Red Sox Reassign Veteran in Recent Wave of Spring Training Cuts The Boston Red Sox are beginning to trim their Spring Training roster, including Austin Adams, Isaiah Campbell, and Noah Davis.

MARCH 17, 2025 • NEWSOBSERVER.COM

Sent out to minor-league camp The Red Sox reassigned Campbell to minor-league camp Monday.

Impact Along with right-handers Austin Adams and Noah Davis, Campbell was one of three relievers competing for a spot in the Opening Day bullpen who was cut from big-league camp Monday. Campbell missed most of the 2024 season due to arm injuries but made eight appearances out of the Boston bullpen, logging a 16.20 ERA and 2.40 WHIP over 6.2 innings.

MARCH 17, 2025 • ROTOWIRE

Slated to pitch Thursday Campbell (elbow) is listed as one of Boston's scheduled pitchers for Thursday's Grapefruit League game against Detroit, Evan Woodbery of MLive.com reports.

Impact Campbell finished the 2024 season on Boston's injured list due to right elbow inflammation and was then outrighted off the 40-man roster in November. After a brief free-agency period, Campbell re-signed with Boston on a minor-league deal and received an invitation to big-league spring training. He'll make his first Grapefruit League appearance Thursday, which indicates that his prior elbow injury is no longer a concern.

FEBRUARY 27, 2025 • ROTOWIRE

Quick return to Boston Campbell agreed to a minor-league deal with the Red Sox on Friday, Chris Cotillo of MassLive.com reports.

Impact Campbell was non-tendered by the Red Sox on Friday, but just hours later this new deal was announced. He's likely to begin the season working in relief with Triple-A Worcester.

NOVEMBER 23, 2024 • ROTOWIRE

Entering free agency Boston non-tendered Campbell (elbow) on Friday, Mac Cerullo of the Boston Herald reports.

Impact Campbell was sidelined for the second half of the 2024 season due to right elbow inflammation, which played a part in the Red Sox designating the 27-year-old right-hander for assignment Tuesday. He'll now enter free agency, and while he could opt to remain in Boston on a minor-league deal to continue his rehab, Campbell will have the freedom to explore other opportunities. Across 14 outings with Triple-A Worcester in 2024, Campbell posted a 2.20 ERA and 1.18 WHIP over 16.1 innings.

NOVEMBER 23, 2024 • ROTOWIRE

Loses 40-man roster spot The Red Sox designated Campbell (elbow) for assignment Tuesday, Jen McCaffrey of The Athletic reports.

Impact 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.

NOVEMBER 20, 2024 • ROTOWIRE

Moved to 60-day IL The Red Sox recalled Campbell (elbow) from Triple-A Worcester on Saturday and placed him on the 60-day injured list, Gabrielle Starr of the Boston Herald reports.

Impact The move opens up a spot on the 40-man roster for Trevor Story (shoulder), who's being activated from the 60-day IL on Saturday. Campbell hasn't pitched since July 13 and it's unclear if he'll be healthy before the regular season ends.

SEPTEMBER 7, 2024 • ROTOWIRE

On Triple-A IL with elbow injury Campbell was placed on the 7-day injured list at Triple-A Worcester on Tuesday with right elbow inflammation, Chris Cotillo of MassLive.com reports.

Impact It's not clear how long Campbell might be sidelined, but certainly he won't be an option for the Red Sox' bullpen anytime soon. The 26-year-old has been tagged for 13 runs (12 earned) over 6.2 innings with Boston this season but has pitched well at Worcester, holding a 2.20 ERA and 19:5 K:BB across 16.1 frames.

Starting rehab assignment Campbell (shoulder) will begin a rehab assignment with Triple-A Worcester on Wednesday, Chris Cotillo of The Springfield Republican reports.

Impact Campbell has been out since mid-April with a right shoulder impingement, but he's finally ready to move on the final phase of his recovery process. He will likely need multiple rehab appearances before returning from the 15-day injured list and rejoining Boston's bullpen.

He's allowed one hit one three hits and a walk while striking four over 4.1 innings.
