"He made a lot of improvement yesterday," Rockies manager Walt Weiss said. "He came in today feeling even better."
Tulowitzki felt some tightness in his groin Thursday after legging out an infield single in the sixth inning of a 3-2 loss to the Dodgers. After a brief discussion with Weiss, Tulowitzki talked his way into remaining in the game. Weiss said he would have used a pinch-runner had Tulowitzki reached base again.
Weiss also said Tulowitzki was available as a pinch-hitter the past two games.
Tulowitzki entered Sunday leading the Majors in average (.350), on-base percentage (.441) and runs (66). His 18 home runs were the second most in the National League behind the Marlins' Giancarlo Stanton.
Starting in Tulowitzki's place the past two days, Josh Rutledge had one hit and six strikeouts in eight at-bats. He scored a run Saturday but also registered a throwing error.
