Rockies trade Rex Brothers to Cubs for pitching prospect

The Colorado Rockies have traded left-hander Rex Brothers to the Chicago Cubs for minor-league pitcher Wander Cabrera, the Rockies announced Wednesday.

Brothers, who was designated for assignment last Friday, has served as a lefty specialist out of the Rockies' bullpen for the past five seasons, compiling a 3.42 ERA and 1.49 WHIP with 61 holds over that span. He held left-handed batters to a .227/.308/.364 slash line last year.

Cabrera, an 18-year-old southpaw, registered a 4-3 record with a 2.34 ERA and averaged 10 strikeouts per nine innings over 14 appearances this year in the Dominican Summer League.
