Victor Robles is ready to start playing in games again. Another week or so and he should be ready to play for the Nationals again.

Robles will join Triple-A Rochester on a rehab assignment Friday, the final step in the outfielder’s recovery from a back injury that has sidelined him more than a month.

“Hopefully everything goes well and we get him back here soon,” manager Davey Martinez said.

Robles departed Thursday and is expected to play four innings for Rochester, which is on the road at Worcester, on Friday. Given the amount of time he has missed, he will likely build up his workload over several days and could spend a full week on the rehab assignment before the Nats decide to activate him off the 10-day IL.

“He’s got to go out there and play, start getting some at-bats,” Martinez said. “I want to see him do everything that he normally does. If he gets an opportunity to steal some bases, take the extra bases, play good defense, all that stuff.”

With smoke from Canadian wild fires getting worse in the region, Major League Baseball postponed today’s scheduled series finale between the Nationals and Diamondbacks, citing the health risks current conditions pose for players, fans and stadium workers alike.

The teams were able to play Tuesday and Wednesday night as planned under a hazy sky that wasn’t nearly as bad as it was in Philadelphia and New York, where games were postponed Wednesday. They were supposed to finish the three-game series at 1:05 p.m., but the air quality is considerably worse today, with Washington officially categorized as “Code Purple.”

The decision whether to play or not was made by MLB, with consultation with both teams and the MLB Players Association, and was announced about 90 minutes before first pitch.

“This postponement was determined following conversations throughout the day with medical and weather experts and the two impacted clubs regarding clearly hazardous air quality conditions in Washington, D.C.,” the league said in a press release.

This was to be the last time the Nationals and Diamondbacks faced each other this season, but Arizona will now be forced to come back to Washington for a June 22 makeup game at 1:05 p.m., a common off-day for both teams. The Nats begin a West Coast trip to San Diego and Seattle the following day. The D-backs will make a side trip to D.C. in between series at Milwaukee and San Francisco.

Perhaps if other things had progressed in a different manner the rest of the night, Lane Thomas’ throw in the top of the fifth Wednesday would’ve carried more weight. In the end, the play had no bearing on the outcome of the Nationals’ game, a 6-2 loss to the Diamondbacks.

That doesn’t mean it didn’t feel significant in the moment, though. Or that it wasn’t noticed by everyone at Nationals Park.

When Corbin Carroll lined a hit to right to open the top of the fifth, Arizona looked like it was poised to start another rally against Patrick Corbin and perhaps cash in this time after being shut out since taking a quick 3-0 lead in the first. And when Thomas couldn’t cleanly field the ball on a hop, Carroll looked like he was destined for a leadoff double.

Until Thomas retrieved the ball and fired it toward second base, where CJ Abrams made a nice scoop and applied the tag to Carroll in time for the out.

It was a big play in what was a 3-2 game at that moment. And it was only the latest by Thomas, who has really come to his own in right field this season.

They got a quality start out of Patrick Corbin despite another roughshod first inning that set an ominous tone for the evening. They kept it close for most of the proceedings, remaining within one clutch hit of tying the game or taking the lead. Until the bullpen failed to keep it close late in its latest subpar showing.

And so the Nationals found themselves on the wrong end of a 6-2 loss to the Diamondbacks, done in by one of their weaker offensive performances in a while, the three-run hole Corbin dug them into from the outset and the three tack-on runs Carl Edwards Jr. and Jordan Weems surrendered late.

Make it seven losses in nine games for a Nats club that was feeling pretty good about its ability to compete and play .500 ball for more than a month not that long ago but has since regressed while facing stiffer competition.

They aren’t facing the Tigers and Royals anymore. The Nationals have now dropped three straight series to superior opponents, first the Dodgers, then the Phillies and now the Diamondbacks, who will be looking for a three-game sweep Thursday afternoon.

Then comes a road trip to Atlanta and Houston that could threaten to derail much of the forward momentum the Nats had built through most of May. They're a season-worst 11 games under .500, hoping not to keep plummeting. 

