The Red Sox made a series of roster moves Thursday morning, most notably reinstating right-handed reliever from the 60-day IL. That move brings Bostons 40-man roster to capacity. Theyd previously had a vacancy after outrighting infielder . The Red Sox also activated outfielder from the 10-day injured list. To open active roster spots for Slaten and Refsnyder, they optioned southpaw to Triple-A Worcester and placed first baseman on the paternity list (where he can spend up to three days). Slaten, 27, is in his second season with the Red Sox after coming to Boston via the Rule 5 Draft in 2023. He was outstanding as a rookie in 2024, to sing 55 1/3 innings with a 2.93 ERA, a 25.9% strikeout rate, a tiny 4% walk rate and a strong 50% ground-ball rate. Hes had good results in 2025 as well, logging a 3.47 ERA in 23 1/3 frames, albeit with le ser rate stats. Hes been on the injured list since late May due to shoulder inflammation. Slatens strikeout rate Tyler Thurmond Jersey dipped to 17.8%, perhaps in part due to a significant drop in his slider usage. He threw nearly 25% sliders in 24 but is down to 8% in 25, instead favoring his curveball far more heavily (8.4% in 24, 21.6% in 25). Slatens walk rate has nearly doubled, up to 7.8%, but thats still comfortably better than average. Sustaining a 4% walk rate was always going to be tough it would be for any pitcher particularly considering Slatens 8.5% walk rate in his final minor league season. Even with some modest steps back this year, Slaten is a big arm wholl provide a notable boost to s bullpen. Hes been effective since day one in the majors, quickly pitching his way into a high-leverage role last year, and actually saw a bump in velocity prior to his IL placement, with his average four-seamer rising from 96.4 mph last year to 97 mph in 2025. Hell join , and as one of the primary setup options to closer , who is enjoying perhaps the most dominant season of his 16-year major league career. Quinton Martin Jr. Jersey
