In 32 career Major League games, all with Colorado, Scahill is 1-0 with a 4.56 ERA (47.1 ip, 24 er), 16 walks and 26 strikeouts. The Winfield, IL native was originally selected by Colorado in the 8th round of the 2009 First-Year Player Draft out of Bradley University.

Chacin, 26, was originally placed on the disabled list on June 30 (retroactive to June 29) with right shoulder inflammation and has made 11 starts for Colorado this year after missing the first month of the season with a right shoulder strain. He has gone 1-7 with a 5.40 ERA (63.1 ip, 38 er) with five quality starts for the Rockies. The Maracaibo, Venezuela native is a veteran of five Major League seasons (2009-13), all with Colorado.
