DETROIT -- Tigers rookie Dixon Machado stood in the on-deck circle, his emotions ranging from cool and collected to surges of nerves.
The shortstop wasn't sure if he'd have an opportunity to bat in the bottom of the 12th inning. If he did, Machado knew it would be in a tie game with two out and the bases loaded. With a win and his first Major League walk-off hit at stake, Machado delivered a single down the left-field line to give the Tigers a 5-4 win in 12 innings over the Royals on Friday night.
