Rockies manager Jim Tracy has announced that Alex White will replace Jason Hammel in the rotation on Tuesday against the Astros. We predicted as much after Hammel was torched again Friday for six runs over three innings of work, pushing his post-All-Star break ERA all the way up to 8.41. Hammel will moved into a bullpen role but might eventually have a shot to break back into the rotation if Esmil Rogers doesn't turn things around.
