Jeimer Candelario was sitting at his locker following Sunday’s game, phone in hand, watching the highlight of one of his defensive gems from the Nationals’ 4-1 win over the Braves, when reporters approached him.

Perhaps caught by surprise, Candelario quickly turned off the phone, as if he didn’t want anyone to know he was watching his own highlight reel. Not that anyone could blame him for wanting to bask in the glow following a spectacular game at third base.

“We knew that going in. We knew he was going to make plays,” said MacKenzie Gore, the pitcher who most directly benefitted from the stellar glove work. “We’re going to play good defense. We did that in the spring, and that’s what we did today. We had double plays. Candy was making plays all around. It was fun to watch.”

After a sloppy Opening Day and a less-than-crisp Game 2 to the season, the Nationals infield was flawless during Sunday’s win. They turned three double plays, including a critical 4-6-3 started by Luis Garcia to escape a sixth-inning jam. They saw Ildemaro Vargas, filling in for CJ Abrams at shortstop for the day, handle his three chances with no problems.

But most of all, they watched Candelario put on a dazzling show throughout the afternoon at third base.

MacKenzie Gore had been waiting for this, longer than he ever wanted. Same for the Nationals. And their fans, as well. From the moment the Nats and Padres consummated one of the biggest trades in baseball history, the notion of Gore making his D.C. debut had been front and center on many people’s minds. Alas, a bout of elbow inflammation delayed that debut until this afternoon.

At last, though, precisely eight months to the day since the trade that sent Juan Soto and Josh Bell to San Diego for a horde of prospects, the premier pitcher in the deal took the mound on South Capitol Street in a regular season game. And then delivered on the promise of what he could be for this franchise for years to come.

With 5 1/3 strong, at times dominant, innings against one of the toughest lineups in the majors, Gore led the Nationals to their first victory of 2023, a 4-1 triumph before an appreciative crowd of 21,440 that finally had reason to cheer for something positive and for someone with the potential to be a cornerstone of this roster rebuild.

"It's been a long time," the lefty said. "I've been looking forward to it. It was a lot of fun."

Gore allowed just one run on three hits. He struck out six. And though he walked four, he still managed to throw 60 percent of his pitches for strikes and show off the dazzling repertoire that has made him a top pitching prospect since the Padres drafted him third overall in 2017.

Though he won’t undergo an MRI until later today, Corey Dickerson was already placed on the 10-day injured list this morning by the Nationals, who couldn’t afford to wait for test results on their veteran left fielder’s left calf.

Needing another healthy outfielder on the active roster for today’s series finale against the Braves, the Nats called up Stone Garrett, who arrived from Triple-A Rochester this morning and reported straight to Nationals Park.

The team is calling Dickerson’s injury a left calf strain for now, pending results of his MRI. The 33-year-old told manager Davey Martinez he first felt tightness as he jogged off the field following the top of the seventh inning of Saturday’s 7-1 loss. Not wanting to take any chances, Martinez had utility man Ildemaro Vargas take over in left field for the final two innings of the game.

“I’d rather it be a shorter stint than try to push it and it becomes a bigger issue,” the manager said.

Dickerson, who signed a one-year, $2.25 million contract with the Nationals this winter, missed one month with a left calf strain last season while playing for the Cardinals.

It’s not particularly fair to MacKenzie Gore, who takes the mound today wearing a Nationals uniform for the first time in a regular season game. The left-hander shouldn’t have to deal with any added pressure in his long-awaited club debut. But make no mistake: The Nats really need him to pitch well.

When you drop the first two games of the season by a combined score of 14-3, you need to ask your Game 3 starter to put together a really nice outing. So the pressure most certainly is on Gore this afternoon against a tough Braves lineup that already torched Patrick Corbin and Josiah Gray.

Gore, one of the centerpiece young players the Nationals received from the Padres in the Juan Soto trade, was unable to pitch for his new team last year due to elbow inflammation. He did make it through the entire spring healthy, and looked quite sharp in his final Grapefruit League start against the Yankees. But as Gray can tell you, there’s a huge difference between spring training and the regular season. Gore will need to be in peak form today.

