Manny Corpas, Jeremy Affeldt and Jeff Francis have all been pretty good this season.  Corpas has been the main set up man early in the season but he’s getting a mini-audition as the closer because Brian Fuentes has had a rough time as of late.  Corpas is 3-2 with 1 save, a 2.51 ERA and a 1.19 WHIP so far this season.  Look for Corpas to return to the set up role soon and for him to do a good job in the 2nd half of the season.  Jeremy Affeldt has always had the talent but he has never converted that into results until this season.  He is 4-1 with a 2.50 ERA and a 1.17 WHIP so far this season.  Affeldt has only allowed 22 hits in 36 innings this season and he could turn into a dominant relief pitcher if he can tighten up his control as he has walked 20 batters this season.  Jeff Francis is turning into the ace the Rockies have expected him to.  He is 8-5 with a 3.87 ERA and a 1.38 WHIP so far this season.  The Rockies will need him to keep up the good work if they are going to make the playoffs.
