The Guardians selected Peterson's contract from Triple-A Columbus on Tuesday, Zack Meisel of The Athletic reports.

Peterson struggled a bit after being promoted to Triple-A in June, posting a 4.27 ERA and 1.37 WHIP across 90.2 innings compared to the 1.47 ERA and 0.82 WHIP he held in 55 frames at Double-A Akron. The 26-year-old's addition to the 40-man roster will prevent him from being selected in the Rule 5 Draft, but the Guardians will likely keep him in Triple-A to begin the 2026 campaign.

The Royals selected Zobac's contract from Double-A Northwest Arkansas on Tuesday, Anne Rogers of MLB.com reports.

The right-hander missed time in 2025 due to a knee injury, which limited him to 14 appearances. Zobac spent most of the campaign with Northwest Arkansas and had a 7.68 ERA over 36.1 innings, but the Royals still elected to shield him from potentially being selected in the upcoming Rule 5 Draft.

The Royals selected Kudrna's contract from Triple-A Omaha on Tuesday, Anne Rogers of MLB.com reports.

The 22-year-old righty spent most of last season at Double-A Northwest Arkansas, where he had a 4.21 ERA over 94 innings. Kudrna made four appearances for Omaha late in the season and struggled at the highest level of the minors with a 14.29 ERA.

The White Sox selected McDougal's contract from Double-A Birmingham on Tuesday.

McDougal turned in a 3.26 ERA and 1.33 WHIP to go with a 136:49 K:BB over 113.1 innings between High-A and Double-A in 2025. Considered one of the top pitching prospects in the White Sox's farm system, the 22-year-old will officially receive a spot on the 40-man roster to prevent another team from selecting him in the Rule 5 Draft, and he has a strong chance to make his MLB debut in 2026 and join a talent-deficient White Sox rotation.

The Red Sox selected Drohan's contract from Triple-A Worcester on Tuesday, Chris Cotillo of MassLive.com reports.

Drohan missed nearly four months of the Triple-A season with a forearm injury but was extremely effective when healthy, turning in a 2.27 ERA and 1.02 WHIP alongside a 67:16 K:BB through 47.2 innings. The 26-year-old southpaw will be ineligible for the Rule 5 Draft in December now that he owns a spot on Boston's 40-man roster, and he could compete for a spot on the Opening Day roster if his strong performance continues into spring training.

The Red Sox selected Sandlin's contract from Triple-A Worcester on Tuesday, Chris Cotillo of MassLive.com reports.

Sandlin began 2025 at Double-A Portland and posted a 3.61 ERA and 1.18 WHIP across 82.1 innings before receiving a promotion to Worcester. The 24-year-old righty struggled upon arriving at Triple-A (7.61 ERA, 2.07 WHIP), but the Red Sox will give him a 40-man spot to ensure he remains with the organization past December's Rule 5 Draft. He is likely to report to Worcester to begin the 2026 season.

The Angels selected Urena's contract from Triple-A Salt Lake on Tuesday.

The right-hander spent most of the 2025 campaign at Double-A Rocket City, where he had a 4.33 ERA, 1.35 WHIP and 121:74 K:BB across 139.1 innings. Urena moved up to Triple-A for his final outing of the season and could be back at the highest level of the minors to begin 2026.

The Astros selected Ullola's contract from Triple-A Sugar Land on Tuesday.

The move adds Ullola to the 40-man roster and protects him from next month's Rule 5 Draft. Ullola spent the entirety of the 2025 campaign at Sugar Land, finishing with a 3.88 ERA and 131:78 K:BB over 113.2 innings. The 23-year-old will compete for an Opening Day roster spot, but a career 15.6 percent walk rate in the minors suggests more seasoning is needed.

The Twins selected Rojas' contract from Triple-A St. Paul on Tuesday, Francys Romero of BeisbolFR.com reports.

Acquired from the Blue Jays in the Louis Varland trade, Rojas struggled in eight starts for St. Paul down the stretch, holding a 6.59 ERA and 28:23 K:BB over 27.1 innings. However, the 22-year-old southpaw has swing-and-miss stuff, having fanned 90 in 69 frames between his various minor-league stops in 2025. Rojas is now on the 40-man roster and protected from the Rule 5 Draft.

Arrighetti (elbow) is expected to be 100 percent for the beginning of spring training, Matt Kawahara of the Houston Chronicle reports.

Arrighetti missed the final month of the season with a right elbow injury, but he's considered healthy now and is "having a very productive offseason," per Astros general manager Dana Brown. The 25-year-old was limited to only seven starts at the major-league level in 2025, as he was sidelined four months with a right thumb fracture in addition to the elbow issue. Brown indicated that Arrighetti has a rotation spot for 2026 locked up.
