Montgomery will start Saturday's game in Colorado, WSCR-AM radio's Bruce Levine reports.

EDGE Analysis

John Lackey's start is getting pushed to Tuesday so that he can rest his ailing shoulder, so Montgomery gets the spot start. This will essentially be a tandem start with Mongomery pitching the first three or four innings and Trevor Cahill coming on to pitch the next three or four before handing it to the late-inning arms. Montgomery hasn't logged more than two innings in an outing since July 17, which, coupled with the fact he'll be pitching in Coors Field, makes him fairly useless in most formats Saturday.