The Nationals, for the second straight day, designated a struggling reliever for assignment, with Erasmo Ramírez suffering that fate this afternoon in the wake of a particularly ragged appearance during Tuesday’s loss to the Diamondbacks, and Cory Abbott recalled from Triple-A Rochester to take his spot.

Ramírez joined fellow right-hander Andrés Machado, who was designated for assignment Tuesday, in getting dropped from the active roster. Machado officially cleared waivers and accepted an outright assignment to Rochester today. Because he had already been through that process over the winter, he had the option to declare himself a free agent but instead chose to remain in the organization.

Ramírez will face a similar decision in the next few days. The 33-year-old got the news after retiring only two of the six batters he faced in the top of the sixth Tuesday night, having hit the first batter he faced on the first pitch he threw, nearly hitting the next batter on his next pitch and then committing a balk when he turned to make a pickoff attempt to first base but never threw the ball because nobody was covering.

That outing left Ramírez with an unsightly 6.33 ERA and 1.556 WHIP in 23 games this season, a dramatic drop in effectiveness from the previous year. In 60 games in 2022, Ramírez produced a 2.92 ERA and 1.077 WHIP, earning the team’s Pitcher of the Year Award for his performance.

“It’s tough. Erasmo meant a lot to this team, and to me,” manager Davey Martinez said. “This guy worked really hard to get back to the big leagues and had an unbelievable year last year. This year, he just couldn’t find himself.”

It’s another hazy afternoon in the nation’s capital, with smoke from wildfires in Quebec hovering over the region again. It’s not as bad here as it is in New York, and for now tonight’s game is on as planned. But stay tuned in case things take a turn for the worse.

It’s “UK-US Friendship Day” at Nationals Park, with Prime Minister Rishi Sunak scheduled to attend what I can only assume will be the first Major League Baseball game he’s ever seen in person.

The Nationals are trying to snap a three-game losing streak, and to do that they’ll need a better all-around pitching performance, beginning with starter Patrick Corbin, who faces his former team. Corbin’s last outing came one week ago at Dodger Stadium, where he trailed 3-0 after three batters, but ultimately made it through five innings allowing only one more (unearned) run. The Nats would really like a more effective, and longer, start from the lefty tonight.

The bullpen has another new face. For the second straight day, the Nationals designated a struggling reliever for assignment, with Erasmo Ramírez the victim this time following a ragged appearance Tuesday night. Cory Abbott was recalled from Triple-A Rochester, where he was originally scheduled to start tonight. If Corbin doesn’t go deep and Davey Martinez needs multiple innings from a reliever, Abbott is probably the guy.

The sting of the Nationals’ 10-5 loss to the Diamondbacks still loomed over the entire home clubhouse Tuesday night, but Stone Garrett couldn’t help but light up when asked about the grand slam he clubbed way back in the first inning off a team and a pitcher he knew all too well.

“It felt freaking good,” the 27-year-old said, his smile growing wide. “That’s my best friend pitching. And your old team. Keibert (Ruiz) just hit two home runs off his old team (last week at Dodger Stadium), so it feels good. Revenge game.”

Designated for assignment by Arizona last November, then signed by the Nats two weeks later, Garrett already faced his former team last month at Chase Field. And he already faced Tommy Henry, the 25-year-old left-hander who became one of his closest friends and a regular roommate through their respective treks up the organizational ladder.

This, though, meant far more. With the bases loaded in the bottom of the first, Garrett launched a changeup from his good buddy deep to left, the ball clearing the fence for the first grand slam of his career and the first grand slam by any Nationals player at home since Yan Gomes on June 15, 2021.

“It felt like a good pitch,” Henry told reporters in the visitors’ clubhouse. “Yeah, it’s unfortunate it was him. It’s unfortunate in any circumstance, but unfortunate it was him because I probably won’t hear the end of it now.”

For the second straight game, Davey Martinez pulled a struggling starter in the middle innings and entrusted a struggling reliever to keep a close game against a quality opponent close.

