Crisp was hampered by a sore left wrist in the second week of the season, and a hamstring injury limited his activity most of this week.
As of Friday, "I think he's as close to 100 percent as you'll get," said manager Bob Melvin.
Crisp pinch-hit in Wednesday night's loss in Anaheim and proceeded to steal a base quickly after, showing no noticeable issue with the hamstring.
"I wasn't sure he was going to do that," Melvin said Friday. "He had a green light and he did."
Despite his early injury woes, Oakland's center fielder has four stolen bases on the year. He has also reached base safely via hit or walk in each of his eight starts.
