SAN FRANCISCO – There were moments tonight when the Nationals seemed to be on Logan Webb. They did, after all, rap out nine hits off the Giants ace and present themselves with a number of golden opportunities in the early innings at Oracle Park.

And then there were moments tonight when it seemed like Webb had the Nats eating out of his hand. Especially when facing the inexperienced bottom of this lineup, which was no match for the right-hander’s assortment of sinkers, changeups and sliders.

In the end, there were more of those frustrating moments than the promising ones for the Nationals, who managed only one run off Webb and were left to suffer a 4-1 loss to San Francisco in the second game of this week’s series by the bay.

Continuing a semi-recurring theme through the season’s first six weeks, the Nats hit a bunch of singles to give themselves a chance. But they could not take advantage of those opportunities, going 1-for-12 with runners in scoring position, including 0-for-7 in the game’s first three innings alone.

"We had traffic all day; we couldn't get that big hit," manager Davey Martinez said. "(Webb) got tough. Guys were on base, he threw some really good changeups, mixed in his two-seamer. He got really tough with guys on base."

SAN FRANCISCO – Though they aren’t making any declarations about the long-term plan with Jake Irvin, the Nationals aren’t about to remove the rookie right-hander from the rotation after his dominant performance Monday night.

Irvin, who shut out the Giants over 6 1/3 impressive innings, will at least take his next turn in the rotation, which should come up Sunday against the Mets at Nationals Park.

“As of right now, I would say he’ll get that start again,” manager Davey Martinez said. “I think he’s earned that. And then after that, we’ll see where we’re at.”

Martinez was careful not to pronounce any plans beyond that, but with Chad Kuhl still making his way back from a foot injury, the job appears to be Irvin’s for at least a while longer.

The Nationals’ biggest concern with Irvin may not be his performance but his workload. After missing the 2021 season following Tommy John surgery, he was held to 103 1/3 innings over 24 minor league starts last year.

SAN FRANCISCO – Don’t look now, but the Nationals have won 10 of their last 17. They’re 15-20 overall. They’re one game behind the Phillies, 1 1/2 games behind the Marlins, two games behind the Mets. Sure, it’s still early May, and there’s a whole lot that can still go wrong (or right), but this is unquestionably a better position than almost anyone envisioned this team being in at this moment.

The Nats will look to keep the good vibes rolling tonight in the middle game of this series against the Giants, hoping Patrick Corbin can pick up where he left off last time out. In far and away his best start in a long time, Corbin carried a one-hit shutout into the eighth inning against the Cubs before finally fading. He did so by pounding the strike zone, tunneling his fastball and slider to make them look the same coming out of his hand and keeping the opposing hitters off balance.

The Nationals would love to give Corbin an early lead like they did for Jake Irvin on Monday night. They’ll see what they can do against veteran Giants right-hander Logan Webb, trotting out the same lineup as the series opener with one notable exception: Jake Alu makes his major league debut, batting ninth and starting in left field.

SAN FRANCISCO – Hits are coming in bunches for Luis García right now. The Nationals will happily take them from their young second baseman.

With a 2-for-5 showing Monday night during the Nats’ 5-1 win over the Giants, García continued a torrid week at the plate. He’s now 10-for-18 on this West Coast road trip, having produced multiple hits in each of the team’s four games to date.

García’s offensive surge has actually been going on longer than that, though. On the morning of April 27, he sported a weak .209/.260/.328 slash line, leaving him with a paltry .589 OPS. In 12 games since, he has slashed a robust .378/.408/.556, raising his season OPS to .739. That actually ranks tops among all active regulars in the Nationals lineup through 35 games.

What changed?

“I changed a little bit; I raised my hands a little bit, and that’s helped,” García said, via interpreter Octavio Martinez. “But to be honest, I think it’s just the work. Putting in the work to maintain my focus out there every at-bat. I’m going to keep working and keep my focus the same as it’s always out there on every at-bat.”

SAN FRANCISCO – Jake Irvin took the mound at Oracle Park tonight, already the proud recipient of a five-run lead thanks to a sudden barrage of hits from his teammates in the top of the first, and went to work. With a purpose.

Irvin worked fast. He threw strikes. He changed speeds. He bounced off the mound every time he recorded a strikeout or induced a double play.

