KANSAS CITY, Mo. —

The Kansas City Royals added a pair of big-league pieces to their roster Sunday, acquiring outfielder Isaac Collins and right-handed reliever Nick Mears from the Milwaukee Brewers in exchange for left-hander Angel Zerpa.

Collins, 28, gives the Royals a versatile outfielder coming off his first full major league season.

A switch-hitter who played mostly left field in 2025, Collins posted a .263 batting average with a .368 on-base percentage and a .411 slugging percentage for Milwaukee. He hit nine homers, drove in 54 runs and stole 16 bases while appearing in 130 games, finishing with 2.1 WAR and a 118 OPS+.

Mears worked exclusively in relief.

The 29-year-old posted a 3.49 ERA across 63 appearances last season, limiting baserunners and giving Milwaukee reliable innings out of the bullpen.

Over six major league seasons with Pittsburgh, Colorado, and Milwaukee, Mears has struck out 174 batters in 164 innings, averaging 9.5 strikeouts per nine innings.

The deal sends Zerpa to Milwaukee.

The 26-year-old left-hander appeared in a career-high 69 games for Kansas City in 2025, posting a 4.18 ERA.

Zerpa was originally signed by the Royals as an international free agent in 2016 and spent his entire professional career in the organization before the trade.
