Atlanta optioned Stratton to Triple-A Gwinnett on Sunday.

The right-hander finished 2025 in the big-league bullpen but is set to open the 2026 campaign back in the minors. Stratton made 15 appearances in the big leagues between Pittsburgh and Atlanta last year, posting a 5.21 ERA, 1.58 WHIP and 16:7 K:BB over 19 innings.

Atlanta reassigned Guerra to minor-league camp Sunday.

The 30-year-old righty reliever's removal from big-league camp comes as he's set to join Team Panama ahead of the World Baseball Classic. Guerra didn't make a strong case for a spot in Atlanta's Opening Day bullpen anyway after yielding five earned runs in 2.2 innings across three appearances in the Grapefruit League. He last appeared in the majors in 2023 and is likely to open the season in the Triple-A Gwinnett bullpen.

Sewald allowed one run on one hit and struck out one over one inning in Saturday's spring game against the Angels.

Sewald showed improved velocity in his Cactus League debut, which came in the fourth inning against some of the Angels expected starters. The 35-year-old reliever averaged 92 mph on the eight fastballs he threw, a couple of ticks up from the 90 mph he averaged in 2025 and more in line with the velocity he showed in his previous stint with the Diamondbacks. Sewald credited the improved velo to the work he put in at Driveline over the offseason, Alex Weiner of Arizona Sports reports. With Arizona having no set closer at this point in spring training, Sewald is in the mix for save opportunities along with Kevin Ginkel and Ryan Thompson.

Mlodzinski is competing for a spot in the Pirates' rotation, Kevin Gorman of the Pittsburgh Tribune-Review reports.

Mlodzinski is getting another chance to work as a starter, a role he held at the start of 2025 before shifting to the bullpen. He was more effective as a reliever, and the Pirates have a strong projected rotation with several depth options -- a combination that could ultimately lead Mlodzinski back to the bullpen to begin 2026. He's made one start so far this spring, striking out three while allowing only one hit across two shutout innings.

Garcia was taken out of Saturday's Cactus League game against the Angels due to an illness, Alex Weiner of ArizonaSports.com reports.

Garcia had diminished velocity and poor command over his pitches Saturday, but his performance turned out to be a symptom of illness rather than a physical injury. He'll take the time he needs to recover and should be back pitching in the Cactus League relatively soon.

Garcia was removed from Saturday's Cactus League game against the Angels with an apparent injury, Nick Piecoro of The Arizona Republic reports.

Garcia struggled with his command during his appearance Saturday, as he hit two batters and walked another before getting a visit from the training staff and exiting the game. It's unclear what exactly is bothering the 25-year-old lefty, but the team will take a closer look at him and likely offer an update after the game.

Williams is focused on adding a cutter and slider to his repertoire this season, Anthony DiComo of MLB.com reports.

The reliever known as the Airbender has been almost exclusively a fastball-changeup artist during his career, but a tough 2025 season with the Yankees in which he posted a career-worst 4.79 ERA, albeit with a much more palatable 2.68 FIP and 3.05 xERA, has Williams looking for an extra edge. The early results in spring training on the new pitches haven't exactly been encouraging -- Cardinals prospect JJ Wetherholt homered on a first-pitch cutter Friday -- but Williams isn't concerned. "That one specifically, I was just trying to throw a strike and he jumped on it," Williams said. "I kind of babied it, trying to just throw it over the plate. He wasn't giving me strike one." The 31-year-old right-hander is still going to lean heavily on his changeup to generate strikeouts, but having other options could help the Mets' new closer to rebound.

Lower-back tightness will limit Miller to throwing solely off flat ground for the next few days, Justice delos Santos of The San Jose Mercury News reports.

Miller's back has prevented him from pitching in the Cactus League, and he has yet to begin throwing off a mound. Assuming he doesn't encounter any setbacks, he's slated to begin throwing bullpen sessions sometime next week, but it's still unknown how far away he is from getting into a game.

Kerkering (hamstring) will throw a bullpen session Saturday, Charlotte Varnes of The Athletic reports.

It will be his first time throwing off a mound since he suffered a Grade 1 hamstring strain. If things go well Saturday, Kerkering would likely then progress to facing hitters before appearing in a game. The right-handed reliever has plenty of time to ramp up for Opening Day, barring setbacks.

The Dodgers signed Middleton to a minor-league contract Feb. 16.

Middleton made just five rehab appearances in 2024 before having flexor tendon surgery and then appeared in four games in 2025 with the Long Island Ducks of the independent Atlantic League. The 32-year-old pitched well in his last healthy season in 2023, posting a 3.38 ERA and 64:23 K:BB over 50.2 regular-season frames between the White Sox and Yankees. Middleton will give the Dodgers some experienced relief depth at Triple-A Oklahoma City.
