The Colorado Rockies will place closer Rafael Betancourt in the 15-day disabled list with a right groin strain and will reportedly purchase the contract of reliever Manny Corpas from Triple-A Colorado Springs, according to Patrick Saunders of the Denver Post.
Betancourt initially tweaked his groin on May 21 in a win over the Arizona Diamondbacks. Since then, he's made three appearances and allowed four runs on four hits and a walk while getting charged with a pair of losses, raising his ERA to 3.20. Betancourt hasn't been quite right all year; although he boasted a 1.56 ERA at the time of the injury, he has already walked nine batters in 2013, more free passes than he issued in all of 2010 and 2011 and just three fewer than in 2012.
Corpas, 30, served as the Rockies' closer in parts of three different seasons, most notably in 2007, when he was nearly unhittable down the stretch during the team's World Series run. He owns a 5.19 ERA with 31 strikeouts and 15 walks in 34.2 innings with the Sky Sox this season. Corpas will assume a middle relief role with the Rockies, according to Saunders, with Rex Brothers likely to move into closer's spot while Betancourt is out.
No corresponding move will be needed for the Rockies to place Corpas on the 40-man roster, as the team currently has an open spot.
