Renfroe (hamstring) hit on the field and ran the bases at Kauffman Stadium on Monday, MLB.com reports.
The Royals have yet to decide whether Renfroe will go out on a rehab assignment, but regardless, he is tracking toward a return from the 10-day injured list as soon as this weekend, just a few days after he's first eligible for activation. Renfroe has seen virtually all of his playing time this season in right field, but with Tommy Pham recently being added to the roster and with Vinnie Pasquantino (thumb) out for the season, the Royals could consider using Renfroe some at first base, where he has a bit of experience.
