Mike Moustakas homered leading off the 11th inning, and the Kansas City Royals kept rolling in their first postseason in 29 years.

They posted a 3-2 victory over the Los Angeles Angels in the AL Division Series opener Thursday night.

Moustakas hit the first extra-inning homer in postseason history for the Royals, a high shot off Fernando Salas that barely reached the elevated right-field stands at Angel Stadium.

Alcides Escobar had an early RBI double for the Royals, and their bullpen repeatedly escaped trouble in Kansas City’s first game since that spectacular, 12-inning comeback victory over Oakland in the wild-card playoff Tuesday night at Kauffman Stadium.

Game 2 in the best-of-five series is Friday night at the Big A, with Angels 16-game winner Matt Shoemaker taking on fellow rookie Yordano Ventura.
