The Rockies have placed hot-hitting Kaz Matsui on the 15-day disabled list with back spasms.  Matsui was off to a .361 start with a .867 OPS in 9 games this season.  He also has scored 6 runs, knocked in 3 and had 5 stolen bases already this season.  Jamey Carroll will likely take over for Matsui while he’s injured.  Carroll also is off to a fast start this season with a .389 batting average and a .976 OPS in his first 7 games.  He also has scored 5 runs and knocked in 2 so far this season.  The Rockies also recalled Clint Barmes to replace Jamey Carroll as the utility man.