And the rookie right-hander did it all as well as anyone else who has taken the mound wearing a Nationals uniform so far this season. And better than anyone who has ever taken the mound wearing a curly W cap with so little experience under his belt.

With a crisp, 6 1/3 innings of scoreless ball, Irvin mowed down the Giants lineup. And thanks to that early barrage from his teammates against opposing starter Anthony DeSclafani, the Nats rewarded him with his first career win in a 5-1 game that saw the Nats score all of their runs in the top of the first.

In a game that required a scant 2 hours, 14 minutes to be completed, the Nationals improved to 14-14 since a ragged 1-6 opening week to the season. They did it tonight behind a most unlikely pitching prodigy in Irvin, who in his second major league start looked every bit like an established veteran who had a plan to beat an opposing lineup and executed it to perfection.

SAN FRANCISCO – Victor Robles officially went on the 10-day injured list with back spasms today, leaving the Nationals without their starting center fielder and leaving the club with only three true outfielders for now.

Robles hurt himself sliding into second base on a stolen base attempt Saturday night in Arizona. He sat out Sunday’s game, and because it didn’t appear he’d be ready to return in short order the club decided to place him on the IL and bring in another healthy position player.

“He came in today, got treatment, still feeling the same,” manager Davey Martinez said. “I’m sure it’s going to take him a few days before he really feels better, and then we’ll go from there.”

The healthy player added is Jake Alu, the 26-year-old utility man who was promoted from Triple-A Rochester and will be making his major league debut once he steps on the field. Alu, who was batting .247 with four doubles, two homers and 10 RBIs in 21 games for Rochester, is a natural infielder who has been seeing some action in the outfield as he tries to prep himself for a potential career as a versatile bench player in the big leagues.

With only three true outfielders – Stone Garrett, Alex Call, Lane Thomas – on the active roster now, Martinez will have to get creative. Martinez said Call will be the starting center fielder in Robles’ absence, with Thomas remaining in right field. Garrett is starting in left field tonight, but Joey Meneses, Ildemaro Vargas and Alu all could see time there as well until the rest of the roster gets healthy.

SAN FRANCISCO – After a wild weekend in Arizona, what’s in store for the Nationals here in San Francisco? Oracle Park isn’t exactly a home run haven, so they may not want to count on hitting ninth-inning bombs again this week. But with all the room out there in the gaps, this could be a big series for doubles and triples.

Jake Irvin takes the ball for his second career start, having acquitted himself well in his debut against the Cubs. Irvin will need to be a bit more efficient this time around and try to avoid the four walks he issued last time out. He would also do well not to plunk the Giants’ leadoff man on his very first pitch.

The Nationals go up against veteran right-hander Anthony DeSclafani, who has been quite good so far this season. He enters 3-1 with a 2.13 ERA and a ridiculous 30-to-3 strikeout-to-walk ratio in six starts. He tossed eight scoreless innings in Houston last time out, which of course is no small feat.

As Davey Martinez revealed after Sunday’s game, the Nats have made a roster move: Victor Robles officially was placed on the 10-day injured list today with back spasms, with utility man Jake Alu promoted from Triple-A Rochester for the first time in his career. With Robles sidelined, expect to see a lot of Alex Call in center field and Stone Garrett in left field, but we’ll see if Alu or Ildemaro Vargas get any time in the outfield as well.

PHOENIX – The message from Bryan Harvey was already on his son’s phone, waiting for him when he arrived back in the Nationals clubhouse following Sunday’s dramatic, 9-8 win over the Diamondbacks.

“He already texted me and said I’m 176 behind him,” Hunter Harvey said with a laugh.

It’s a message Bryan Harvey surely had been waiting to send for years, and one Hunter Harvey had been waiting to receive for years. Though he was originally drafted by the Orioles a decade ago as a starter, injuries derailed the right-hander’s chances of making it to the majors in that role.

Harvey became a full-time reliever in 2019, profiling as an obvious future closer because of his ability to throw a baseball 100 mph. But not until Sunday did he actually find himself on the mound in the ninth inning with his team leading by three or fewer runs.

Harvey found himself in that spot because Kyle Finnegan had blown the save Saturday night, giving up a game-tying homer and then walking in the winning run during his fourth appearance in five days. With Finnegan unavailable Sunday due to that heavy workload, manager Davey Martinez opted to give Harvey the opportunity to notch his first career save, should the situation arise.

