In 17 seasons since Major League Baseball returned to Washington, the number of Nationals players who have been booed by home fans can possibly be counted on one hand. It’s just not a regular occurrence in these parts.

The number of players from the 2019 World Series roster that have ever been booed? Well, that number stood at zero until 7:53 p.m. tonight, when Patrick Corbin handed the ball over to Davey Martinez and made the long walk back to the dugout having just surrendered seven runs in 1 2/3 tortured innings to set the tone in what would end up a 7-1 loss to the Giants.

A crowd of 23,751, many of whom probably stood behind Corbin throughout his struggles in 2020, 2021 and his first three starts in 2022, finally decided not to hold back any longer. It wasn’t a thunderous round of boos from everyone in attendance – that was reserved for a questionable upholding of a third inning call that saw Juan Soto ruled out trying to stretch a double off the wall into a triple – but neither was it a smattering of boos from a few rogue individuals.

This was the moment those fans chose to voice their displeasure for Corbin, who may have won Game 7 in Houston with three scoreless innings of relief but since that glorious October night 2 1/2 years ago has been unequivocally the worst starting pitcher in baseball.

Corbin has now made 46 starts over the last three seasons. He has delivered 26 losses, most in the majors. He has produced a 5.81 ERA, highest in the majors. And he has compiled a 1.554 WHIP, worst in the majors by a longshot.

When Hunter Harvey first felt what he described as a cramp in his right forearm during Wednesday night’s relief appearance, he knew he now faced a serious dilemma. Should he let the Nationals know he might be hurt, or should he try to pitch through it, knowing he was quickly establishing himself as one of the more trusted members of Davey Martinez’s bullpen only two weeks after joining the club?

Throughout his career with the Orioles, Harvey tended to keep these things to himself. That got him nowhere, aside from the injured list, usually for months at a time.

This time, he decided to speak up immediately. And though he’s now on the 10-day IL with a right pronator strain, he believes the stint will be brief because it’s being addressed now and not later.

“I’ve had too many times where I’ve felt stuff like this that I told them: ‘I think I can pitch with it; I don’t think it would be a problem,’ ” Harvey said. “But I’ve pitched with stuff like this before, and I’ll start doing something different trying to protect it and then I’ll end up blowing something out.”

Martinez certainly appreciated Harvey’s willingness to be forthcoming with his injury, an approach plenty of players in his position wouldn’t take.

After a disappointing finish to their four-game series with the Diamondbacks, the Nationals tonight open a three-game weekend set with the Giants. The defending National League West champs are off to a strong 8-5 start, though they did just lose three of four to the Mets at Citi Field.

The Nats are still figuring out their pitching plans for Saturday and Sunday. Some of those plans may depend on how things go tonight. If Patrick Corbin can give them quality innings, they can probably save Paolo Espino to make a spot start Saturday. If Corbin gets knocked out early, Davey Martinez may have to use Espino out of the bullpen tonight, and that would probably require a roster move before Saturday’s game.

The Giants are using their own spot starter this evening: Left-hander Sam Long. He’s made three relief appearances, totaling 2 2/3 scoreless innings. Five of his 12 outings last year came as a starter, but it doesn’t appear he’s stretched out to go very far tonight.

Davey Martinez knew this might happen. He’d been through a condensed, three-week spring training in 1995 following the end of the players’ strike, and he remembered the physical damage that caused, on pitchers in particular, once the season began later than originally planned.

So the last thing Martinez is right now is surprised. He had a hunch some pitchers wouldn’t be ready for the regular season grind after the short camp. And wouldn’t you know what happened?

First it was right-hander Mason Thompson, who landed on the 10-day injured list April 10 with biceps tendinitis. Then came the back-to-back blows this week: Sean Doolittle, who sprained his left elbow ligament, followed by Hunter Harvey, who has a pronator strain in his right forearm.

“When I went through this as a player in ’95, (for) a lot of these pitchers, April was pretty strenuous,” Martinez said. “I don’t know if it’s anything related to the short spring training, but you’ve got to look at (that), trying to ramp these guys up. That being said, this is the reason we tried to have so many different options, in case something like this would happen.”

