Santiago squared around to bunt on an 0-1 pitch, but replays showed he pulled the bat back as the pitch came in. The ball hit Santiago on his right leg. Home-plate umpire Brian Runge ruled it a foul ball, resulting in an 0-2 count.
Santiago grounded out to first on the 1-2 pitch. Detroit's next batter, Gerald Laird, reached base on a one-out walk, but Westbrook retired Austin Jackson and Quintin Berry from there.
"I was shocked," Santiago said. "[If] he called me swinging or something, maybe I could take that better, but no, not a foul ball. That's not even close. My bat's over here. The ball hit me in the leg. Come on."
