Perez gave up one run on one hit and two walks over one inning in the Marlins' Grapefruit League game against the Cardinals on Monday. He struck out one.

The 22-year-old right-hander tossed 19 pitches (nine strikes) in his first start of the spring before giving way to Max Meyer. Perez threw 118 innings across three levels in 2025, his first season back from Tommy John surgery, and while he scuffled early he posted a 3.86 ERA, 0.96 WHIP and 91:22 K:BB in 79.1 innings from July to the end of the regular season. The Marlins will let Perez ramp up slowly in camp, but he's locked into an Opening Day rotation spot.

Prielipp threw 1.2 scoreless innings with two strikeouts and three walks in his spring debut Monday. He's likely to remain a starter at Triple-A to start the season, considering the Twins signed three veteran left-handed relievers in the offseason, the Minneapolis Star Tribune reports.

He's a darkhorse candidate for the bullpen this spring given his arsenal, which includes a fastball that hit 97.5 mph during Monday's outing and a new slow curveball, according to Matthew Leach of MLB.com, to add to an off-speed mix that includes a slider and changeup. The 48th overall draft pick in 2022 had Tommy John surgery in 2021 and then needed internal brace surgery on the same elbow in July 2023. The Twins limited him to pitching less than five innings in any start last season until late September.

Sale agreed to a one-year, $27 million contract extension with Atlanta on Tuesday that includes a club option for $30 million in 2028, Jeff Passan of ESPN.com reports.

Sale was set to hit free agency after the season but will get some extra security with this deal. His fastball was up to 96 mph in his first spring action Sunday as he logged two scoreless innings.

Detmers allowed three runs on three hits and one walk while striking out one batter over 1.2 innings in a Cactus League start against Texas on Monday.

Detmers is being given the opportunity to return to the rotation this season, so his first appearance of the exhibition slate came as a starter. It didn't go well for the left-hander, however, as he fell behind 2-0 after two batters when Danny Jansen took him deep to left field. Detmers gave up another run later in the first inning and was pulled having recorded just two outs, but under spring-training rules, he returned for the top of the second and had a much better outcome, retiring all three batters he faced in that frame. Detmers was solid as a reliever last year and has shown flashes of brilliance as a starter in previous campaigns, so there's reason to hope he can stick in the Angels' rotation through the season despite Monday's rough spring showing.

Keller adjusted the grip on his changeup during the offseason, Kevin Gorman of the Pittsburgh Tribune-Review reports.

Keller throws a wide range of pitches and consistently tinkers with his offerings, though his changeup has never been a major part of his arsenal. It's unclear exactly how he changed the pitch, but he threw it six times in his spring debut Sunday against the Rays -- all against lefties. Keller reported feeling comfortable with the pitch, per Kevin Gorman of the Pittsburgh Tribune-Review, so it could be a more prominent part of Keller's game plan in 2026.

Povich allowed one hit and one walk in two scoreless innings during Monday's Grapefruit League game against Atlanta. He struck out one.

The Orioles have a quartet of arms battling for a roster spot this spring either as a sixth starter or bulk reliever, and Povich did his part Monday to keep himself under consideration. Zach Eflin (back) is expected to be a full participant at camp, though it remains to be seen when he'll make his spring debut. For now, Povich has Dean Kremer, Tyler Wells and Brandon Young as his primary competition.

Rasmussen allowed one hit in two scoreless innings during Monday's Grapefruit League game against Boston. He struck out three.

Rasmussen was very sharp in his first appearance of the spring, tossing 16 of his 23 pitches for strikes. Tampa Bay has already announced that Rasmussen is tabbed to start Opening Day, and the hope this season is that the Rays won't scale back his workload the way they did during the second half of last year. The right-hander should also benefit from the team moving back to pitcher-friendly Tropicana Field in 2026.

Skubal allowed two hits across two scoreless innings in Monday's Grapefruit League game against the Twins. He struck out four.

The reigning back-to-back American League Cy Young Award winner picked up where he left off last season as he breezed through two strong innings on 31 pitches. Skubal has already been named Detroit's Opening Day starter, so his workload will likely be closely managed the rest of spring training as he gears up for that contest. The southpaw is also scheduled to play for the United States in the World Baseball Classic, though he only plans on making one start during pool play next week before returning to camp, Jason Beck of MLB.com reports. That should leave Skubal fairly fresh heading into Opening Day after he made 31 regular-season starts each of the last two years.

Brown allowed two hits across two scoreless innings in Monday's Cactus League game against the Royals. He struck out three.

Making his spring debut, Brown looked sharp across his 30 pitches, 20 of which he tossed for strikes. The lanky righty spent time as both a starter and reliever last season, and he mostly struggled with a 5.92 ERA and 1.44 WHIP across 106.1 innings. However, Brown also struck out 121 batters and flashed a fastball that sat right around 96 mph, so there is plenty of upside in his arm. With the Cubs seemingly having a full rotation to begin the year, Brown figures to slot into the bullpen if he makes the team out of camp, though he could be an option to make some starts down the road if a need arises. As a reliever, the 26-year-old could see his stuff play up a bit.

Mautz is under consideration for a spot on the Cardinals' Opening Day roster in a relief or hybrid role, Derrick Goold of the St. Louis Post-Dispatch reports.

Mautz was added to the 40-man roster this offseason following a breakout year as a starter at Double-A Springfield, where he posted a 2.98 ERA, 1.11 WHIP and 134:33 K:BB over 114.2 innings. JoJo Romero is locked into one left-handed bullpen spot for the Cardinals, but he remains a trade candidate, and even if Romero stays put the team likely has at least one other lefty spot up for grabs. Mautz could fill that slot or be used in a hybrid role that would allow him to also make some spot starts. However, the most likely scenario is the southpaw opens the season in the Triple-A Memphis rotation to continue his development as a starting pitcher.