PHOENIX – The way it happened Saturday night, with a five-run rally in the top of the ninth wiped out by disaster in the bottom of the ninth, it felt like a soul-crushing development for the Nationals. The kind of loss that sits with a team for days.

That does not, however, appear to be the character of this particular team. Because when presented with an opportunity to do the exact same thing this afternoon at Chase Field, the Nationals once again stormed back, getting a titanic, three-run homer from Joey Meneses in the top of the ninth to take the lead.

And this time, they turned to Hunter Harvey to close out a scintillating, 9-8 victory over the Diamondbacks.

"These guys have got a bunch of heart," manager Davey Martinez said. "They're playing together. They feel like they're never out of it, and today's another good example. They fought back and put up some big numbers again."

Taking over for Kyle Finnegan as closer, at least for the day, Harvey pitched a scoreless bottom of the ninth to secure the win and the long-awaited first save of his injury-plagued career.

PHOENIX – The Nationals don’t have either Victor Robles or Jeimer Candelario in their lineup for today’s series finale against the Diamondbacks, the former dealing with a stiff back that knocked him out of Saturday night’s game, the latter still recovering from the bout of dehydration that landed him in the hospital Friday night.

Robles hurt himself sliding into second base on a stolen base attempt in the third inning Saturday, though he remained in the game until the following inning when Alex Call stepped in to pinch-hit for him.

Manager Davey Martinez didn’t want to take a chance putting Robles right back in the lineup today, not wanting to let a back issue get any worse for a player who runs as much as the speedy center fielder does.

“It’s definitely going to be a little bit of a concern, because of the way he plays the game,” Martinez said. “He came in here, he got treatment, he’s going to get some more treatment. We’ll keep an eye on him, and hopefully it gets better. And if it doesn’t, we’ll have to think about something else, maybe another day. I’ll talk to the trainers throughout the day and see how he’s doing.”

Candelario began to feel poor late during Friday’s game, then felt “weird” while he was showering after the game. He was treated by paramedics and was taken to a local hospital for overnight evaluation, but doctors ruled anything more serious than dehydration.

PHOENIX – The Nationals once again find themselves needing to win a series finale to avoid a three-game sweep. This is the fifth time already this season it’s happened, but the good news is they’re 3-1 in such matchups, having beaten the Braves, Guardians and Pirates. Only the ridiculously hot Rays managed to pull off a three-game sweep against them.

So they’ll try to make it 4-1 this afternoon when they face the Diamondbacks one last time at Chase Field, this time with the roof closed. The dry air has been good for a power-starved lineup: Luis García, Keibert Ruiz and Lane Thomas have all homered in this series. Unfortunately, Arizona also has hit three homers, including Lourdes Gurriel Jr.’s game-tying blast to lead off the bottom of the ninth Saturday night.

We’ll have to see if Kyle Finnegan is used as closer again today, should the situation present itself. Davey Martinez certainly has an easy out if he wants to sit Finnegan, citing the four games in five days he has pitched. Would he instead go to Hunter Harvey, who has had two days off after pitching back-to-back-to-back days, for his first career save? Stay tuned.

Trevor Williams gets the start, and the right-hander will be looking to pick up right where he left off Tuesday night when he tossed 5 1/3 scoreless innings against the Cubs at Nationals Park. He’s opposed by Diamondbacks right-hander Ryne Nelson, who in six starts this season owns a 6.39 ERA and 1.516 WHIP.

PHOENIX – A lot happened during Saturday night’s game, a wild 8-7 loss to the Diamondbacks. The Nationals got nine strikeouts from MacKenzie Gore in six innings. They pulled off a five-run rally in the top of the ninth, four of those runs scoring with two outs. They gave it back in the bottom of the ninth when Kyle Finnegan retired only one of the six batters he faced.

There were other developments of note, as well. And those shouldn’t be ignored as you process everything that took place in this highly eventful ballgame …

* Keibert Ruiz snapped out of his slump in a big way.

The young catcher insisted Friday night he wouldn’t hang his head after striking out three times and seeing his slump extend to 0-for-16. He made good on that promise Saturday, delivering a two-run double in the fourth and then a towering homer to lead off the ninth.