Thompson pitched twice in the season’s first three days before he was placed on the IL. Doolittle pitched in six of the Nats’ first 12 games before telling club officials about the elbow pain that was growing worse. And Harvey, who pitched four times in 10 days after he was called up from Triple-A Rochester, reported physical issues following Wednesday night’s game. By Thursday afternoon, he joined the others on the IL.

When it finally came down to it early this evening, when the Nationals finally gave themselves a chance to complete a late rally and pull off an inspiring comeback against the Diamondbacks, they were handed a best-case scenario.

Bottom of the ninth, two outs, bases loaded, down by a run, Juan Soto at the plate. What more could you ask for?

"I'll take my chances with Juan up there with the bases loaded," manager Davey Martinez said. "I hope he gets up there a lot with the bases loaded."

Soto had come up with the bases full only once this season. RBI opportunities have been few and far between for perhaps the most feared hitter in baseball. So when this one presented itself, he was understandably motivated to deliver.

Alas, it takes more than motivation to deliver the hit that turns loss into victory. And when Soto popped up the high 0-2 cutter he saw from Arizona closer Mark Melancon, the dismay among the crowd of 14,424 and among the players in home white uniforms as a 4-3 loss became official was all too evident.

The Nationals were relieved to learn Josh Bell could return to today’s lineup after departing Wednesday night’s game with tightness in his left knee. They were not so relieved to learn another member of their bullpen is out with an arm ailment.

The Nats placed Hunter Harvey on the 10-day injured list shortly before today’s series finale against the Diamondbacks with a right pronator strain, a situation that appears to have just emerged within the last 24 hours after the hard-throwing reliever tossed a scoreless inning.

Harvey, the former Orioles first-round pick whose career has been beset by a smorgasbord of injuries, made four scoreless appearances since joining the Nationals bullpen during the season’s opening weekend. The 27-year-old was starting to earn his way into manager Davey Martinez’s good graces and perhaps start getting called upon in high-leverage situations, but something apparently didn’t feel right during Wednesday night’s game.

Harvey entered that outing averaging 97 mph on his fastball in his first three appearances. That number went down to 96 mph during Wednesday’s game, bottoming out at 94.3 mph on one of the 12 pitches he threw to three Arizona batters.

The pronator is part of the flexor mass group of muscles and tendons in the forearm, near the elbow. A pronator strain would be to one of the muscles in that area, not an uncommon injury for pitchers.

The Nationals have a chance to win a series this afternoon. If they can beat the Diamondbacks, they will have taken three of four and will improve to 7-8 on the young season. All things considered, that wouldn’t be bad at all.

As we’ve seen time and again, and as we certainly saw Wednesday night, the starting pitcher will probably have as much impact on the final outcome as anyone. The Nats continue to win when they get five or more quality innings from their starter (aside from one game, Sunday in Pittsburgh). They continue to lose when they don’t get that.

So, Josh Rogers: What do you have for us today? The lefty was outstanding in his season debut in Atlanta, then struggled his next start against the Pirates. He needs to get ahead in the count today, avoid walks and induce some weak contact out of an admittedly weak-hitting Diamondbacks lineup.

Here's some good news: Josh Bell is in the lineup, the MRI on his left knee having come back clean. Bell, who came out of Wednesday's game in the fourth inning, tested it out pregame and was cleared to play first base and bat cleanup as usual.

There was, however, another roster move before today's game: The Nationals have placed reliever Hunter Harvey on the 10-day injured list with a right pronator strain and selected the contract of fellow right-hander Erasmo Ramirez from Triple-A Rochester. (They transferred Ehire Adrianza to the 60-day IL to clear a spot on the 40-man roster.) So the bullpen, which already lost Sean Doolittle to an elbow sprain Wednesday, has now also lost Harvey for some period of time.

No injury is good news for any ballclub. But a Josh Bell injury would qualify as particularly damaging to the Nationals as currently constructed.

Bell, who departed Wednesday night’s game in the fourth inning with tightness in his left knee, is scheduled to undergo an MRI this morning. He was cautiously optimistic after the game it’s nothing serious, and described his departure from the game as “precautionary,” so there’s no need to panic yet.

That said, we got a glimpse of what the Nationals would look like minus Bell during the final six innings Wednesday, and it wasn’t pretty.

Maikel Franco moved from third base to first base. Lucius Fox came off the bench to take Franco’s spot at third base. That hurt the Nationals defensively, and it hurt them offensively. (The light-hitting Fox actually became their cleanup hitter in the process.)