The Nats could certainly help their young starter out by providing him some early run support for a change. They’ll try to get something brewing against a pitcher none of them have seen before in the big leagues: Jared Shuster. The 24-year-old lefty (a first-round pick in the 2020 draft) makes his major league debut this afternoon; he struck out 145 batters in 139 1/3 minor-league innings last season.

It’s never a good idea to infer regular season performance based on spring training numbers, but in the case of Josiah Gray there seemed to be some valid reason to believe what he did in Florida in March could translate into what he would do in Washington in April.

Not the 0.55 ERA Gray posted in Grapefruit League play, as impressive as that looked. No, the primary reason the Nationals were excited about Gray entering his season debut today was the fact he issued only two walks and did not surrender a home run in 16 2/3 innings of exhibition baseball. Given how much of problem both were for the right-hander last year, this felt like a good omen.

Well, it did for all of six pitches this afternoon.

Back-to-back homers to open the game set an ominous tone for Gray, who would allow a third before departing after five roughshod innings during a 7-1 thrashing at the hands of the Braves.

Ronald Acuña Jr. and Matt Olson did the damage in the first two minutes of the first inning, leaving Gray shell-shocked and a still-arriving crowd of 27,529 wondering what exactly just happened.

Davey Martinez admitted this spring he might be trotting out different-looking lineups on a daily basis, based on matchups, lefty-righty splits and other assorted information. Whether the Nationals manager realized all along how different his Game 1 and Game 2 lineups would look is a valid question.

The lineup card Martinez submitted for this afternoon’s game against the Braves features eight of the same names that started on Opening Day, with only Corey Dickerson replacing Alex Call in left field. But only one of those eight players is actually batting in the same location: Joey Meneses, who again gets the No. 2 slot.

“We’re going to have to mix and match a little bit this year,” Martinez admitted during his pregame session with reporters. “The one thing I do like is having Joey in the 2-hole. Because if we do have someone that needs to get that last at-bat (in the ninth inning), I want to make sure he gets it.”

The most notable change from Thursday is at the top of the lineup. Luis García, who batted seventh in the opener, is leading off today, flip-flopping with Lane Thomas.

García did get several opportunities to lead off in spring training, and he also did it eight times last season. A notorious free-swinger who owns one of the lowest walk rates in the league, the 22-year-old doesn’t exactly profile as a typical leadoff man. Martinez, though, specifically liked him batting first today against Braves starter Spencer Strider.

There are few days on the baseball calendar as frustrating as the off-day following Opening Day. It’s unfortunately tradition, though, included to serve as a fallback option for the season opener in case of bad weather. When the weather’s fine, all it does is give everyone way too much time to overanalyze Game 1 before turning attention to Game 2.

The Nationals and Braves can finally focus on that next game now, with first pitch on South Capitol Street scheduled for 4:05 p.m. The Nats will hope to bounce back from a rough 7-2 loss that included bad defense, laborious starting pitching and very little clutch hitting.

Josiah Gray will have to be more efficient than Patrick Corbin was. The young right-hander was outstanding all spring, so he should enter this start with renewed confidence. But he’ll have to work really hard to keep the ball in the yard against a power-laden Braves lineup that will try to take advantage of a strong wind blowing straight out to center field once the rain clears out this afternoon.

The Nationals will hope some familiarity with Spencer Strider leads to some success. The flamethrowing right-hander made two starts in D.C. last summer. He dominated the first one, allowing one hit (a Luis García homer) while striking out 11 in 5 2/3 innings. But then the Nats got to him for five runs in four innings one month later, so perhaps they’ve got a better book on him now.

Bryce Harper was the first to coin the phrase, way back on Sept. 23, 2012 when the then-rookie outfielder lost a fly ball in the sun during an afternoon game at Nationals Park.

“You can’t catch what you can’t see, you know?” Harper said that day. “Nothing you can do about it. Sun Monster got me.”

And for the last decade, anyone who has closely watched the Nationals has known to beware the Sun Monster every September. He comes out like clockwork, just as the summer humidity dissipates and the afternoon sun moves into a lower position above the upper deck at the ballpark.

In Thursday’s season opener, though, the Sun Monster made an extremely rare, late-March appearance, wreaking as much havoc on players in the field for both the Nats and Braves as perhaps it ever has.

