Background
Growing up in Bocachica, Colombia, Guerrero didn’t have access to the polished academies that feed so many prospects into affiliated ball. His path to the majors was the one most Latin American players know well: relentless work, minor-league seasoning and a willingness to wait for his shot. When he debuted on May 17, 2016, he joined a short list of Colombian pitchers to reach MLB — and he’s stayed there.
Professional Career
Guerrero has spent most of his career working out of the bullpen. His time with the Miami Marlins (2018–2019) was a mixed bag. In 2018 he threw 58.0 innings with a 5.43 ERA and 68 strikeouts. The following year things got tougher: a 6.26 ERA over 46.0 innings with 43 punchouts.
Those numbers didn’t tell the whole story. Guerrero kept working, and signing with Boston in 2026 gave him a fresh canvas. The results have been sharp: in 27.0 innings with the Red Sox he owns a 2.33 ERA, a 1.04 WHIP and 30 strikeouts — his best stretch in years.

Awards and Milestones
Guerrero hasn’t collected a Cy Young or a Gold Glove, but staying in the big leagues for more than ten years as a Colombian pitcher is an achievement that needs no trophy. Only a small fraction of Latin American players reach MLB — fewer still stick around long enough to reinvent themselves the way Guerrero has in Boston.
Worth Noting
At 35, Guerrero is still getting hitters out at the highest level while many pitchers from his draft class have already hung up their cleats. Whatever he’s doing in Boston, it’s working — and it’s a reminder that longevity in this game is its own kind of excellence.
