Mahle has been battling through an illness but is expected to face hitters next week, Alex Pavlovic of NBC Sports Bay Area reports.

Mahle has fallen behind in spring training while under the weather, but the illness isn't considered a long-term concern that will keep the 31-year-old right-hander sidelined for long. Mahle signed a one-year deal with the Giants in late December after spending the last two seasons with the Rangers. He appeared in 16 games for Texas in 2025, finishing 6-4 with a 2.18 ERA, 1.13 WHIP and 66:29 K:BB across 86.2 innings.

Jones (elbow) will throw a live batting practice session Friday, Colin Beazley of the Pittsburgh Post-Gazette reports.

It'll be the first time Jones has faced hitters since he underwent a UCL reconstruction on his right elbow last May. The young right-hander has already been placed on the 60-day injured list, so he will not be eligible for his season debut until late May. A return by that time would be a best-case scenario, but Jones' rehab has gone well to this point.

Keller will make his Grapefruit League debut Sunday against the Rays, Jason Mackey of the Pittsburgh Post-Gazette reports.

Keller has turned into a consistent starter for the Pirates, though he endured a tough second half of 2025 by posting a 5.56 ERA and 1.50 WHIP across 57.1 innings. He's looking to be more consistent in 2026, but he's posted an ERA in the low 4.00s with a WHIP in the mid 1.20s in each of the last three seasons. Keller will remain a stalwart in the rotation in 2026 and could serve as the No. 2 starter behind Paul Skenes.

Dotel will start Saturday's Grapefruit League game against the Orioles, Jason Mackey of the Pittsburgh Post-Gazette reports.

Dotel was added to the 40-man roster this offseason and will start Pittsburgh's first spring training contest. He started 27 games with Double-A Altoona in 2025, posting a solid 131:43 K:BB across 125.2 frames. Dotel will likely begin the season at Triple-A Indianapolis, but he could be promoted to the majors during the summer months if injuries occur in the Pirates' rotation.

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.