It happened during the Nationals’ very first plate appearance of the season. Lane Thomas’ top-of-the-first popup into shallow center field appeared to make for an easy catch for either shortstop Orlando Arcia or center fielder Michael Harris II. But when Arcia called off his teammate and reached up to make the play, he recoiled in horror when he couldn’t locate the ball, which landed harmlessly on the grass for a cheap single.

If there is going to be a semi-regular formula for the Nationals to win ballgames in 2023, it will almost certainly have to include clean defense from a revamped infield, quality pitching from a deep bullpen and timely hitting from a lineup that hits for contact better than for power.

Maybe they can pull out some curly Ws when they achieve two of those three goals. But to expect it when they only get one of them right? That’s a tall ask, as they learned this afternoon.

Despite hanging around with the defending division champions until things fell apart in the ninth, the Nationals were left to accept a 7-2 Opening Day loss to the Braves that was defined by sloppy defense and a lack of clutch hitting.

"I could tell you now, they were a little bit nervous," manager Davey Martinez said of his relatively inexperienced team. "I was a little nervous. It's part of it."

Three errors by shortstop CJ Abrams proved costly, as did a 1-for-11 showing by Nats hitters with runners in scoring position. Those combined to undermine a strong showing by the bullpen, which churned out five scoreless innings after a laboring Patrick Corbin was pulled in the top of the fourth, with only Kyle Finnegan faltering during a three-run top of the ninth that turned a close game lopsided.

In setting their Opening Day roster this morning, the Nationals officially placed six players on the injured list, including Stephen Strasburg.

Strasburg (thoracic outlet syndrome), Cade Cavalli (Tommy John surgery), Tanner Rainey (Tommy John surgery) and Victor Arano (right shoulder strain) all were placed on the 60-day IL. Those moves cleared up four spots on the 40-man roster, which went to the four players who made the club off minor-league deals: Chad Kuhl, Michael Chavis, Anthony Banda and Hobie Harris.

Carter Kieboom (right shoulder impingement) and Israel Pineda (right finger fracture) were placed on the 10-day IL, though neither is expected to be ready to return in such little time. Kieboom, who is still coming back from Tommy John surgery last year, has only been able to DH in minor league spring games. Pineda, who was struck by a foul ball in early March, has resumed throwing but was not yet hitting when camp concluded.

Though Strasburg’s inclusion on the 60-day IL was no surprise, the transaction does underscore the right-hander’s current predicament. Unable to throw off a mound without discomfort since making his one and only start last season, he is currently not participating in any baseball activities.

General manager Mike Rizzo said he met in person Wednesday with Strasburg, whose locker remains full of gear even though he was not present at spring training and won’t be at the ballpark for the season opener.

It’s a beautiful (if a bit chilly) day for baseball in the nation’s capital, where the 2023 season begins when the Nationals take the field shortly after 1 p.m. to host the Braves. This is expected to be another long season featuring far more losses than wins, but if you can’t be optimistic on Opening Day, what’s the point?

The Nats had all kinds of trouble against the Braves last season, going 5-14 while being outscored 116-67. (To be fair, they had all kinds of trouble with everyone from the National League East last season.) Patrick Corbin in particular was awful in his four matchups with them, going 0-3 with a 9.42 ERA and 2.372 WHIP. Oof. Suffice it to say, the veteran left-hander has his hands full this afternoon. His goal: Go as far as he can, and just keep his team in the game.

On the bright side, the Nationals did have some modest success against Max Fried last season, scoring 10 runs on 20 hits over 18 innings vs. the Atlanta left-hander. They'll hope to continue some of that this afternoon with a new-look lineup that isn't heavy on power but does have some contact and speed to work with.

It was a routine chopper back to the pitcher, the kind of play that’s made 99.5 percent of the time. Knowing that, CJ Abrams slowed down as he approached first base, assuming he would easily be thrown out.

Except when A.J. Minter’s throw sailed high, and Braves first baseman Matt Olson had to dive back to tag the base with his glove, Abrams lack of hustle cost him and the Nationals. Had he run hard all the way through the bag, he would’ve been safe at a critical moment in the eighth inning of what was a tie game. Instead, he had to make the walk of shame back to the dugout, where a perturbed Davey Martinez was waiting.

