Gillies will be sidelined for at least six weeks with a quad injury, Roch Kubatko of MASNSports.com reports.

Gillies had been in camp as a non-roster invitee and will now get a late start to the minor-league season. The 6-foot-8 right-hander posted a 2.68 ERA and 51:13 K:BB over 53.2 frames between Double-A Chesapeake and Triple-A Norfolk in 2025.

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.

Cole (elbow) will throw a live batting practice session Friday, Brendan Kuty of The Athletic reports.

It will be Cole's first time facing hitters since last March's Tommy John surgery with an internal brace. The veteran hurler's rehab has gone swimmingly to this point, and he will continue to check off boxes as he eyes a season debut in late May or early June.

Red Sox manager Alex Cora said Thursday that coaches are working with Oviedo to be more explosive with his delivery, Christopher Smith of MassLive.com reports. "Just a big dude that we gotta get moving," Cora said of the 6-foot-6, 275-pound right-hander. "Not work faster as far as like tempo, but move faster. And I think we accomplished that today."

Oviedo threw a two-inning live batting practice Thursday, and the manager said he's getting closer to what coaches are looking for. Cora also raved about the right-hander's extension, but strike-throwing remains key for the hurler, whose first spring start is scheduled for Wednesday against the Twins. Oviedo appears to be the frontrunner for a spot at the back end of the rotation. One candidate, Kutter Crawford (wrist), could open the season on the injured list, and two others, Connelly Early and Payton Tolle, may begin the year at Triple-A Worcester. Left-hander Patrick Sandoval is also in the mix, but he missed all of 2025 with an elbow injury.

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.

Manager John Schneider said Thursday that Bieber (forearm) has progressed to throwing from 120 feet, Keegan Matheson of MLB.com reports.

The team has already confirmed that Bieber will begin the regular season on the injured list due to forearm fatigue -- something he pitched through during Toronto's playoff run in 2025. Schneider added that he expects Bieber to begin throwing bullpen sessions within the next two weeks, at which point more information may emerge regarding how much time the right-hander will miss to begin the new campaign.

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.

Crawford (wrist/illness) could begin the season on the injured list, Chris Cotillo of MassLive.com reports.

Crawford is behind other pitchers in Red Sox camp following last year's right wrist surgery and a recent bout with the flu. He's throwing off the mound, but with several other candidates to fill the last spot in their rotation, the Red Sox could choose to slow-play Crawford after he missed the entire 2025 campaign. Crawford made 33 starts for Boston in 2024, posting a 4.36 ERA and 175:51 K:BB over 183.2 innings.
