The Red Sox designated Mata (elbow/lat) for assignment Tuesday, Jen McCaffrey of The Athletic reports.

Mata missed the start of the season with a hamstring injury and missed the final three months due to shoulder and elbow soreness and never got surgery, which likely contributed to him getting squeezed off the 40-man roster. He is 25 and hasn't thrown more than 30 innings in a season since he threw 83 innings in 2022. Mata has a career 4.87 ERA, 1.75 WHIP and 70 strikeouts in 61 innings at Triple-A, and his best path forward is likely as a reliever who can just let it rip with his fastball and slider in short bursts.

The Red Sox designated Campbell (elbow) for assignment Tuesday, Jen McCaffrey of The Athletic reports.

Campbell missed the second half of 2024 with elbow inflammation and never got surgery, so the injury may have played a role in him losing his spot on the 40-man roster as Boston looked to protect some prospects from the Rule 5 draft. Campbell had a 2.20 ERA, 1.16 WHIP and a 19:5 K:BB in 14 appearances at Triple-A, but he gave up 12 earned runs in 6.2 MLB innings and his fastball velocity was down to 93.8 mph from the 95.0 mph he averaged in 2023 with Seattle.

The Guardians designated Gillispie for assignment Tuesday.

Gillispie yielded just two earned runs over eight MLB innings in 2024, but he also logged a 4.05 ERA and 1.24 WHIP over 113.1 Triple-A frames. His 40-man spot will be handed to Nic Enright, who consequentially is protected from the upcoming Rule 5 Draft.

The Guardians designated Strzelecki for assignment Tuesday.

Strzelecki was effective during his time in the majors last season, allowing just three runs over 11.2 innings with the Guardians. However, his 5.01 ERA at Triple-A Columbus makes him significantly less reliable than his MLB stat line would suggest, so the team will strip him of his 40-man spot and use it to protect fellow right-hander Franco Aleman from the upcoming Rule 5 Draft.

The Tigers designated White for assignment Tuesday.

White missed most of the 2024 season due to injury, and he most recently underwent an elbow procedure in August. White started throwing sessions at the end of September, but his spot on the 40-man roster was needed for several players that were added Tuesday in order to protect them from the upcoming Rule 5 Draft.

The Tigers designated Vanasco for assignment Tuesday.

Vanasco was optioned to Triple-A Toledo in September after making two scoreless appearances for the Tigers out of the bullpen. He made 11 total appearances in Toledo in 2024, allowing just two earned runs across 17 innings. The 26-year-old is being designated for assignment in order to create room for one of the three pitchers being added to the 40-man Tuesday.

The Tigers selected Lee from Triple-A Toledo on Tuesday.

Lee started the 2024 season in Triple-A Round Rock in the Rangers organization before being traded to the Tigers at the end of July. With Triple-A Toledo, the righty posted a 3.27 ERA and 1.23 WHIP across 22 innings in 17 appearances. The 26-year-old is now protected from the Rule 5 Draft in December.

The Rangers returned Coleman (elbow) to the Yankees on Tuesday, Kennedi Landry of MLB.com reports.

The Rangers selected Coleman in the 2023 Rule 5 Draft, but he never pitched for Texas while recovering from a procedure he underwent on his right elbow in April 2023. Because he never played, he'll now return to his previous organization and will remain without a spot on New York's 40-man roster.

The Rays designated Lovelady for assignment Tuesday, Marc Topkin of the Tampa Bay Times reports.

Lovelady is a roster casualty as the Rays look to clear space on Rule 5 Draft protection day. The lefty reliever holds a career 4.98 ERA and 90:36 K:BB over 99.1 innings covering parts of five big-league seasons.

The Rays and Sulser avoided arbitration by agreeing to a one-year contract Monday, Tricia Whitaker of Bally Sports Sun reports.

Sulser had been eligible for arbitration for a second time. The 34-year-old reliever holds a career 3.74 ERA and 158:71 K:BB over 149 innings covering parts of six big-league seasons.