Bell has been the only consistently productive bat in the lineup through the season’s first two weeks. His .977 OPS leads the club, and his 11 RBIs are tied for fifth in the majors. Remove him from the equation for any length of time, and the drop-off in production is staggering.

The day began with news of Sean Doolittle landing on the 10-day injured list with an elbow sprain, a development that on its own could’ve been enough to ruin the Nationals’ entire day.

Who knew it would be only the first in a series of calamities over the course of eight hours that ended with an 11-2 debacle of a loss to the Diamondbacks in which Erick Fedde recorded only 10 outs, Josh Bell departed with tightness in his left knee and a pregame demonstration of the U.S. Army parachute team prompted an emergency evacuation of the U.S. Capitol grounds.

Suffice it to say, it was not a particularly positive Wednesday night at the ballpark, wiping out plenty of the good vibes that emerged during Tuesday’s doubleheader sweep of Arizona.

"It felt like a cursed day, for sure, in that sense," Fedde said. "We're all trying to get our feet under us, and sometimes it's harder some days than others. I think we're all just trying to get through this first month and survive at this point."

This game represented a complete reversal of fortunes for both clubs. After holding the Diamondbacks to one total run across 18 innings of baseball the previous day, the Nationals pitching staff gave up a boatload of them tonight, with Fedde setting the tone during a start that lasted only 3 1/3 innings.

Sean Doolittle first felt something in his elbow during the seventh inning Sunday in Pittsburgh. It was sore, but nothing he hadn’t dealt with before. Then he warmed up Tuesday afternoon in the bullpen at Nationals Park, and it was worse. Still, he thought he could deal with it, so he pitched the top of the sixth in relief of Josiah Gray, retiring two of three batters faced but notably with his fastball velocity down a couple ticks.

By the time he returned to the dugout following that nine-pitch appearance, Doolittle realized he needed to speak up. He told the Nationals medical staff, which ordered an MRI. He left the team prior to the nightcap of the doubleheader against the Diamondbacks, and by night’s end the results were in: He has a sprained elbow ligament and has been placed on the 10-day injured list.

What exactly that means isn’t fully known yet. Doolittle said the MRI results are being sent to other doctors for further examination. He admits a ligament sprain can in some cases require major surgery. But that’s not part of the immediate plan for him. He’ll first attempt to rehab the injury and hope he can return to pitch in relatively short order.

“We don’t have a timetable. I know that sounds like I’m talking around it and talking in generalities, but we’ve got to let it tell us what’s going on,” the left-hander said. “So we’re going to throw ourselves into that process right now, starting today. I actually started last night. By the end of that 10 days, we’ll start throwing again, see where we’re at and go from there.”

Even if this proves to be a best-case scenario and Doolittle is able to resume throwing with no issues in the next couple weeks, today’s news is a significant blow to the Nationals and to the 35-year-old reliever, who five outings into his return to D.C. looked to be enjoying a career resurgence.

The Nationals seemed to get through Tuesday’s doubleheader in great shape, sweeping the Diamondbacks and holding them to one run over 18 innings. It may have come at a price, though, because there are roster changes today.

Sean Doolittle, who retired two of the three batters he faced in the sixth inning of Game 1, is going on the 10-day injured list with a sprained left elbow, which obviously is a concern. Sam Clay has been called up from Triple-A Rochester to take his spot. Additionally, the Nationals have kept lefty Francisco Perez (yesterday's 29th man for the doubleheader) in their bullpen and optioned Donovan Casey back to Rochester before the outfielder ever had a chance to make his major league debut.

So the roster looks a little different for tonight’s game, the third in this four-game series. The pressure will be on Erick Fedde to do what Josiah Gray and Joan Adon did Tuesday and provide quality innings, taking pressure off the bullpen. Fedde was solid in his last outing against the Pirates, allowing only two runs in five innings, but his pitch count of 96 was too high for Davey Martinez’s likes.

Davey Martinez’s last season as a big league player came in 2001, when he hit .287 for the Braves. Atlanta’s rotation, the backbone of a team that won 88 games to capture a division title, averaged 6.2 innings per start, tops in the National League. Even the worst rotation in the league that year, the Reds, averaged 5.4 innings per start.