These were important swings for Ruiz. Not simply because of the results, but because of the authority with which he connected for those hits. His double carried an exit velocity of 106.4 mph. His homer was actually a bit lower, at 104.7 mph. He even made loud contact on a second-inning groundout to short, a ball that left his bat at 99.7 mph.

PHOENIX – This looked like one of those nights when the Nationals would be left to focus on the positives that emerged from a nondescript loss. Most notably, an ace-like performance from MacKenzie Gore.

Then this looked like one of those nights when the Nationals would celebrate a stunning victory thanks to the five runs they scored in the top of the ninth behind the offensive exploits of Keibert Ruiz, Ildemaro Vargas and Lane Thomas.

But at the end of a wild Saturday night in the desert, all the Nats could do was trudge off the field having suffered their toughest loss of the season, falling to the Diamondbacks, 8-7, after Kyle Finnegan blew an unexpected save opportunity in the bottom of the ninth in agonizing fashion.

"I can't say enough about what our team did, behind like that and coming back," manager Davey Martinez said. "It shows a lot of fight. It shows a lot of the character of our ballclub. And you've got a team over there that's fighting back. Look, we made it a battle. At the end, we couldn't hold the lead."

Entrusted with a one-run lead thanks to his teammates' shocking rally in the top of the inning, Finnegan immediately gave it back on Lourdes Gurriel Jr.'s leadoff homer to left. Despite the pleas of Stone Garrett that a fan reached over the fence to interfere with his play, league officials in New York upheld the home run call, leaving the game tied.

PHOENIX – Jeimer Candelario spent Friday night in a hospital following the Nationals’ game with what doctors ultimately determined was a bout of dehydration.

Candelario appeared to feel fine throughout the game, according to manager Davey Martinez, but shortly after the 3-1 loss to the Diamondbacks felt dizzy and was taken to the trainer’s room at Chase Field to wait for paramedics to arrive. After receiving IV fluids, the 29-year-old third baseman was taken to a nearby hospital for precautionary tests, but was released today once any serious issues were ruled out.

“He went and took a shower, said he didn’t feel well,” Martinez said. “They laid him down. He started shaking pretty good. They came in, we saw a doctor and he deemed he was dehydrated. They gave him some fluids, and he still didn’t feel right. We just wanted to make sure we got him all checked out. Everything checked out.”

It wasn’t particularly warm Friday night, with a gametime temperature of only 79 degrees, but dehydration isn’t uncommon in the desert. Candelario went 1-for-3 with a strikeout and was in the on-deck circle when Joey Meneses struck out to end the game.

Candelario was kept out of tonight’s lineup. It’s the first time he has sat this season; he had been the only player on the team to start each of the Nationals’ 32 games to date.

PHOENIX – Would you believe every run the Nationals have scored the last two days came on a home run? It’s true. Now, they’ve only scored five total runs in that time, and they did so via three homers (Lane Thomas’ three-run blast, Alex Call’s walk-off, Luis Garcia’s solo shot). But this team that typically scores only via singles and doubles hasn’t done so since Wednesday.

They’ll try to change that reversal of fortunes tonight, hoping for more success against the plate against the Diamondbacks’ Tommy Henry than they had against Merrill Kelly in the series opener. Henry, a 25-year-old lefty, is making his 12th big league starts. Through his first 11, he owns a 5.56, 1.482 WHIP and a very low 1.54 strikeout-to-walk ratio. Suffice it to say, this should be a pitcher the Nats can have some success against. (Key word: should.)

It may not take a whole lot of offense to emerge victorious tonight, if MacKenzie Gore can return to form after struggling his last start. The left-hander gave up four runs on seven hits and needed 102 pitches just to record 12 outs against the Cubs, an uncharacteristic performance. Gore intended to work on some things during the week. We’ll see if he’s able to put that into practice tonight against the Arizona lineup.

PHOENIX – Keibert Ruiz has dealt with slumps before. That’s not new. But he hasn’t dealt with one in which the simple act of making contact has become such a challenge.

Nobody on the Nationals roster, and hardly anyone in the majors, is better at putting the bat on the ball than Ruiz, whose 95 percent contact rate on pitches in the strike zone is among the best in the sport.

So when he struck out in his first three at-bats during Friday night’s 3-1 loss to the Diamondbacks, it was notable and unusual. This was only the third time in Ruiz’s career he struck out thrice in one game. And when you add his final at-bat Thursday against the Cubs, he actually endured through a streak of four consecutive plate appearances with a strikeout.

