Dollander believes he fixed a mechanical flaw with his delivery this offseason, Thomas Harding of MLB.com reports.

Dollander said he got "too coil-y in my legs, in my leg kick," which led to him throwing across his body and affected his command. After working with with T.J. Galenti, a Florida-based data scientist and baseball performance coach, Dollander said his mechanical problem was fixed "pretty fast." Dollander added that he's now able to better find the strike zone with his fastball and slider, and he's also "getting the 'vert' (induced vertical break) back" on his heater. The 24-year-old entered Rockies camp healthy following a late-season knee injury last year, and he's cemented into the Opening Day rotation. Dollander posted a 6.52 ERA, 1.55 WHIP and 82:49 K:BB through 98 innings across 21 starts in his rookie season, with most of the damage done at home (9.98 ERA).

Mets manager Carlos Mendoza said Thursday that Senga hit 97 mph in a live batting practice session Thursday, Anthony DiComo of MLB.com reports.

Senga averaged 95.7 mph with his four-seamer in his rookie season and 94.7 mph with the pitch in 2025, so topping out at 97 mph already in camp seems like a good sign. The 33-year-old posted a 3.02 ERA in 22 outings for the Mets last season, but his strikeout rate dipped to 22.6 percent and he finished the year in the minors after a rough stretch. If healthy, Senga should open 2026 in the Mets' rotation.

Snelling will start for the Marlins in their Grapefruit League opener Saturday against the Mets, Christina De Nicola of MLB.com reports.

The southpaw is set to work only one inning, but Snelling is in camp looking to make as many good impressions as possible. Miami doesn't have a spot for him in the Opening Day rotation after signing Chris Paddack, but after being named the organization's Minor League Pitcher of the Year in 2025, Snelling could be the next man up in case of an injury. The 22-year-old delivered a dazzling 1.27 ERA, 0.98 WHIP and 81:17 K:BB over 11 starts and 63.2 innings for Triple-A Jacksonville last season after a mid-July promotion from Double-A.

Canning (Achilles) will begin the season on the injured list but "might not be there for very long," AJ Cassavell of MLB.com reports.

Recovering from a torn left Achilles, Canning said Tuesday that he feels 100 percent when throwing off the mound, but he still has some work to do in regard to the running and agility portion of his rehab. Cassavell suggests that Canning could be ready for his season debut around late April or early May, though a there's no clear timetable just yet. The right-hander held a 3.77 ERA and 70:35 K:BB across 76.1 innings for the Mets in 2025 before getting hurt. Once healthy, Canning should slot into the Padres' rotation.

Musgrove (elbow) is considered a full participant in Padres camp but will have his workload watched early in the season after missing the entirety of the 2025 campaign, Kevin Acee of the San Diego Union-Tribune reports.

Musgrove is coming back from Tommy John surgery but will not have a strict innings limit in 2026 in his age-33 season. The Padres will be sensible about how hard they push him early on, however, and an initial six-man rotation is one avenue they're considering. Musgrove boasts a 3.20 ERA, 1.11 WHIP, 25.5 percent strikeout rate and 6.1 percent walk rate in his four seasons with the Padres.

Waldrep will undergo surgery Monday to remove loose bodies from his right elbow, Mark Bowman of MLB.com reports.

Bowman reported previously that if surgery was recommended for Waldrep, the pitcher would likely be sidelined for approximately three months. The right-hander will be placed on the 60-day injured list, though that transaction hasn't officially been made yet. Waldrep showed signs of a breakout in 2025 with a 2.88 ERA, 1.19 WHIP and 55:22 K:BB over 56.1 innings, but it will be a while before he's seen in a big-league uniform again. With Spencer Schwellenbach also undergoing an elbow procedure, Joey Wentz and Bryce Elder have moved up in Atlanta's rotation pecking order.

Dobbins (knee) will travel Wednesday to visit a doctor in Wisconsin, where he hopes to be fully cleared for spring-training activities, Derrick Goold of the St. Louis Post-Dispatch reports.

Recovering from last July's right ACL surgery, Dobbins has thrown bullpen sessions and live batting practice sessions with the rest of the Cardinals' pitchers, but his fielding and running has been limited. As long as he gains clearance Wednesday, Dobbins should make some Grapefruit League appearances for St. Louis. However, the late start likely takes him out of the Opening Day rotation competition.

Phillips is part of a group competing for the final spots in the Reds' bullpen, Mark Sheldon of MLB.com reports.

Phillips made the transition from starter to reliever in 2025 following a diagnosis of thoracic outlet syndrome (TOS). To treat and manage TOS, the right-hander received Botox injections, which alleviated the symptoms and allowed him to pitch in shorter stints. Phillips was dominant over the final six weeks of 2025, using a two-pitch mix of four-seamers and sweepers (0.53 ERA, plus-5 Run Value) to post a 1.80 ERA with 28 strikeouts and eight walks over his final 17 appearances. The right-hander will compete with the likes of Sam Moll, Zach Maxwell and Luis Mey for a spot on the Opening Day roster.

Stone (shoulder) threw a bullpen session at spring training Tuesday, Sonja Chen of MLB.com reports.

Stone missed the entirety of the 2025 season while recovering from right shoulder surgery, but he's healthy entering camp, and Dodgers GM Brandon Gomes said over the winter that he expected Stone to be ready for spring training. Stone's presence on the mound confirms that, and the right-hander should have a normal buildup this spring. Stone is tentatively expected to begin the 2026 season in the minors.

Steele (elbow) has been throwing 30-pitch bullpen sessions and is targeting a return to the majors in May or June, Maddie Lee of the Chicago Sun Times reports.

Steele underwent UCL revision surgery on his left elbow in mid-April of last year, and the southpaw is currently building up strength before he's able to return later in 2026. He was Chicago's Opening Day starter two years ago and has a career 3.30 regular-season ERA, so there's plenty of upside in his arm. However, the Cubs will undoubtedly be cautious with his return, and there could be a good degree of rust as well. Fantasy managers should target the 30-year-old as an intriguing stash candidate in 2026, though expectations should be tempered due to the long layoff. It's also possible Steele returns to a bullpen role, at least initially, with Chicago adding Edward Cabrera in the offseason to bolster its rotation.