And for the second straight game, that struggling reliever not only couldn’t keep the game close, he couldn’t even keep it close enough for his Nationals teammates to have a realistic shot at coming back by night’s end.

Jake Irvin was tonight’s fading starter, and Erasmo Ramirez was tonight’s struggling reliever. They bore a striking resemblance to Trevor Williams and Andrés Machado from two days prior in a loss to the Phillies. In this case, the opponent was the Diamondbacks, who took full advantage of the Nats’ pitching woes during a 10-5 victory that further underscored some major problems for the home club.

"Walks," an unusually and visibly aggravated Martinez lamented. "We're walking too many guys. Hitting batters. Falling behind. Pitching 2-0, 1-0, 3-1. You're not going to win very many games like that. We've got to clean that up."

The Nationals have now lost six of their last eight, and a recurring theme throughout this stretch has been ragged relief pitching, whether in the middle or late innings. The situation already was dire entering the day, with the Nats owning the National League’s worst bullpen ERA (4.73) and WHIP (1.433), and things only got worse.

The Nationals made the first of what could be several moves in coming days to address a bullpen that has become the roster’s weakest link, designating Andrés Machado for assignment and recalling Jordan Weems from Triple-A Rochester.

Machado, who was tagged for four runs and gave up a pair of killer homers during Sunday’s loss to the Phillies, was out of options and couldn’t be demoted to the minor leagues without first clearing waivers. The Nationals will wait to see if the 30-year-old clears, but because he already went through this process last winter he’ll have the right to refuse an outright assignment to Triple-A and could elect to become a free agent instead.

A somewhat consistently effective bullpen arm for the Nationals in 2021-22, Machado had a 3.41 ERA and 1.326 WHIP across 91 appearances. But after opening this season in Rochester and making his return to the majors in late April, he struggled. In 14 games, he finished with an 8.47 ERA and 1.765 WHIP.

“It’s a tough move,” manager Davey Martinez said. “I really like Machado, and he’s got good stuff. It’s just his location was not good, and he was getting hit really hard.”

A Nats bullpen that performed well in 2022 and entered this season as a perceived strength has instead turned into a major cause for concern. The group enters tonight’s game against the Diamondbacks with a National League-worst 4.73 ERA and 1.433 WHIP.

The Nationals and Diamondbacks engaged in a highly entertaining series one month ago in Phoenix, the D-backs ultimately winning two of the three games (though one only after storming back to win in the bottom of the ninth). Now the surprise National League West leaders come to D.C. for a three-game series against a Nats club that continues to compete but would like to emerge victorious a few more times against quality opponents.

Jake Irvin gets the start, the seventh of his young career. The rookie right-hander showed some glimpses of improvement last time out against the Dodgers but still wound up allowing four runs in five innings to that potent lineup. The Nationals could sure use a solid start out of Irvin, whose spot in the rotation isn’t necessarily on thin ice, but it isn’t exactly solid either.

The Nats face yet another left-hander in Tommy Henry, who held them to two runs in six innings last month at Chase Field, both runs scoring on a Keibert Ruiz double. As noted here before, these guys have fared much better against lefties this season than righties, so here’s a chance to keep that trend going and provide Irvin with some run support.

As expected, there’s a bullpen roster move today: Andrés Machado was indeed designated for assignment following Sunday’s rough outing. Right-hander Jordan Weems was recalled from Triple-A Rochester to take his spot. So the Nats remain without any left-handed relievers for now.

The notion that Stephen Strasburg might still come back to pitch for the Nationals again, sadly, seemed to pass months ago.

When manager Davey Martinez revealed on the first day of spring training Strasburg was unable to complete an offseason bullpen session without a recurrence of the nerve pain that has plagued him for several years, the writing was on the wall.

And when general manager Mike Rizzo said on Opening Day the 34-year-old needed to rehab his injury “if nothing more, just to play with his children, get back to regular life,” it underscored the severity of the situation, far beyond anything that takes place on a baseball field.

Strasburg has not appeared at Nationals Park this season during the hours leading up to, during or after a home game. His locker remains where it has always been, his jersey and belongings neatly arranged, essentially untouched. Teammates he barely knows walk past it every day, with little reason to think about the pitcher whose name hangs above it.

