The Pirates walked-off the Kansas City Royals Monday night 7-6. Bucs catcher Jacob Stallings two-out RBI single in the bottom of the ninth inning rallied the Pirates past the Royals. Stallings has spent the last three years shuttling between Pittsburgh and Triple-A Indianapolis while stuck on the organizational depth chart behind Francisco Cervelli and Elias Diaz. Edgar Santana got the win with a 1-2-3 ninth.
