The Red Sox signed Wilson to a one-year, $2.25 million contract Thursday, Rob Bradford of WEEI.com reports.
He will have the ability to earn an additional $750,000 in incentives. After missing the 2023 season following Tommy John surgery, Wilson held a 5.59 ERA but a 51:13 K:BB across 46.2 frames for the Reds in 2024. The 37-year-old will give the Red Sox another lefty in the bullpen alongside Brennan Bernardino.
