Fowler was on crutches on Thursday, but has improved dramatically since then.
"To see him getting taped up [for batting practice], you have to tip your cap to this guy," Rockies manager Jim Tracy said. "He bounces back very quickly. He has a fairly high threshold for pain. He sprained that ankle good.
"The silver lining was, for whatever reason, he didn't swell up much. If we were trying to get swelling out of that ankle, he'd be still up there with his foot in a bucket of ice -- trying to get swelling out so then it can be massaged, then you can get tape on it and possibly get him out here walking around. He would have more than likely been on the disabled list."