“That can’t happen,” Abrams said afterward. “I talked to Davey about it. Won’t happen again, for sure.”

It was a potentially low moment for the rookie shortstop, but two innings later he made sure it wouldn’t be his most memorable play from Wednesday night’s game. With a two-out RBI single to right in the bottom of the 10th, Abrams delivered the first walk-off hit of his career, sending the Nationals to a 3-2 victory and leaving the 21-year-old to be mobbed by teammates.

“It was good for him, especially after the baserunning thing,” Martinez said. “He comes back, he puts it aside and he gets after that at-bat and gets a big base hit for us. It’s good to see that. He stayed in the game, stayed poised.”

The Nationals have any number of reasons to want to finish this 100-plus-loss season on positive notes, both on a team level and an individual level.

On a team level, the 3-2 10-inning win they pulled off tonight over the Braves thanks to CJ Abrams’ walk-off single most definitely qualifies as a positive note.

On an individual level, the six standout innings Josiah Gray pitched tonight most definitely does as well.

With his best start in more than a month, Gray nearly shut down the Braves’ potent lineup altogether, allowing Matt Olson’s solo homer in the second but hardly anything else during an 85-pitch gem during what might wind up being his final start of an up-and-down year.

That decision is still to come from Davey Martinez, who has repeatedly mentioned a desire to limit the 24-year-old’s innings and potentially shut him down early, but to date has continued to let him take the mound up to the season’s final week.

The Nationals have their final scheduled off-day of the season Thursday. After which they’re hoping to play their final seven games in six days as planned.

The problem: Nobody knows at this point if it will possible to play all seven of those games in time due to a dismal weather forecast.

As Hurricane Ian made landfall today on Florida’s Gulf Coast, attention understandably has been on those communities now dealing with dangerous wind and flooding. But the remnants of the Category 4 storm could wreak havoc with the entire East Coast in the coming days, and that would have a direct impact on multiple series that need to be played to determine the National League pennant race.

The Nationals are scheduled to host the Phillies for four games in three days, with a Saturday doubleheader in the middle, while the Mets face the Braves in Atlanta for three games. Then the Nats head to New York to finish the season with three games at Citi Field, where weather still could be an issue Monday.

For now, Friday looks like the best day of the weekend here in Washington, with Saturday the worst and Sunday potentially somewhat better. Given that, the Nationals and Phillies are waiting to hear from Major League Baseball about the possibility of the Saturday doubleheader being moved to Friday, in the hopes they could at least get two games played before the worst of the storm arrives.

It hasn’t been a pleasant experience for the Nationals to face the Braves this season. (Not that it’s been much more pleasant to face anybody else in the NL East this season.) Tonight, they get one final shot at beating the defending World Series champions and perhaps dealing them a blow in their attempt to surpass the Mets to win the division this year.

It’s Josiah Gray back on the mound for what again could be his final start of 2022, though there still remains a need for somebody to pitch next week’s final series in New York, so don’t just assume this is the end of the road. Regardless, the 24-year-old right-hander would love to wrap things up on a positive note, because it’s been a difficult September for him (18 earned runs, 25 hits, 11 walks, five homers in 19 1/3 innings).

Gray has actually faced the Braves only once this season, way back on April 13 at Truist Park. He tossed five scoreless innings, allowing only one hit. A lot, of course, has changed since then.

Jake Odorizzi starts for Atlanta. The Nats saw him this spring when he was with the Astros, but this is the first time they’ve faced him since he was acquired by the Braves. Davey Martinez goes with a lineup that again includes CJ Abrams as No. 2 hitter, with Luis García returning to play second base after sitting out Tuesday’s game and Riley Adams back behind the plate.

The first question posed to Davey Martinez following Tuesday night’s 8-2 loss to the Braves was about Paolo Espino, who once again cruised through an opposing lineup for three innings before collapsing once he had to face that lineup a second time.

The Nationals manager immediately pivoted to what he believed was the biggest reason for this loss: His team’s poor play in the field.

“I mean, we gave them six extra outs,” Martinez said. “We played two extra innings on defense.”

