Veteran right-hander Manny Corpas, the closer on the Rockies’ 2007 World Series team, will likely be promoted Sunday from Triple-A Colorado Springs and closer Rafael Betancourt will go on the disabled list, according to a major-league source.

Betancourt is going on the DL because of a strained right groin. Betancourt has been dealing with his groin issue most of the season and it flared up in a game May 21.

In Betancourt’s absence, Rex Brothers will likely close most games for Colorado. Brothers worked the ninth inning Saturday in the Rockies’ 7-6 10-inning victory over the Dodgers. Brothers now has 23 consecutive scoreless outings. His ERA is 0.36.

Corpas is currently not on the Rockies 40-man roster, but there is spot open on the 40-man because pitcher Edwar Cabrera is on the 60-day DL. Corpas is 2-3 with a 5.19 ERA in 34 ⅔ innings over 17 appearances for the Sky Sox. He’s walked 15 and struck out 31.
