A second-round pick by the Rockies in 2010, Bettis was sent to the disabled list on July 19 after experiencing discomfort during a start against San Diego the night before. It was originally feared that Bettis, who is a key part of Colorado's group of young starters, had suffered some structural damage in his pitching elbow. But a visit with doctors on July 20 revealed just inflammation.
Bettis had previously thrown a simulated game on Tuesday. He is 5-4 with a 4.88 ERA in 13 starts this season.