To be sure, this was the Nats’ worst defensive game in a while. There was only one official error (on a poor throw by shortstop CJ Abrams) but there were several more substandard moments in the field, from a couple of casual (and thus, late) throws by second baseman Cesar Hernandez and third baseman Ildemaro Vargas, plus a misplayed grounder by Espino that helped keep the top of the fourth alive and ultimately set the stage for Atlanta to score two runs.

It was tough to watch at times, but it was a reminder just how much better the Nationals have been in the field for weeks now.

The Nationals have legitimately been getting quality work from a deep stable of relievers for months now, helping keep far more games close than was the case during the season’s first half. And that includes several relievers capable of going multiple innings and posting multiple zeros.

If only they didn’t have to keep asking a couple of those relievers to start games and extend themselves beyond the point where they remain effective.

A lack of reliable (or healthy) starters has left the Nats in this position, needing to keep giving starts to the likes of Paolo Espino and Cory Abbott, who might be good for two or three innings but haven’t been able to sustain that success beyond that point.

It happened again tonight to Espino during an 8-2 loss to the Braves. After retiring the first 10 batters he faced, the right-hander retired only six of the last 11 he faced before, in the process failing to earn his long-coveted first win of the season.

Espino and those who followed him out of the bullpen weren’t helped a ton by their infield defense, which played its sloppiest game in a while.

MacKenzie Gore was back in the clubhouse at Nationals Park this afternoon, back from his fourth rehab start with Triple-A Rochester, fully acknowledging the outcome from his most recent start (six runs, six hits, three homers allowed in 3 2/3 innings) didn’t look great on paper.

“It’s tough. You look at the line last night, it looks like a bad outing,” the left-hander said. “But it’s really just the fourth that was bad.”

Indeed, a closer examination of Gore’s start against Worcester confirms all his troubles came in his final inning of work. When he walked off the mound at the end of the third, he had allowed only one of the 10 batters he had faced to that point to reach (a leadoff homer in the second). He had three strikeouts. He threw 27 of 39 pitches for strikes.

The fourth inning, though, was a mess for Gore. He issued his lone walk of the night. He gave up five extra-base hits, two of them homers. He threw only 18 of 33 pitches for strikes. And he was pulled before completing the inning, his total pitch count up to 72.

“I feel fine. I just haven’t built up as quickly as I thought I would,” he said. “The first three innings were good. The fourth, I just kind of ran out of gas.”

The disparity between the Nationals and Braves has been on display all year long when these two teams face each other. The Nats are 4-13 against Atlanta in 2022, and while there are multiple reasons for that, it’s hard to ignore this fact: They’ve been out-homered by the staggering total of 38 to 14. That disparity only increased Monday night, when the Braves hit three more home runs during an 8-0 shutout victory in which both teams finished with six hits.

This is all to make the point that the Nationals might want to try to break out the power bats tonight against Kyle Muller, called up by the Braves from Triple-A Gwinnett to start this game. The Nats faced the lefty once last season, scoring three runs in 4 2/3 innings off him. He’s made only two big league starts this season, producing a 10.57 ERA.

If the Nationals can score some runs, perhaps Paolo Espino can deliver five solid innings, keep Atlanta in the ballpark and put himself in position to finally earn his first win of the year. This is Espino’s fourth start (fifth overall appearance) against the Braves this season, and he’s allowed 11 runs (nine earned) on 20 hits in 16 1/3 innings.

The Nationals are nowhere near the pennant race this season. They enter the week an astounding 41 games back in the National League East, the largest deficit in club history.

But make no mistake, the Nats will play a significant role in determining who wins the division and who qualifies for the postseason as a wild card, because they’re about to play the majority of their remaining games against those teams.

There are 16 games left on the schedule, 13 of which come against the Braves, Phillies and Mets. It begins tonight with a three-game series at Atlanta. Then, following a three-game respite in Miami, the Nationals host the Braves for three and the Phillies for four in the final homestand of 2022 before finishing the year with a three-game series at New York.

What’s at stake? For the Mets and Braves, a division title. For the Phillies, a chance to end an 11-year playoff drought.

In the only truly close division race in the majors right now, the Mets hold a one-game advantage on the Braves (though they’re tied in the loss column, with Atlanta having two more games than New York still to play). Both have dominated the Nationals this season – the Braves are 10-3, the Mets are 11-5 – but the Nats haven’t faced Atlanta since the All-Star break.
