Baseball's career saves leader twisted his right knee while shagging fly balls near the outfield wall during batting practice. Rivera grimaced in pain as he was loaded onto a cart and taken from the field. Results of an MRI exam were not available by the game's conclusion. Danny Duffy (2-2) pitched well into the sixth inning before turning the game over to the Royals bullpen, which held the Yankees in check until Jonathan Broxton came out for the ninth.