On Tuesday night, Martinez watched Joan Adon become the first member of the Nationals rotation to complete six innings this season, then even record an out in the seventh before he was pulled. Not that they were alone in that regard: Ten other major league clubs had yet to get a six-inning start in 2022 as of Tuesday.

“The game has definitely changed,” Martinez said. “I look around at what’s going around the league. There’s only been like 10 or 11 games where starters have gone six innings. For someone that’s been doing this for three decades, the game has changed a lot.”

There are valid reasons for this. The condensed, three-week spring training is chief among them. Pitchers simply didn’t have the usual amount of time to build their arms up like they would during a camp that normally would’ve been twice as long.

But this is also a reflection of Major League Baseball in 2022, where length from starters simply isn’t viewed as the priority it once was. With teams having seen the data on starters facing a lineup three times a night, and with most bullpens featuring a bounty of big arms, front offices and field managers simply don’t believe it’s prudent to push most starters the way they used to.

The Nationals got what they needed in the first game of Tuesday’s doubleheader against the Diamondbacks. Josiah Gray pitched 5 ⅓ innings of one-run ball and four relievers combined to cover the remaining outs in a 6-1 win.

Would it be too much to ask for the same in the nightcap?

Joan Adon was hoping to get deep into the game to help out his taxed teammates in the bullpen and perhaps turn around his start to the season. The relievers who weren’t used in this afternoon’s game were hoping to post more zeros. And the Nationals offense was hoping to manufacture runs just like they had done earlier.

Adon did his part, becoming the first Nationals starting pitcher to complete six innings in 2022 as he helped his club complete the doubleheader sweep with a 1-0 win in front of an announced crowd of 11,720.

The 23-year-old rookie starter held the D-backs scoreless over 6 ⅓ innings with five strikeouts on 88 pitches, 57 for strikes, to earn his first major league win. A big turnaround from his previous two starts.

Let’s keep the ball rolling and play some more baseball!

The Nationals and Diamondbacks will shortly take the field again on South Capitol Street for tonight’s nightcap after Washington won the first game of today’s split doubleheader 6-1.

Joan Adon, on normal rest, is hoping his third time's the charm as he takes the mound tonight. The right-handed rookie is 0-2 with a 10.00 ERA over his first two starts of the season. In nine innings, he’s given up 13 hits, 10 runs, three home runs and seven walks (to just eight strikeouts) while hitting one batter and throwing three wild pitches.

Manager Davey Martinez elected to stick with Adon in this spot in an attempt to not put too much pressure on the already taxed bullpen in today’s twinbill. Martinez only used four relievers in the opener, so he should have plenty of options for the nightcap. The Nats will need another starter this weekend, but they will address that later in the week.

Left-hander Francisco Pérez has been designated as the 29th man to give the ‘pen some help for tonight’s game. He is only available for the nightcap because a 29th player is only eligible for both games of a doubleheader if both teams agree to it. The Diamondbacks are using 29th man on tonight's starter, Tyler Gilbert, so they didn’t need it for the first game.

A day-night doubleheader is no easy challenge for a major league manager, certainly not when it comes two weeks into a season in which no starting pitcher has completed six innings and no days off had been savored until Monday night’s scheduled series opener was rained out.

The Nationals, though, did just about everything they could this afternoon during a 6-1 victory over the Diamondbacks to make life easy on Davey Martinez.

They got a strong outing from Josiah Gray (one run in 5 1/3 innings). They got a key rally to take the lead. They got good work from a couple of their top relievers. And then they tacked on three late insurance runs, allowing closer Tanner Rainey to take a seat and Austin Voth to pitch the ninth instead.

Too bad more fans weren’t here to witness it. The announced paid attendance of 9,261 officially was the smallest in Nationals history (excluding 2021 games with COVID-19 capacity restrictions), though that number doesn’t include anyone who purchased a ticket to Monday night’s originally scheduled game and already exchanged it for a future game. (The previous low in club history was 10,999 on Sept. 20, 2010 against the Astros.)

Tiny gathering or not, those who did brave 47-degree temperatures and a strong wind out of the northwest were treated to a quality performance from the home team, which opened this 10-game homestand on a positive note.

When it came time to map out their pitching plans for today’s doubleheader, the Nationals had to consider multiple factors.

* Should they use regular starters Josiah Gray and Joan Adon, taking stress off their bullpen today but forcing them to find a fill-in starter later this week?

