Red Sox Sign Tayron Guerrero To Minor League Deal

The Red Sox announced the signing of reliever Tayron Guerrero to a minor league deal with an invite to MLB camp. Andrew Parker of Sox Prospects first reported the agreement earlier this month.

Guerrero returns to affiliated ball after spending the 2025 season in Japan. The hulking 6’8″ righty signed with the Chiba Lotte Marines last offseason. It was his second stint with the club, as Guerrero also pitched for the Marines back in 2022. His first stint went better than last year’s, as he allowed a 6.41 ERA over 19 2/3 NPB innings. He spent the majority of the season with their minor league affiliate as a result.

The 35-year-old Guerrero last pitched in the majors in 2019. He has 106 innings of MLB experience, turning in a 5.77 earned run average. Guerrero has allowed an even seven earned runs per nine over 117 career Triple-A frames. Various teams have been intrigued enough to continue giving him looks as a depth reliever on the strength of his velocity. Guerrero averages 99 MPH on his fastball but has never had great feel for command.

Boston will give the Colombian-born hurler a look in camp. He’s unlikely to win an Opening Day job but will have an opportunity to put himself on the radar for a midseason call if he impresses during exhibition play and with Triple-A Worcester.
