Rockies manager Walt Weiss said Wednesday that Tyler Colvin and Corey Dickerson will share time in center field while Dexter Fowler is out. Colvin entered play Wednesday in a 2-for-32 (.063) slump since June 17, but Weiss thinks he's "taken some good swings lately." Dickerson has hit a whole lot, either, sporting a .235/.316/.471 in seven contests since his call-up. Both players hit left-handed, so it won't be a strict platoon but rather a "mix and match" situation, according to Weiss.
