Free agent left-hander Sean Newcomb has gotten attention from teams both as a starter and reliever, write Will Sammon, Katie Woo and Ken Rosenthal of The Athletic. The 32-year-old began the season in the Red Sox’s rotation but moved to relief after five starts.
Newcomb is coming off his best season in at least six years. A former first-round pick who held a rotation spot with the Braves between 2017-18, Newcomb moved primarily to the bullpen in 2019. He pitched well that year but struggled with both injuries and a lack of command over the next few seasons. He combined for 98 2/3 MLB innings between 2020-24 and took a minor league contract with Boston last winter.
The Massachusetts native surprisingly nabbed the fifth starter spot out of camp. He only once completed five innings and allowed four-plus runs in three out of five outings. The Sox moved him to a long relief role when Lucas Giolito returned from a hamstring injury in late April. Newcomb was solid out of the bullpen but was nevertheless pushed off the roster. The Sox traded him to the Athletics, for whom he’d logged some time as a depth reliever in 2023-24.
Newcomb turned into an unexpectedly important bullpen piece for Mark Kotsay. He fired 51 1/3 frames of 1.75 ERA ball while working 1-2 innings at a time. Newcomb punched out a quarter of opponents against a career-best 7% walk rate. He worked in the 93-94 MPH range with both his four-seam fastball and sinker while using a low-80s curveball as his best secondary pitch. Newcomb dabbled with a cutter and changeup against right-handed batters, but the fastball/curve combination was where he found most of his success.
The 6’5″ southpaw pitched particularly well down the stretch, turning in a 0.96 ERA over 28 innings after the All-Star Break. His season ended a couple weeks early because of elbow inflammation, but there’s no indication that’ll be an issue going into next season. Durability has generally been a concern, albeit mostly with lower half injuries. Newcomb missed time with a sprained ankle in 2022 and battled knee problems over the following two seasons.
Newcomb’s strong year was enough to land a big league contract this time around. A one-year deal seems likely, though it’s not out of the question he commands a modest two-year guarantee. Sixth starters and swing types like Griffin Canning, Joe Ross, Jakob Junis, Colin Rea and Michael Lorenzen landed contracts between $4-7MM last winter. Newcomb’s former teammate Michael Soroka pulled a $9MM deal from the Nationals at the higher end of that range, though he’s five years younger and had shown more strikeout potential in the bullpen.
