The Red Sox are going to select right-hander Tayron Guerrero to their roster, per reporting from Andrew Parker of SoxProspects.com. He’ll be back in the big leagues for the first time since 2019. Righty Zack Kelly has been optioned as a corresponding active roster move, per Chris Cotillo of MassLive. The Sox will need to make a corresponding move to open a 40-man roster spot. That will likely involve moving someone to the 60-day injured list, with Kutter Crawford being a logical candidate.
It’s an incredible comeback story for the 35-year-old. Guerrero was in the big leagues from 2016 to 2019, pitching for the Padres and Marlins. He logged 106 innings with a 5.77 earned run average. He lost his roster spot ahead of the 2020 season. Since then, he has alternated between minor league deals and time spent in Japan, without a ton of success. He was with the Chiba Lotte Marines in 2022 and 2025. The first stint overseas was okay, with Guerrero posting a 3.52 ERA, but he had a 6.41 ERA last year. In his minor league work from 2021 to 2024, he posted a 7.62 ERA.
He signed a minor league deal with the Sox this offseason and has been shoving in Triple-A. He has thrown 19 2/3 innings for the WooSox, allowing just two earned runs for a 0.92 ERA. His 8% walk rate is right around average, while his 29.3% strikeout rate is quite strong and his 69.6% ground ball rate is massive. His fastball is still averaging in the upper 90s, with his slider and changeup coming in around 90ish.
The Sox will take a chance on Guerrero to see if he can translate any of that to the big leagues. Given his age and his recent track record, it’s an unusual move, but there’s obvious appeal in his numbers so far this year. If the gambit doesn’t pan out, Guerrero is out of options.
