The White Sox have added veteran reliever Javy Guerra on a minor league agreement, according to his transaction tracker on MLB.com. Atlanta’s Triple-A affiliate released the right-hander on Thursday. It didn’t take long for Guerra to find a new club.
Guerra had spent the past two seasons with the Hanshin Tigers of Japan’s Nippon Professional Baseball. He returned to the States this year, inking a minor league deal with Atlanta in January. The righty was tagged for five earned runs over 2 2/3 innings in Spring Training. Guerra scuffled to a 5.68 ERA across 16 appearances with Gwinnett. He had three more walks (20) than strikeouts (17).
The 30-year-old Guerra has spent parts of five big-league seasons with three teams. He most recently pitched with the Rays in 2023. The majority of Guerra’s innings in the majors have come with the Padres. He debuted with San Diego in 2019 and was an occasional member of the bullpen for four seasons.
Guerra has an ERA well above 6.00 as a big leaguer. Walks have typically been his biggest issue. He’s issued free passes at a massive 14.3% clip over 63 MLB innings. Guerra did put together a strong campaign with Hanshin in 2024. He fired 58 innings with a 1.55 ERA. The righty recorded 14 saves. More importantly, he trimmed his walk rate to 4.9%. Guerra only pitched in six games during his second season with Hanshin.

He has a cool name
He is a former padre
Go padres!
Why sign this guy you’d be better off signing someone like Brett de geus or Luis Frias out of the Mexican league if you are looking for depth.
But Bauer cant get a shot… smh
Screw Manfred, just sign the guy.
Bauer had a shot. As you may or may not recall, aspects of it were suboptimal.
Can’t be any worse than Griffin Canning or Matt Waldron
Rock and Burke walked 10 batters yesterday!
Can this guy throw strikes?
Burke didnt have it and they are playing a very good offense that is finding is stride. Rock is… who knows, but you gotta give him more than one game against the Dodgers to find out.
Sox used to have someone named Javy Guerra about 16 years ago. Thought it was the same person.
I thought he retired like 5 years ago
