Anaheim, CA (SportsNetwork.com) - Jason Vargas pitched six effective innings and Lorenzo Cain drove in two runs in Kansas City's 4-2 win over the Angels in a rematch of last season's American League Division Series.
Kendrys Morales homered against his former team and the reigning AL champions moved to 4-0 for the first time since 2003 when they won their first nine games of the season.
Vargas (1-0) allowed five hits and a pair of runs while fanning three. Jason Frasor and Kelvin Herrera each pitched a scoreless frame to bridge the gap to Wade Davis. The closer struck out three batters in the ninth to pick up his first save.
"Jason threw great. He executed his pitches and kept them off-balance. Defense is a big part of our game and it was tonight," Royals manager Ned Yost said.
Hector Santiago (0-1) gave up six hits and three runs over 5 1/3 innings for the Angels, who won their final two contests of a season-opening series at Seattle.
"Hector struggled with his first 50 pitches, then he found his rhythm," Angels manager Mike Scioscia said. "He used a lot of pitches early, but he'll be better next time."
Cain singled to center to drive in Alcides Escobar in the fifth to give KC a 2-1 edge.
Morales then homered to left-center to lead off the sixth before David Freese went deep in the bottom of the frame.
Johnny Giavotella struck out swinging to strand pinch-hitter Matt Joyce, who doubled in the home seventh.
Freese grounded out with a runner in scoring position in the eighth and the Royals tacked on a run in the ninth when Fernando Salas walked Cain with the bases full.
The Angels, who were swept in last year's ALDS, fell to 23-32 in home openers ... The Royals were 2-for-10 with runners in scoring position.
