Tanner McDougal RP | CHW
White Sox's Tanner McDougal: Shielded from Rule 5 Draft
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.

Red Sox's Shane Drohan: Grabs spot on 40-man roster
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.

David Sandlin SP | CHW
Red Sox's David Sandlin: Added to 40-man roster
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.

Chris Murphy RP | CHW
White Sox's Chris Murphy: Dealt to White Sox
The Red Sox traded Murphy to the White Sox on Tuesday in exchange for Ronny Hernandez, Bob Nightengale of USA Today reports.
Murphy was effective as a big-league reliever in 2025, finishing the regular season with a 3.12 ERA and 1.18 WHIP across 34.2 innings. The White Sox aren't working with much depth in their bullpen, so the 27-year-old left-hander could see regular work in high-leverage opportunities with his new organization.

Walbert Urena SP | LAA
Angels' Walbert Urena: Added to 40-man roster
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.

Jack Brannigan 3B | PIT
Pirates' Jack Brannigan: Protected from Rule 5 Draft
The Pirates selected Brannigan's (shoulder) contract from Double-A Altoona on Tuesday, Alex Stumpf of MLB.com reports.
Brannigan slashed .225/.329/.358 across 237 plate appearances at Double-A Altoona in 2025 before suffering a shoulder injury in June that required season-ending surgery. The 24-year-old infielder will join Pittsburgh's 40-man roster to ensure he remains with the organization past the Rule 5 Draft in December, though he shouldn't be expected to appear in the big leagues in 2026.

Esmerlyn Valdez RF | PIT
Pirates' Esmerlyn Valdez: Added to 40-man
The Pirates selected Valdez's contract from Double-A Altoona on Tuesday, Francys Romero of BeisbolFR.com reports.
Valdez split his time between High-A and Double-A ball in 2025, slashing .284/.375/.521 with 27 homers, 87 RBI and 76 runs scored between the two levels. His impressive performance will grant him a place on Pittsburgh's 40-man roster heading into the 2026 campaign, but he's likely to begin the year at Double-A Altoona or Triple-A Indianapolis.

Miguel Ullola RP | HOU
Astros' Miguel Ullola: Joins 40-man roster
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.
-
Ramon Urias 3B | STL
Astros' Ramon Urias: Booted off 40-man roster
The Astros designated Urias for assignment Tuesday.
The transaction frees up a spot on the 40-man roster for the addition of Miguel Ullola. Urias is projected to make more than $4 million in his final year of arbitration eligibility, which the Astros felt was too much. The 31-year-old is a career .257/.321/.403 hitter and capable defender at second and third base, so he shouldn't have difficult landing a major-league contract this winter, assuming he clears waivers and becomes a free agent.

Michael King SP | SD
Michael King: Passes on qualifying offer
King rejected the Padres' $22.025 million qualifying offer Tuesday, Alden Gonzalez of ESPN.com reports.
King was limited to 15 regular-season starts in 2025 due to shoulder and knee issues, but it's still not a surprise he elected to turn down the qualifying offer. King posted a 3.44 ERA over 73.1 innings last year and had a 2.95 ERA during his first season as a full-time starter in 2024. Extending the qualifying offer will net the Padres a compensatory draft pick, assuming he doesn't re-sign with the team.
