Sewald earned a save against the Tigers on Monday, striking out one batter in a perfect inning of work.

It didn't look like there would be any save opportunities after Arizona built an 8-0 lead through five frames, but Detroit made a late rally to get close. Sewald was summoned to protect a three-run lead in the ninth frame, and he avoided any drama by retiring the side in order on 12 pitches. Manager Torey Lovullo previously hinted that Sewald might be the favorite for early save chances, and that became a firmer scenario given Monday's bullpen usage. Sewald certainly has plenty of experience in the role, having racked up 81 regular-season saves between 2021 and 2024.

Walker earned a save against the Padres on Monday, allowing two runs on one hit and one walk while striking out one batter over one inning.

Walker appeared to be in line for a relatively easy save when he entered with a 3-0 lead in the ninth inning, but the veteran reliever struggled to close things out. He issued an inning-opening walk and later served up a two-run blast to Jackson Merrill with two outs. Walker was ultimately able to end the game by getting Xander Bogaerts to ground out to shortstop. This was Walker's third appearance but first save chance of the season. Despite the uneven outing, he has a pretty strong hold on San Francisco's closer role for the time being.

Williams (1) earned the save Monday against the Cardinals, tossing a perfect ninth inning with one strikeout.

Williams entered the ninth with a two-run lead and only needed 12 pitches to shut the door, sealing the win by striking out Nathan Church for the final out. After a down 2025 campaign with the Yankees in which he posted a 4.79 ERA across 62 innings, Monday was an encouraging showing as the 31-year-old looks to return to dominance in his first year with the Mets.

Megill (0-1) allowed one run on one hit and one walk in Monday's 3-2 loss to the Rays. He struck out one.

Megill was brought on to open the top of the ninth of a 2-2 game and got Junior Caminero to ground out before striking out Ben Williamson. However, Megill walked Jonny DeLuca and then surrendered an RBI double to Nick Fortes. Megill appears to have a solid hold on the closer job for the Brewers after securing his first save of the season Sunday against the White Sox. After pitching back-to-back days, Megill is likely unavailable for Tuesday's game against Tampa Bay.

Leahy (0-1) took the loss Monday against the Mets, allowing four runs on eight hits and two walks while striking out one over five innings.

Making just his second MLB start, Leahy immediately found himself in trouble, giving up a leadoff triple to Francisco Lindor who eventually came around to score. The right-hander struggled to limit traffic all day, allowing at least one hit in every inning he pitched. While Leahy was able to work into the sixth frame throwing 79 pitches, the constant contact led to dangerous situations throughout the outing and four runs crossing the plate. After starting the final game of 2025, the 28-year-old is now adjusting to a rotation role and will look to find more consistency in his next outing against Detroit.

Holmes (1-0) earned the win against the Cardinals on Monday, allowing two runs on four hits and three walks while striking out five over 5.2 innings.

Holmes surrendered an early run in the first inning but settled in from there, shutting down St. Louis over the next four frames. The right-hander was one out away from a quality start before Nolan Gorman tagged him for a solo homer in the sixth, immediately ending his outing. Following this strong start to the season, the 33-year-old is lined up to face San Francisco in his next start, a favorable matchup given the Giants' offensive struggles so far in 2026.

Poulin will serve as the Nationals' opening pitcher for Tuesday's game against the Phillies, Mark Zuckerman of NatsJournal.com reports.

Poulin has appeared in two games so far this season, walking two and striking out one over 1.2 scoreless frames. He'll likely work the first inning before giving way to a primary pitcher, who the Nationals have yet to name. Zack Littell could be in the mix to eat up innings considering he's the only starter who's yet to see action in 2026.

Hentges (knee/shoulder) threw 20 pitches during his live batting practice in Arizona on Monday, Shayna Rubin of the San Francisco Chronicle reports.

Hentges continues to progress in his recovery from surgeries on his left shoulder and right knee. He opened the season on the 15-day injured list and will need to embark on a rehab assignment before being cleared for major-league action. The last time Hentges pitched in the majors was in 2024 with the Guardians, when he appeared in 25 regular-season games and posted a 3.04 ERA, 0.97 WHIP, nine holds and a 27:5 K:BB across 23.2 innings.

Adam (quadriceps) will throw a simulated game Tuesday before making back-to-back rehab appearances with Double-A San Antonio on Friday and Saturday, Jeff Sanders of The San Diego Union-Tribune reports.

Making rehab appearances on back-to-back days is typically the final hurdle a pitcher needs to clear before rejoining the major-league roster, so Adam appears set for activation from the 15-day injured list when first eligible April 6. The veteran reliever is getting a late start to the season following surgery last September to repair a ruptured left quadriceps tendon. Adam will work in a setup role in front of closer Mason Miller.

Schultz (elbow) struck out two and allowed no hits and one walk over 1.2 scoreless innings in his first rehab appearance Saturday for Triple-A Rochester.

The appearance was Schultz's first since Feb. 28, after he had missed the final three weeks of the Grapefruit League due to right elbow inflammation. The 28-year-old will likely make at least another rehab appearance or two before returning from the injured list. While the Nationals will likely use him in lower-leverage spots initially once he's activated, Schultz could quickly move his way into a more prominent role if he pitches well early on, given the lack of established options in the bullpen.
