DENVER (AP) - The Colorado Rockies have placed shortstop Troy Tulowitzki on the 15-day disabled list because of a left groin strain.
Tulowitzki felt pain after running out of the batter's box when he grounded out to second base during the Rockies' six-run sixth inning against Houston on Wednesday. He left the game after that.
He underwent an MRI on Thursday and the team was awaiting the results.
The All-Star shortstop said after the game he had hoped to avoid going on the disabled list but the team decided to make the move before Thursday's series finale against the Astros.
Tulowitzki, on a nine-game hitting streak, has 13 RBIs in Colorado's last 11 games.
The Rockies activated infielder Chris Nelson from the 15-day DL to take Tulowitzki's spot on the active roster.
