Colorado Rockies shortstop Troy Tulowitzki left the game Tuesday night against San Francisco in the first inning with a strained left quadriceps muscle.

Tulowitzki, a late lineup addition after Jeff Baker was scratched due to a broken blood vessel that happened during pregame warmups, left after bending over to try to stop Aaron Rowand's single. Tulowitzki grimaced and grabbed his left hip and lower back area. He then walked gingerly off the field.

The Rockies' athletic trainer first checked on Tulowitzki after he threw to first base on Eugenio Velez's grounder that was dropped for an error, three batters earlier.

Manager Clint Hurdle had to get creative to have a healthy infield.

Clint Barmes moved from second to shortstop. Garrett Atkins moved from third to make his major league debut at second base, while Chris Iannetta entered the game to play third for the first time in his big league career.

Iannetta then hit a solo home run leading off the second to tie the game at 2.

Tulowitzki finished second in the National League Rookie of the Year voting last season, hitting .291 with 24 homers and 99 RBIs. He was off to a very slow start, batting .152 with one homer in the his first 25 games.
