The Rockies added outfielder Matt Holliday to the disabled list on Sunday because of an injured hamstring, according to The Denver Post. He was replaced on the team's roster by Cory Sullivan, who was called up Sunday from Triple-A Colorado Springs. "I felt it grab a little bit; we'll see how it feels," Holliday said Saturday after injuring it in a loss to the Mets. "It's tough to tell right now; I've got ice all over it." Colorado is already without Brad Hawpe, Clint Barnes, Troy Tulowitzki, Luis Vizcaino, and Jason Hirsh.