Strasburg isn’t currently participating in any rehabilitation activities, as The Washington Post reported over the weekend. He resides on the 60-day injured list, technically still a part of the team but not on anybody’s immediate radar.

It was an eventful week for the Nationals. It started in Los Angeles with three competitive games at Dodger Stadium, capped by an impressive, five-homer performance in a series-closing victory. It ended in D.C. with three competitive games at Nationals Park, capped by an unfortunate, five-homer performance by the Phillies in a series-closing victory.

Now, with an off-day heading into another home series against the Diamondbacks, let's take a moment to discuss everything that has happened, on and off the field of late. (And, yes, that includes the Stephen Strasburg situation, if you're interested.)

Submit your questions in the comments section below, then check back throughout the morning for my responses ...

The entire weekend seemed to have been building up to this moment, with Kyle Schwarber stepping to the plate for the Phillies in a big spot in a close ballgame and Davey Martinez left to decide which of his Nationals pitchers to entrust against the veteran slugger.

Martinez’s options with two on and two out in the top of the sixth this afternoon were Trevor Williams, who had already thrown 101 pitches and was attempting to complete six innings for only the third time in 12 starts this year, or a member of his bullpen.

It should’ve been an easy call. Just walk toward the mound, stick out your left arm and tap it a couple times with your right hand.

The problem: The Nationals don’t have any left-handers in their eight-man bullpen. They haven’t had one since April 30, when Anthony Banda (owner of a 6.43 ERA) was designated for assignment.

Martinez has been left to tempt fate for the last five weeks, hoping his various right-handers can get the job done against the league’s best lefty sluggers. Sometimes, it’s worked out fine. Today, it turned into disaster.

CJ Abrams is starting to get more regular days off as Nationals manager Davey Martinez tries to give his young shortstop more opportunities to rest his body and mind in his first full big league season.

Abrams, who started 31 of the Nats’ first 32 games this season, is not in the lineup for today’s series finale against the Phillies. It’s the fifth time he hasn’t started in the team’s last 27 games. It’s also the second straight Sunday he’s had off.

“Just kind of let him relax a little bit,” Martinez said.

It’s been an eventful stretch for Abrams, who played a key role in recent road wins in Kansas City and Los Angeles but also committed three errors in his last five games, a couple of them particularly costly ones.

With the team off Monday, this gives Abrams a chance for an extended rest before he returns to the lineup Tuesday night against the Diamondbacks.

Saturday’s 4-2 loss was disappointing, sure, but it wasn’t embarrassing. The Nationals just didn’t hit as much as the Phillies did, so they lost the game. And they still have a chance to win the series and enter the week tied with the defending National League champs in the standings. Who wouldn’t have taken that scenario if presented with it from the outset?

The Nats will hope to get their bats back on track while facing Ranger Suárez, a potentially advantageous matchup. They’ve hit left-handers well all season and enter today’s game with an impressive .292/.358/.426 slash line, that .784 OPS good enough to rank eighth in the majors against southpaws. Suárez, who season debut was delayed by an elbow strain, enters with a 7.13 ERA and 1.642 WHIP in four starts, though his last one (two runs in 6 2/3 innings against the Mets) was good.

Trevor Williams gets the ball for the Nationals, looking to rebound from his weirdest start of the season, one in which he carried a shutout into the fifth inning at Dodger Stadium but then surrendered six runs, all of them unearned. He’ll have to keep Kyle Schwarber, Bryce Harper, Trea Turner and Nick Castellanos in the yard today, maybe helped out by an unusually cool, northerly breeze that will be blowing in from left field.

MacKenzie Gore is working on a lot of things in his first season with the Nationals. He’s only 24 years old and now only has 28 games of major league experience under his belt.

One thing the left-hander really wants to improve on is getting left-handed batters out.

“I should get left-handers out,” Gore said after yesterday’s 4-2 loss to the Phillies. “Left-handers don't like hitting left-handed pitching.”

