some run support would also help, of course. The Nationals scored seven runs Monday night, and they’d love to do the same tonight against New York left-hander David Peterson, who makes only his second start of the season after recovering from hip surgery.

The Nationals rotation, a surprising strength for the club so far this season, is getting a surprising shakeup today.

Trevor Williams has been placed on the 15-day injured list with a flexor muscle strain, opening the door for left-hander DJ Herz to make his major league debut tonight.

Williams was scheduled to face the Mets in the second game of a three-game series, hoping to continue his strong run to begin the season. The 32-year-old right-hander is 5-0 with a 2.22 ERA and 1.076 WHIP through 11 starts, having surrendered only two homers one year after he led the league with 34 homers allowed.

Williams last pitched Thursday in Atlanta and showed no outward signs of physical ailment. He held the Braves to one run over 5 2/3 innings, throwing 95 pitches (his second-highest total of the season).

The flexor muscle strain is the same injury suffered by Josiah Gray in April. Gray is scheduled to face live hitters today for the third time since going on the IL, and if all goes well is expected to begin a minor league rehab assignment after that.

The Washington Nationals recalled left-handed pitcher DJ Herz from Triple-A Rochester and placed right-handed pitcher Trevor Williams on the 15-day Injured List (retroactive to June 1) with a right flexor muscle strain on Tuesday. Nationals President of Baseball Operations and General Manager Mike Rizzo made the announcement. Herz will start and make his Major League debut tonight against the New York Mets at Nationals Park.

Herz, 23, is 3-2 with a 3.75 ERA, 42 strikeouts and a .177 opponents’ batting average in nine starts for the Red Wings this season. Over his last four starts, Herz is 3-0 with a 2.50 ERA (5 ER/18.0 IP), 25 strikeouts and a .148 average against. In his last start on May 30 vs. St. Paul (MIN), he struck out 10 and allowed one run on two hits and one walk in 5.1 innings.

Herz leads all of Minor League Baseball with a .176 opponents’ batting average and is third with 13.09 strikeouts per 9.0 innings since the start of the 2021 season (min. 250.0 IP). In parts of five Minor League seasons, Herz is 13-16 with a 3.65 ERA with 455 strikeouts in 317.2 innings and has held opposing hitters to a .178 batting average.

Originally an eighth-round pick by the Chicago Cubs in 2019 from Sanford High School in Fayetteville, N.C., Herz was acquired by the Nationals on July 31, 2023, with Kevin Made in exchange for Jeimer Candelario. He is currently ranked as the Nationals No. 12 prospect according to MLB Pipeline.

Williams, 32, is 5-0 with a 2.22 ERA (14 ER / 56.2 IP), 47 strikeouts and 16 walks in 11 starts this season.
