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.

Rumfield will have a chance to win a roster spot at first base this spring, Patrick Saunders of the Denver Post reports.

The Rockies acquired Rumfield in an unheralded trade in late January, but he'll have the chance to immediately contribute for his new club. Colorado has competition across most of its infield this spring, and manager Warren Schaeffer said that the starting role at first base is "wide open." Rumfield was previously blocked in the Yankees organization, but he posted a 121 wRC+ across 587 plate appearances at Triple-A Scranton/Wilkes-Barre in 2025. He also won a Gold Glove with Double-A Somerset in 2023, so his glove could also help his case for a roster spot.

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.

Triolo is expected to start at third base for the Pirates to begin the 2026 season, Kevin Gorman of the Pittsburgh Tribune-Review reports.

Triolo is an elite defender at both second and third base, and he is also capable of filling in at shortstop. The Pirates value that versatility, but the team has failed to land any of their targets at third base this offseason. That leaves Triolo as the favorite to start at the hot corner, though his productivity as a hitter could dictate his ability to remain an everyday player. Triolo has a career 87 wRC+ across 1,031 plate appearances, though he posted a 117 wRC+ across 216 plate appearances in the second half of 2025.

Cubs manager Craig Counsell said Thursday that Imanaga has been throwing harder early this spring, Bruce Levine of 670TheScore.com reports.

Counsell didn't offer specifics on Imanaga's velocity, but he believes the left-hander wasn't throwing as hard last season because a hamstring injury caused his mechanics to get out of whack. After averaging 91.7 mph and earning a plus-4 run value by Baseball Savant with his four-seamer in 2024, Imanaga averaged 90.8 mph and netted a minus-10 run value in 2025. The southpaw accepted a one-year, $22.025 million qualifying offer this offseason to return to the Cubs for 2026.

Whisenhunt was sitting 96-97 mph during a simulated game Thursday, Justice delos Santos of The San Jose Mercury News reports.

Delos Santos notes that the readings were courtesy of Trackman, so it's a legitimate velocity increase for Whisenhunt, who averaged 92.6 mph with his four-seamer last season. It will be interesting to watch whether the southpaw is able to carry the velocity spike into Cactus League play and the regular season, as it could help spur a breakout. Whisenhunt entered spring training likely on the outside looking in for a spot in the Giants' rotation after holding a 5.01 ERA and 16:12 K:BB over 23.1 innings covering five starts in 2025.

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.

Aguiar (elbow) is without restrictions in Reds camp and competing for the final spot in the rotation, Mark Sheldon of MLB.com reports.

Aguiar missed the entire 2025 season after having Tommy John surgery in October 2024, but he's now 16 months removed from the operation and participating fully in camp. The 24-year-old is in the rotation mix for Cincinnati but is almost surely ticketed for Triple-A Louisville following a lost season. Aguiar made seven starts for the Reds in 2024, holding a 6.25 ERA and 19:12 K:BB over 31.2 innings.
