Irvin averaged 91.4 mph with his fastball during Wednesday's Grapefruit League start against the Cardinals, down significantly from the 93.8 mph he averaged in 2024, but he said after the game he felt fine, Mark Zuckerman of MASN Sports reports.

EDGE Analysis

The Nationals allowed the right-hander to build up to 91 pitches (64 strikes), so even though the results weren't pretty -- six runs allowed on 10 hits, including two home runs, over 5.2 innings -- the team would seem to share Irvin's confidence in his fitness. "No, we would've definitely taken him out [if we thought he was dealing with a health issue]," manager Dave Martinez said after the game. "But he said he felt great. He said nothing to worry about. He's tinkering. One, he's throwing the slider, he's throwing the cutter, so his fastball was just a little off." Irvin had been pitching fairly well this spring prior to the blowup, and he still has a 3.86 ERA through 16.1 innings after Wednesday, albeit with a lackluster 9:8 K:BB. He's expected to get one more turn during the exhibition schedule before starting the second game of the season for the Nats on March 29 against the Phillies.

Irvin gave up six runs (one earned) on four hits and three walks over 3.1 innings during Sunday's Grapefruit League game against the Mets. He struck out three.

EDGE Analysis

Some shaky defense behind the right-hander got Irvin off the hook for some earned runs during a six-run first inning by New York, but most of the damage came on homers by Mark Vientos and Jakson Reetz. Irvin was still able to build up to 81 pitches (48 strikes), and the 28-year-old remains on track to begin the season in the Nationals' rotation despite his disconcerting 5:6 K:BB through 10.2 spring innings.

Irvin tossed a perfect inning in Saturday's Grapefruit League game against the Astros.

EDGE Analysis

The 28-year-old right-hander needed only eight pitches to breeze through his first game action of the spring. Per Mark Zuckerman of MASN Sports, one of those eight pitches was a slider, an offering Irvin is trying to add to his arsenal in an effort to get more whiffs. "I struggled a lot with getting in-zone swing and miss last year," Irvin said after Saturday's outing. "[The slider] is something that will kind of balance out the really slower curveball and the harder fastball. And then my cutter and changeup are both a little harder, too. I wanted something that's in that middle ground there." Irvin posted a 4.41 ERA, 1.20 WHIP and 156:52 K:BB over a career-high 187.2 innings in 2024.

Irvin (10-14) took the loss Sunday against the Phillies, allowing six earned runs on five hits and three walks in 4.1 innings. He struck out three.

EDGE Analysis

Irvin stumbled out of the gates, allowing the bases to be loaded with zero out in the opening frame. He managed to limit the damage to two runs by inducing a pair of fielders choices, but Irvin ran into trouble again in the fifth inning. The right-hander loaded the bases with zero out, allowing a pair of runs to score on a Kyle Schwarber single and later a Weston Wilson double, giving the Phillies a 6-1 advantage. The 27-year-old Irvin finishes his second professional campaign with a respectable 4.41 ERA, 1.20 WHIP and 156:52 K:BB in 187.2 innings (33 starts). Irvin will look to improve his consistency next season after he limped to the finish line in 2024, pitching to a 5.90 ERA, 1.34 WHIP and 57:23 K:BB in 71.2 post All-Star break innings.

Irvin (10-13) allowed five runs on four hits and four walks while striking out three over four innings to take the loss Sunday versus the Cubs.

EDGE Analysis

Irvin yielded three home runs, which accounted for four of the five runs he surrendered. He's struggled with the Cubs both times he's faced them this year, allowing 12 runs over 8.2 innings in those starts. Irvin is now at a 4.22 ERA, 1.18 WHIP and 153:49 K:BB across 183.1 innings through 32 starts. His last start of the season is projected to be at home versus the Phillies.

Irvin came away with a no-decision in Monday's 2-1 extra-inning loss to the Mets, allowing one run on four hits and a walk through 7.1 innings. He struck out five.

EDGE Analysis

The righty put together his second straight quality start and 16th of the season on 94 pitches (65 strikes), and Irvin took a shutout into the eighth inning before New York finally broke through. Irvin has had a bumpy finish to the campaign, giving up at least four runs in five of nine outings since the beginning of August while posting a 5.65 ERA, 1.37 WHIP and 39:15 K:BB through 51 innings. He'll look to keep rolling in his next start, which lines up to come on the road this weekend against the Cubs.

Irvin (10-12) earned the win over Atlanta on Wednesday, allowing one run on two hits and one walk while striking out five batters over six innings.

EDGE Analysis

Irvin retired the first 10 batters he faced and was working on a no-hitter until Atlanta finally got to him for consecutive doubles in the sixth inning. The right-hander emerged with his first quality start since Aug. 13, which was also the date of his most recent win prior to Wednesday. Irvin had been struggling prior to this excellent outing, as he had surrendered 13 runs across 9.2 frames in his previous two starts. He's fallen off in the second half after a strong beginning to the campaign, but he still has 10 wins and a tolerable 4.19 ERA overall.

Irvin (9-12) was saddled with the loss Thursday, allowing six runs on seven hits and three walks over five innings against the Pirates. He struck out four.

EDGE Analysis

Irvin was staked to an early three-run lead but gave up a five spot in the second as he allowed three walks and four singles as the Pirates sent 10 men to the plate. It was the second-consecutive outing Irvin allowed 10 batters to reach base while allowing 13 runs over 9.2 innings during his last two starts, raising his ERA nearly a half run from 3.80 to 4.28. Irvin will look to pull things back together during his next start, currently slated to take place in a home matchup against Atlanta.

Irvin (9-11) yielded seven runs on eight hits and two walks over 4.2 innings Friday, striking out six and taking a loss against the Cubs.

EDGE Analysis

Irvin fell apart in the second inning, coughing up all seven runs in the disastrous frame. It was capped off by Cody Bellinger's two-run blast. Irvin gave up five or more runs just once in his first 18 starts but has done so four times in his last 10 appearances. During that 10-start stretch, he's registered a 6.55 ERA, driving his season ERA up to 4.08 through 161 innings. Irvin's next outing is projected to be in Pittsburgh.

Irvin did not factor into the decision in Saturday's loss to Atlanta, allowing two runs on five hits and three walks over 5.1 innings while striking out three.

EDGE Analysis

Irvin allowed the leadoff man to reach in each of the first two innings to open the contest but managed to escape without allowing any damage on both occasions. However, the lack of command would catch up with the right-hander as he went on to surrender a solo shot to Orlando Arcia on a hanging slider in the fifth before then giving up back-to-back hits to open the sixth. Irvin was then relieved by Robert Garcia with no outs in the frame, who would also proceed to allow back-tb-back hits. The 27-year-old has given up multiple runs in nine consecutive starts, going 2-4 over that stretch while posting a 5.92 ERA. Irvin has also served up at least one long ball in four consecutive outings.