“I just don’t feel like I was feeling like I was a couple days ago,” he said. “I’m not using my legs, not using the same approach. I need to go back to keeping it simple and not try to do too much.”

Ruiz was hardly alone in struggling against Diamondbacks starter Merrill Kelly, who struck out 10 over seven dominant innings. But his struggles were the least characteristic, given his usual ability to make contact.

PHOENIX – Even on an unseasonably cool, 79-degree evening in these parts, the ball always flies well at Chase Field, especially when the roof and outfield panels are open. A power-starved Nationals lineup took the field tonight hoping to take advantage of that in its series opener against the Diamondbacks and throughout the weekend.

Alas, one must actually make contact to have a chance to hit the ball out of any park. And on this night against Merrill Kelly, that seemingly simple task proved far too difficult for the Nats.

Behind a 10-strikeout performance from their right-hander, the Diamondbacks emerged victorious, 3-1, the Nationals once again unable to provide much run support for star-crossed starter Josiah Gray.

Gray wasn’t in peak form tonight, allowing three runs over five innings. But he would’ve needed to be perfect to best Kelly, who had the Nats eating out of his hand.

Even Keibert Ruiz, the best contact hitter on the team and one of the best in the majors, couldn’t get the bat on the ball. The young catcher struck out in all three of his plate appearances against Kelly, his first three-strikeout game this season and only the third of his career.

PHOENIX – Hunter Harvey understands why people will immediately make the connection, believing he blew the Nationals’ 3-0 lead in the eighth inning Thursday because he was pitching for the third straight day for the first time in his career.

The Nationals reliever insists there was no connection between those two facts.

“No, I don’t think it had anything to do with being the third day,” he said. “I just didn’t execute. That could happen when you’re fresh or when you’re not fresh.”

Harvey had already pitched Tuesday, recording five big outs on 21 pitches to help lead the Nationals to victory over the Cubs. He had also pitched Wednesday, tossing a scoreless eighth on 14 pitches to preserve his team’s 2-1 lead and eventual victory.

Through it all, the 28-year-old right-hander felt strong. And when it came time to inform manager Davey Martinez about his availability for Thursday’s game, he didn’t hesitate to offer his services if the situation called for it.

PHOENIX – Hello from the Valley of the Sun, where the temperature is only topping out in the 80s this weekend. Which means the roof at Chase Field will be open both tonight and Saturday. Around here, that’s a huge win.

Speaking of huge wins, the Nationals are coming off a big one over the Cubs to cap a solid homestand. They’ll try to keep their winning ways alive on the road, where they’ve been a much better team so far this season.

The good news: They’ve got Josiah Gray on the mound for tonight’s series opener against the Diamondbacks. The bad news: They almost certainly don’t have either Hunter Harvey or Kyle Finnegan in their bullpen after those guys each pitched the last three days. Quality innings from Gray will be key tonight, and then someone else from Davey Martinez’s bullpen will have to close it out.

A lineup that started to show signs of power back home will hope for more of that in the warm, dry air here. This has always been a good hitter’s park, and it’s even more so when the roof is open. The Nats will try to hit some balls in the air tonight against Arizona right-hander Merrill Kelly.

With two on and nobody out in the top of the ninth Wednesday night, Kyle Finnegan’s thoughts hearkened back 12 days prior, when he faced an identical situation and lived to tell about that.

That cold night in Minnesota, Finnegan pitched his way out of a jam by getting a lineout and then a 5-4-3 double play, preserving a one-run victory for the Nationals. This time, he pulled it off thanks to a fielder’s choice on a bunt, then a 6-4-3 double play, preserving another one-run victory.

“I found myself there a couple times before this year,” Finnegan said. “Knowing that I’ve gotten out of it before helps a lot. And we’ve been turning so many double plays behind us, you know you’re never really out of it.”

Look at Finnegan’s 2023 totals to date, and it’s easy to believe he’s having a disastrous season. His ERA is 6.00. His WHIP is 1.583. He has surrendered three homers in only 12 innings.

That doesn’t accurately reflect his true performance to date, though. Most of those lofty numbers were the direct result of one awful appearance on April 4 against the Rays, when he was roughed up for five runs while recording only one out, surrendering all three of those homers.