So far in his young career, Gore is a reverse-splits pitcher. Coming into yesterday’s start, he had surrendered a .293/.429/.453 slash line with a .881 OPS and 1.23 strikeout-per-walk rate against left-handed batters. He had given up a slash line of .235/.312/.370 with a .683 OPS and 2.92 K/BB rate to righties.

Is he surprised that he had reverse splits?

The Nationals were in position today to be somewhere they haven’t been since April 3: Anywhere but last place in the National League East.

Last night’s dramatic 8-7 victory gave them the same record as the defending National League champion Phillies, who also happen to be in town this weekend. A win today would have put them ahead of them in the division standings.

With an electric young pitcher in MacKenzie Gore on the mound and a lineup that’s been heating up facing a group of relievers, the Nats had a good chance to vault out of the basement. But after scoring 18 runs over their last two games, the offense cooled down and wasn’t able to produce enough in a 4-2 loss in front of an announced crowd of 30,959.

“We just couldn't get the offense going today," manager Davey Martinez said after the game. "I thought MacKenzie threw the ball well. Made a couple of mistakes, but other than that he was around the zone all day and gave us a good six innings. Just the bats were stale today.”

After one of the best outings of his young career, Gore was able to turn in back-to-back quality starts for the first time since late April.

Last night’s wild 8-7 win was significant for the Nationals in that it brought them into a tie with the defending National League champion Phillies in the division standings.

Davey Martinez, always focused on going 1-0 every single day, managed in a way to give the Nats the best opportunity to come away with a series-opening victory. Put your best stuff out there today and worry about tomorrow later.

Well, tomorrow is today, and there are some possible ramifications from last night’s game.

Martinez deployed his “A” bullpen last night after starter Josiah Gray couldn’t get out of the sixth inning. Carl Edwards Jr. (20 pitches), Hunter Harvey (16), Mason Thompson (11) and Kyle Finnegan (34) all threw a decent amount and in high-leverage situations.

Finnegan, whose pitch count set a new career high, is probably unavailable today, as the Nats try to jump the Phillies in the National League East. But the rest of the bullpen may be available to pitch in some capacity if needed, assuming their pregame work goes well.

For the first time since mid-April, the Nationals will have a chance to stand alone outside the basement of the National League East. And for the second straight game, the Nationals’ future will be on display against its past.

MacKenzie Gore gets his first shot at former Nats Bryce Harper, Trea Turner and Kyle Schwarber as a National. He did face each of them over his 16 appearances with the Padres last year: Harper went 0-for-3 with a strikeout; Turner went 2-for-2 with an RBI double and was hit by a pitch; and Schwarber went 0-for-3 with two strikeouts and a walk.

Gore is coming off a career-high 11 strikeouts in seven innings of one-run ball on Sunday against the Royals. On the year, the lefty is 3-3 with a 3.57 ERA, 1.414 WHIP and 11.5 strikeout-per-nine-innings rate.

Left-hander Matt Strahm is starting a bullpen game for the Phillies this afternoon. He’s 4-3 with a 3.20 ERA and 1.042 WHIP in 15 appearances (seven starts) this season. Strahm is expected to go at least two innings for manager Rob Thomson, who had to use four relievers last night after Zack Wheeler couldn’t get out of the fourth.

Kyle Finnegan returned to the dugout after getting out of the top of the eighth Friday night, having surrendered the tying run to the Phillies (albeit an unearned run due to CJ Abrams’ throwing error) and having thrown 13 pitches.

Davey Martinez tried to tell Finnegan his night was done. The right-hander insisted it was not.

“I just felt like I had some more in me, and I wanted to empty the tank,” Finnegan said. “It was a good, hard-fought game, and I felt like I could go out there and get some more outs for us.”

So Martinez let Finnegan go back to pitch the ninth, understanding he wouldn’t let him go beyond his pre-designated limit of 35 pitches for his late-inning relievers.

Finnegan wound up finishing the game, securing the Nationals’ 8-7 win over the Phillies, on 34 pitches.
