Red Sox Outright Luis Guerrero

By Steve Adams | November 14, 2025 at 11:24am CDT

Red Sox right-hander Luis Guerrero, who was designated for assignment last week, went unclaimed on outright waivers and has been assigned to Triple-A Worcester, reports Chris Cotillo of MassLive.com. He lacks the service time or prior outright needed to elect free agency, so he’ll remain with the organization as non-roster depth.

Guerrero, 25, has pitched 27 1/3 innings of relief for Boston over the past two seasons. He sports a sharp 2.63 ERA in that time and sits 96.9 mph with his heater, perhaps making it a bit surprising that he went unclaimed at first glance. However, Guerrero went on the injured list with an elbow sprain back in June and never returned — though he never required any type of surgery to address the injury. The Sox moved him to the 60-day IL in August. Guerrero also has poor command, walking nearly 15% of his opponents against just a 17.6% strikeout rate in the majors.

The hard-throwing Guerrero’s minor league numbers are more alarming. He has a respectable enough 3.89 ERA in parts of three Triple-A seasons but saw that mark jump to 4.39 in 2025. He’s walked or plunked an untenable 17.4% of his opponents at the top minor league level, and in 2025 walked nearly 19% of the minor league hitters he faced in 31 innings.

Guerrero has, at times, posted gaudy strikeout and swinging-strike rates. The velocity is impressive, and he has a pair of minor league options remaining. That all makes him a nice depth piece whom the Sox are surely glad to retain, but he’ll need to further refine his well below-average command if he’s to carve out a steady role in a major league bullpen. Assuming his elbow is healed, he’ll be in big league camp with the Sox and hope to pitch his way back into the mix for a 40-man roster spot.

    This article would fit perfectly about Hicks, what a horrendous contract. Needless to say I’m skeptical about Breslow’s belief he can “fix” him.

      Fever, let’s be honest. The Hicks’ contract was the only way to unload 100% of Devers’ pact. Just accept the money as wasted and hope for a surprise.

        Dewey – If that’s true the Sox could have just agreed to pay $31M of Raffy’s salary. That way they don’t burn a roster spot on Hicks.

          They thought he was worth the investment Fever. Henry looks at it as an opportunity. Now though, Hicks should prove himself in Spring Training or get cut. My guess is he doesn’t but ends up on the 60 day injury list…

        Thank God they unloaded 100% of Devers pact. The lineup surely doesn’t miss his 140 OPS+ in 2025.

        Meanwhile the Sox are paying Hicks 12.5MM for 2026 and 2027. Can’t believe we got so lucky. Now they need to get a bat to replace Devers and they now need another 3B. What a fantastic move. And they’re out a second round draft pick. Nice work.

          Suit – your first post said you were glad that they were able to keep Guerrero, and this one says you are happy to get rid of Devers. Something seems wrong with those two posts…..
          How were they better exactly? Hitting less home runs? Making more errors? Having a lower fielding percentage than 2024? Remember how everyone said Devers defense cost wins?
          Great teams aren’t made by shedding great players and keeping around terrible middle relievers.
          Are the Red Sox better with:
          Devers or Jordan Hicks
          Betts or Connor Wong
          Sale or Grissom…..
          The goal is to stack great players ala Manny and Papi, Pedro and Schilling.
          The simple truth is Breslow got played by Scott Boras and now we’re filling the same holes we had before 2025 just now without Devers to kick around

          It was never about his bat declining and 100% about his immature attitude, unwillingness to become a team player and clubhouse culture. Everyone talks about how Bregman and Story improved the clubhouse. No disrespect meant but Devers’ me first and sulking attitude did not.

