The Kansas City Royals placed shortstop Bobby Witt Jr. on the 10-day injured list for the first time in his major league career.

Kansas City Royals All-Star shortstop Bobby Witt Jr. left Monday night’s 4-3 victory over the San Francisco Giants with back tightness, which also kept him out a day earlier.

The Royals already appeared set to sell at the upcoming trade deadline, but losing their top hitter only reinforces that position.
