Double-A Frisco reinstated Walcott (concussion) from the 7-day injured list Wednesday, Shawn McFarland of The Dallas Morning News reports.
Walcott landed on the IL on Aug. 2 after he was struck in the head by a pickoff throw a day earlier, but he's since passed all concussion tests and has received the green light to return to action at Frisco. The 20-year-old prospect has performed well since making his season debut at Frisco on July 17, slashing .308/.357/.577 with three home runs and three steals through 56 plate appearances. He's thus far been limited to serving as a designated hitter after undergoing internal brace surgery on his throwing elbow back in February.
