Colorado Rockies shortstop Troy Tulowitzki had surgery on his left groin on Thursday to remove scar tissue and will miss at least six weeks.
Tulowitzki, who has been sidelined since May 30, was hitting .287 with eight homers and 27 RBIs in 47 games this season.
The Rockies have been reeling without their two-time All-Star in the lineup, losing 12 of 13 games entering Thursday's contest against the Philadelphia Phillies.
''We know that he has peace of mind in knowing that what it was that he was dealing with is now fixed, and the time frame is not longer than initially anticipated after doing the tests and looking at MRIs and things like that,'' Colorado manager Jim Tracy said. ''We're very encouraged in relation to the news that we got.''
