The Rockies called up their top right-handed pitching prospect, Jhoulys Chacin, 21, from Double-A Tulsa to shore up their bullpen, but that isn’t all the news on Thursday. Club officials confirm that they’re making a trade today for right-handed bullpen help. Stay tuned to MLB.com.

Chacin won 18 games at two Class-A levels last season, impressed the club during Spring Training and pitched well enough at Tulsa to be invited to the Futures Game during All-Star weekend.

The club has been looking to increase its talent level, but also is in need of experience. That need became greater Wednesday when right-hander Manuel Corpas annonuced that he will undergo arthroscopic surgery to remove bone chips from his throwing elbow.
