Cannon is competing for a rotation spot during spring training, Scott Merkin of MLB.com reports.

Cannon began the 2025 season in the White Sox's rotation but was demoted to the bullpen and also had a stint in the minors in the second half of the campaign. Merkin suggests the White Sox have as many as 10 pitchers competing for rotation spots, and Cannon's chances of securing a role to begin the season may not be very strong after Chicago added Anthony Kay, Erick Fedde and Sean Newcomb this offseason. Nevertheless, he'll get his first chance to improve his chances in Friday's Cactus League debut against the Cubs.

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, but 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 start 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 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.

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.

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.

Montero has yet to report to the Yankees' camp due to visa problems, Bryan Hoch of MLB.com reports.

Montero inked a minor-league contract with an invitation to spring training last week, but he's yet to report. It shouldn't greatly affect his preparation as long as his absence doesn't stretch on too long, but it will not help Montero's longshot bid to win a bullpen job.

McArthur (elbow) is considered healthy but will be eased into a throwing program this spring, Jaylon T. Thompson of The Kansas City Star reports.

McArthur had surgery last offseason to insert two screws into his right elbow to help stabilize a stress fracture. He then had another procedure in July to remove the screws after they had caused an allergic reaction in his elbow. McArthur wound up not pitching at all in 2025, but he's been throwing off the mound for a few months. He was also diagnosed with a Grade 1 UCL sprain prior to the first elbow surgery, so it's no surprise the righty is being slow-played this spring after all the missed time. McArthur should have enough time to be ready for Opening Day if he can avoid setbacks.
