DENVER — The Colorado Rockies' beleaguered starting rotation took another blow as right-hander Jhoulys Chacin was placed on the 15-day disabled list Monday with an inflamed shoulder.
Chacin becomes the sixth starter out of commission for the Rockies. The team has already used 12 different starters this season.
The move is retroactive to Sunday.
To take Chacin's place on the roster, the Rockies recalled right-handed reliever Chad Bettis from Triple-A Colorado Springs. He will be available Monday night in Washington against the Nationals.
Chacin missed the first month of the season with a strained right shoulder. He's 1-7 with a 5.40 ERA this season.
Bettis is 0-1 with a 10.05 ERA in 13 games with the Rockies this season.
