Cubs just gifted Guardians chance to sign relief arm who would fill obvious need in bullpen

There are very few MLB careers like Colin Rea’s. He’s pitched for six different franchises, worked as both a reliever and bullpen option, been an impact postseason pitcher and even been a part of a rescinded trade. 

But he hit free agency earlier today after the Cubs declined his $7.5 million option for 2027 in lieu of a $1 million buyout, which could serve as the precursor for the next chapter of his career occurring in Cleveland. 

Think about: Rea has all the traits the Guardians love. He’s a relatively cheap, veteran swingman presence who has above average extension (71st percentile in extension). He wouldn’t be the flashiest signing in the offseason, but it’s almost like he was designed in a lab to stand you to the Guardians. 

Colin Rea would be a great fit in the Guardians' bullpen

Rea spent the past two seasons with the Cubs where he posted a 4.13 ERA in 296 1/3 innings. That’s about as league average as you can get. 

That tenure with the Cubs started with a one-year, $5 million deal in 2025, and he re-signed for 2026 for the same amount (plus the option that just declined). That history makes it seem like he’s going to look to sign for $5 million, which shouldn’t be too much for the Guardians. 

Although Rea’s number took a dip this season compared to 2025, he was arguably more valuable to the Cubs as they navigated a bevy of pitching injuries. That’s been the story of Rea’s career, as he’s good enough to pitch as a starter, but not good enough to stick as one. 

He started his career as a starting pitcher  for the Padres, and they tapped into that value at the deadline in 2026 when they dealt him to the Marlins alongside future Guardian Josh Naylor, but they sent him back after one start when he suffered an arm injury that led to him undergoing Tommy John surgery. He bounced between the big leagues and Japan after his arm healed, but the next chapter of his career didn’t really get legs until he pitched 124 2/3 innings with the Brewers in 2023. He also spent the 2024 season with the Brewers before heading to the Cubs to reunite with former manager Craig Counsell. 

While Rea would be a solid (if not uninspiring) depth rotation arm, the real benefit he could bring to the Guardians would be as a relief swingman à la Kolby Allard in 2025. The Guardians tried to soak more production out of Allard’s arm in 2026, but he barely lasted two weeks on the roster, leaving the Guardians without a true relief arm until Slade Cecconi moved to the bullpen in August. 

Again, the Guardians signing Rea wouldn’t (and shouldn’t) be the highlight of their offseason, but it would be the kind of depth signing that would help them as the 2027 season goes on.
