Cole, the manager of the Colorado Spring Sky Sox, noticed that Tulowitzki isn't 100 percent.
"It's going to take some time for something like (groin surgery) to heal up," Sky Sox manager Stu Cole said. "He has a ways to go after that surgery."
Sunday, the Rockies' shortstop played the five innings he was scheduled for in the Sky Sox's 5-3 win over Las Vegas, but Cole says the star isn't back to full strength.
"You can't expect a guy to be 100 percent after a surgery like that," Cole said. "It's not realistic. It's just going to take some time.
The Rockies announced Monday morning that Tulowitzki will serve as Colorado Springs' designated hitter on Monday, and will then continue his rehab with the Tulsa Drillers on Wednesday and Thursday.
Tulowitzki hasn't appeared in a game with the Rockies since May 30. Colorado's All-Star shortstop was enjoying a solid year, hitting .287/.360/.468 with eight home runs, before hitting the disabled list.