          Yes, I agree his attitude was poor and a detriment. But, for the six years prior he was a great teammate and clubhouse presence. So, maybe Breslow fixes it and we are all laughing about it now. Or, maybe you dont continually lie to your employees. How do you and your coworkers feel when your boss is a jerkoff?
          That said, how was Manny’s demeanor? Nomar’s? Since when do baseball players have to be rays of sunshine? They dont, go out and hit the ball……

          Well, what’s done is done and he’s gone now. So like Joemo said, now we need to replace Bregman and Devers, pay Jordan Hicks and give up a draft pick

          I need to empty the chamber on this Devers debate so I dont have to post about it anymore. I have the 100%, iron clad, apples to apples comparison.
          When the Yankees wanted to obtain Alex Rodriquez they asked an inferior defensive player, who played the same position, to change positions. The inferior defensive player made a big fuss about not moving off “his” position. What did the Yankees do? Did they only keep one player? No, they figured it out, and they won championships.
          Can we just stop saying the Sox are better off without Devers and all move on together, pretty please (?)

          Sad – the whole “Sox were better without Devers” statement so so dumb. I don’t get how people can say that with a straight face.

          With Devers, Sox were projected to win the American League Pennant. When they traded Devers in the middle of the season, way before the trade deadline, the team then limped into the playoff and lost in the wild card game.

          That’s not better without Devers. That’s much worse. People will then go “well they had a better record without Devers”. Yeah because the pitching went from horrible outside of Crochet to pretty good. They also finally called up Roman Anthony. Those things would have happened if Devers was still there.

          I love the Jeter analogy though, I’ll be stealing it if people keep making the dumb statements about Devers.

          Sad: The Red Sox turned the season around after trading Devers and made the playoffs. Their record with Devers in 2025 was 37-36. After they traded Devers on June 15th, their record was 52-37. I’m happy they kept Guerrero. I think he will likely help the Red Sox at some point. I’m also fine with trading Devers. They were better without him. I also don’t want Devers for 8 more years. I don’t think he will age well.

          I think the Red Sox tried to fix the Devers situation. John Henry even traveled to Kansas City to meet with Devers. Looks like they concluded it was not fixable and they traded him.

          And there’s many others.

          I didn’t agree with it, I think it was a overreaction to the Bregman signing and Cole injury. But it’s what the experts were predicting. Believe em or not, that’s what they said.

          Suit – its an argument no side wins. So, no use beating a dead horse. I think Crochet had more to do with that than Devers.

          Here’s a hypothetical:
          Say the Sox signed Alonso instead of Bregman last offseason. Are the results better or worse than than limping into the wildcard and losing to a mediocre Yankee team?
          In five years if you want to talk about Devers not being able to play you’ll probably be on solid ground, but in 2026, 2027 and probably 2028 he’s still a top hitter in the sport

          Sad: So, you think Devers will be good for 3 years and then bad for the last 5 years of his contract which is $31M per year? That sounds like a contract I would get rid of when I could.

          No, i’m saying he’s still at the peak of his career for three and will start to decline, from peak to 80%, 70%, etc, not fall off a cliff from one year to the next.
          You’re saying you’re happy giving up four years of the prime of his career because five years later hes 70% of what he was….that doesn’t make any sense

          Yes because I am not an expert in baseball. It is not my job to research baseball players and teams.

          I might not agree with something that say my doctor/lawyer/financial advisor/etc says, but they’re the expert. It’s their job to know the subject.

          Devers has had back issues, shoulder issues and attitude issues. I don’t think he is a good long-term bet at his high cost.

          Suit – is Aaron Judge going to be as good at 39 as he is at 33? Whoa, the Yankees should probably trade him right now, look out Dodgers, Ohtani might not be hitting 50 hrs in ten years…..the whole argument makes no sense.
          I’m not saying this to you, dont get my tone wrong, its not personal, i just dont understand why people say that

          It’s so simple, isn’t it? When they don’t win, it’s because of the dumb moves the FO made. When they make the playoffs, it’s in spite of the FO’s dumb moves. I get it now!

          Sad: The Red Sox were better after Devers left and made the playoffs. I don’t see any point in mourning the Devers trade unless you are looking for something to be negative about.
