BALTIMORE (AP) – Alex Gordon hit a tiebreaking homer in the 10th inning, Mike Moustakas added a two-run shot and the Kansas City Royals defeated the Baltimore Orioles 8-6 Friday night in the opener of the AL Championship Series.

Earlier, Gordon doubled in three runs, was picked off first base, made a great catch in left field and got hit in the neck with a pitch. His homer off Darren O’Day sent the Royals toward their fourth extra-inning victory in five games this postseason.

The Orioles tried to rally in the 10th. Pinch-hitter Delmon Young hit an RBI single with two outs, but closer Greg Holland retired Nick Markakis on a grounder with two runners on for the final out in the rain shortly before 1 a.m.
