Barrero appeared in 22 games at the big-league level with St. Louis in 2025, but he finished last season in the Orioles organization as a member of the Norfolk roster and will return to the affiliate to begin the 2026 campaign. The 27-year-old came up short in his bid for a utility spot on the Orioles' Opening Day roster after slashing just .105/.150/.289 over 40 plate appearances during the Grapefruit League.

Barrero split time in 2025 between the Cardinals and Orioles organizations and appeared in 22 games at the big-league level, all of which came with St. Louis. After being dropped from the Cardinals' 40-man roster in late June, Barrero elected free agency and caught on with the Orioles on a minor-league pact. He proceeded to spend the rest of the season at Triple-A Norfolk, slashing .190/.261/.344 with eight home runs and nine stolen bases across 218 plate appearances. While his new minor-league deal could include an invitation to major-league spring training, the 27-year-old utility man should be viewed as a long shot to win an Opening Day bench role with Baltimore.
