Miller was with the St. Louis Cardinals for all of the 2009 and 2010 seasons before being traded midway through the 2011 season to the Toronto Blue Jays in the Colby Rasmus trade. Miller pitched in only six games for the Jays before being released and briefly picked up by the Boston Red Sox, where he appeared in three games, facing six batters.
