The All-Star shortstop called it "fatigue" and said it wasn't anything to worry about, even with his injury-riddle past. He left Friday's game in Los Angeles against the Dodgers after aggravating his leg while trying to beat out a bouncer.
He said he knows fans hold their breath whenever he takes a day or two off. He was limited to 91 games last season before undergoing hip surgery.
Tulowitzki compared his situation to that of Derrick Rose and the injuries of the Chicago point guard, saying "if you talk to the Bulls fans, they think the same thing about D-Rose until he was out there on the field."
