The Royals placed Witt on the 10-day injured list Wednesday due to low back tightness.
The durable Witt will go on the IL for the first time in his five-year career in the majors after he was held out of the lineup for Sunday's loss to the Padres due to the back issue and then aggravated the injury while returning to the starting nine for Monday's win over the Giants. The Royals haven't indicated that Witt's injury is any sort of long-term concern, so if he responds well to a week and a half of rest, he could be ready to come off the shelf when first eligible July 31. Tyler Tolbert and Andrew Velazquez are likely to share time at shortstop while Witt is out.
