SAN FRANCISCO — The Colorado Rockies activated right-hander Rafael Betancourt from the disabled list before Friday night's game against the San Francisco Giants.
Betancourt was 2-2 with a 6.30 ERA before going on the DL with symptoms of vertigo.
To make room on the roster, the Rockies sent right-hander Justin Miller to Triple-A Albuquerque. Miller was 1-0 with a 2.08 ERA.
Rockies manager Walt Weiss said he told Miller he remains in the mix.
