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.

Wow
Stop ruining baseball Red Sox! Geez a weez.
Between him and Oviedo, the Sox are forming quite a frontcourt.
I was thinking how the Sox will control the offensive glass. I thought though Breslow was trying to win on the defensive front…
Henry couldn’t land his NBA franchise so maybe he’s just choosing to turn one of the minors affiliates into one instead
Championship!
Probably signed him because of his extension. It certainly wasn’t because of anything he’s accomplished on either continent.
Dude is huge. Throws 99 with 7’0 extension. They have a “type”.
Sean – boy do they ever have a type. Driveline tells Breslow you need extension and rise, so he runs out and gets every pitcher that fits the mold.
Still need an infielder though….
Turn Turn love red and just y vibe
He has 59-0′ extension, and still can’t throw strikes!!
I remember when AA RP depth pickups use to get 500 responses.
Yes,….and 250/500 were stupid responses that had nothing to do with the player or were arguements about trivial junk or personal attacks. I do not mind fewer comments that are more on topic.
Yeah, those days were horrible.
Joe- gotta agree that less is more. Stopped reading comments on RS posts for a while it had gotten so bad
I made the duck boat comment on Facebook instead
Useful mop up guy, saving innings for the rest of the bullpen. And good for bench clearing brawls. Why not?
Contrary to popular belief you don’t actually need a pitcher who can hit the bull. Enough w/ the BS please & focus
swing and miss potential. taking a flyer, nothing more. Breslow loves guys that keep the ball out of play. If they can tweek this guy and Ovieto as well, this will have been worthwhile
That fits a sizable.chunk of the offensive strategy as well:
HRs, Ks, BBs, prioritized over contact and top percentile of .ba
Can he shoot the three?
Depth for the minors is all. High octane, wild as hell depth for the AAA squad. There should be no expectations he pitches an inning in MLB. If he does, the season went sideways and was over before he got called up.
It’s a long season. Guys will struggle/get hurt. Need arms to fill the minors and maybe throw a mop up inning here or there in the bigs. Does not mean the season has gone sideways it’s just a slog.
He plays third base in the South Boston Slow-Pitch Softball League. So we’re all set now.
