The Rockies recalled Hughes from Triple-A Albuquerque on Wednesday, Thomas Harding of MLB.com reports.
Hughes is receiving his first promotion to the major leagues. The 24-year-old has posted a 5.31 ERA, 1.28 WHIP and 48:11 K:BB in 40.2 innings with Albuquerque this year. The right-hander is expected to initially work out of the bullpen despite starting in seven of his nine appearances in Triple-A. The Rockies designated John Brebbia for assignment to make room on the roster for Hughes.
