The Red Sox announced Friday that they’ve signed veteran lefty Sean Newcomb to a minor league deal and invited him to major league spring training. Newcomb is represented by Klutch Sports. Boston also confirmed previously reported minor league deals/non-roster invites for right-handers Austin Adams, Robert Stock and Noah Davis. (We’ve previously written on their deals for Adams, Davis and Stock.)
Newcomb, 31, is a former first-round pick (Angels, 2014) and top prospect. The Halos shipped him to the Braves as part of their trade to acquire Andrelton Simmons ahead of the 2016 season, and for a couple years, Newcomb looked as though he could be a fixture on Atlanta’s staff in spite of sub-par command. He started 49 games for the Braves in 2017-18, registering a solid 4.06 ERA with a 23.3% strikeout rate but an ugly 12% walk rate. Atlanta bumped him to the ’pen in 2019, and the results were even more intriguing: 68 1/3 innings, 3.16 ERA, 22.2% strikeout rate, 9.9% walk rate.
Over the next three seasons, Newcomb’s results tanked. He pitched just 73 2/3 innings in the majors and logged a brutal 7.45 ERA. His strikeout rate held at 22.9%, but Newcomb’s walk rate jumped to 14.7%. After plunking only 10 hitters and tossing 11 wild pitches in 332 1/3 frames from 2017-19, Newcomb hit five batters and tossed eight wild pitches over those 73 2/3 frames from 2020-22. He not only saw his ability to throw strikes diminish — he saw his precision within the zone erode as well; after yielding an average of 0.97 homers per nine innings in ’17-’19, Newcomb averaged 1.59 long balls per nine frames in 2020-22.
Newcomb has spent the past two seasons with the A’s, pitching well in 2023 before undergoing season-ending knee surgery and struggling in 2024 on the heels of that procedure. He’s pitched 25 MLB innings over the past two seasons and allowed a dozen runs (4.32 ERA) on 17 hits, 17 walks, three hit batters and 24 strikeouts. He’s been far better in the minors, notching a 3.12 ERA in Triple-A between the Giants and A’s in 2023-24. He’s punched out 30.1% of opponents but again shown poor command (14.2%) in those two Triple-A seasons (totaling 40 1/3 innings).
Boston already has Aroldis Chapman, Brennan Bernardino and Justin Wilson as left-handed options locked into manager Alex Cora’s bullpen. Southpaw Zach Penrod is also on the 40-man roster. He worked more as a starter in the minors last year, but his path to the majors in 2025 would likely be in the bullpen, with Lucas Giolito returning and new acquisitions Garrett Crochet and Walker Buehler in the rotation.