* Should they use one starter today and use their bullpen in the nightcap, saving Adon for Wednesday and keeping the rest of the rotation intact the rest of the week?

* Should they use their allotted 29th player for the doubleheader on a spot starter from Triple-A?

It’s a cold, windy Tuesday in the nation’s capital, but at least it’s not raining anymore. So guess what? Let’s play two!

Yes, we’ve got our first doubleheader of the season following the postponement of Monday night’s scheduled series opener between the Nationals and Diamondbacks. That game is being made up this afternoon at 1:05 p.m., with the originally scheduled 7:05 p.m. game still on tap for this evening.

Keep in mind all doubleheader games are once again scheduled for nine innings after two years of the seven-inning trial during the peak of the pandemic. That means pitching is of the essence, and the Nats will need to get length from their starters today.

With that in mind, Davey Martinez is sticking with both of his originally scheduled starters for the first two games of this series. It’s Josiah Gray in the afternoon game, then Joan Adon in the nightcap. They’ll have to find a spot starter sometime this weekend, likely Saturday, but they’ll delay that decision for now.

The season’s first two weeks have mostly been a blur. The Nationals played 11 games in 11 days, with multiple rain delays, one lighting delay, two road trips and a bunch of long nights along the way before finally getting a chance to catch their breath Monday.

That wasn’t even supposed to be a day off. If not for the persistent rain all day and night here, the Nats would’ve continued a stretch of 18 games in 18 days to begin the season, not getting their first scheduled day off until next Monday.

But since they did get a chance to hit the pause button for just a moment before it starts back up again with today’s doubleheader against the Diamondbacks, let’s take this moment to assess how things have gone so far.

Eleven games in, what have we learned about the 2022 Nationals?

* The rotation is shaky
This isn’t a surprise. It was the No. 1 area of concern entering the season. But now that we’ve seen two full turns of the rotation (plus Patrick Corbin a third time), we have actual evidence the concern was valid. Nats starters have a 5.80 ERA (fourth-worst in the majors) while averaging only 4.5 innings per outing. Nobody has completed six innings yet. There have been a handful of encouraging starts from Josiah Gray, Erick Fedde and Josh Rogers, but Corbin continues to struggle and Joan Adon looks very much like a rookie with minimal experience in the upper levels of the minors.

While the Nationals were an early rainout due to inclement weather forecasted for their series opener against the Diamondbacks, there was some news in the minor league system on Monday.

Luis García was named the International League Player of the Week for the week of April 11-17.

Optioned to Triple-A Rochester during the last week of spring training, García has been on a tear to start the season for the Red Wings. Over six games last week, the 21-year-old went 14-for-27 for a .519 batting average and 1.370 OPS while recording five extra-base hits, five RBIs and nine runs scored.

He's slashing .377/.411/.623 with an 1.034 OPS, two home runs, seven RBIs and three walks over 12 games to start the season at Rochester. In the field, he has played 10 games at shortstop (where he has committed four errors) and two games at second base.

In 110 career big league games between 2020-21, García slashed .254/.285/.395 with a .680 OPS, 24 doubles, two triples, six homers, 22 RBIs and 11 walks.

With rain in the forecast all afternoon and evening, the Nationals wasted little time making a call on tonight’s series opener against the Diamondbacks, announcing it has been postponed seven hours before scheduled first pitch.

The two teams will now play a split doubleheader Tuesday, with a new game starting at 1:05 p.m. ahead of the originally scheduled 7:05 p.m. nightcap. Both games will be nine innings, with Major League Baseball returning to longstanding rules after instituting seven-inning games for doubleheaders in 2020-21.

Fans holding tickets for tonight’s game can use them for the 1:05 p.m. game Tuesday or exchange them for tickets to an available future game. A separate ticket is required for the 7:05 p.m. game.

The rainout doesn’t necessarily come at a bad time for the Nationals, who just completed the first 11 games of a scheduled 18-day marathon with no breaks to open the season. With only two members of their rotation having even reached the sixth inning so far, the pitching staff has been taxed during a 4-7 opening stretch.

The Nats got home late Sunday night following a seven-game trip to Atlanta and Pittsburgh, having won two of three against the defending World Series champion Braves before dropping three of four to the Pirates.
