Tayron Guerrero: Everything you need to know

The Red Sox will call up Guerrero from Triple-A Worcester prior to Friday's contest versus the Twins, Francys Romero of BeisbolFR.com reports. It's a story of perseverance for the 35-year-old Guerrero, who has not pitched in the big leagues since 2019. He's earned the promotion by collecting a 0.92 ERA and 22:6 K:BB over 19.2 innings while notching three saves with Worcester. It's unclear what the corresponding move will be in order to free up a roster spot for Guerrero.

The Red Sox have signed Guerrero to a minor-league contract, Andrew Parker of SoxProspects.com reports. Guerrero played in Japan's Nippon Professional Baseball league with the Chiba Lotte Marines last year, posting a 6.41 ERA with a 15:8 K:BB over 19.2 innings spanning 21 games. The righty reliever has 113 regular-season games of MLB experience, logging a 5.77 ERA, 1.66 WHIP and 111:67 K:BB across 106 frames between the Padres and Marlins. Considering that Guerrero last pitched in the majors in 2019, he's a long shot to make an impact with the Red Sox during the upcoming campaign.

The Chiba Lotte Marines of Nippon Professional Baseball signed Guerrero to a one-year, $600,000 contract Tuesday, Francys Romero of BeisbolFR.com reports. Guerrero spent most of the 2024 season at Triple-A Salt Lake in the Angels organization, collecting a 5.73 ERA and 32:11 K:BB over 33 frames. The tall right-hander will turn 34 in January and last pitched in the majors in 2019.
