Zack Kelly has elected free agency.

The 31-year-old right-hander passed through waivers unclaimed after being designated for assignment by the Red Sox earlier in the week. Kelly did a nice job in 17 appearances for the Red Sox in 2026, registering a 3.31 ERA, 1.29 WHIP and a 14/7 K/BB ratio over 16 1/3 innings. It’s possible that he could wind up securing a big league deal this winter.
