ANAHEIM, Calif. — Jason Vargas pitched a three-hitter for his first victory with his new club, Mark Trumbo and Mike Trout homered and the Los Angeles Angels beat the Baltimore Orioles 4-0 Friday night.

Vargas (1-3) threw 107 pitches, striking out three and walking two while getting 15 groundball outs. The shutout was the fourth by the left-hander in 136 career starts and his ninth complete game. He lowered his ERA to 1.63 against the Orioles in seven starts against them, his best against any team.

Vargas did not allow a hit until J.J. Hardy slapped an opposite-field single to right with two out in the fifth. The left-hander walked his next batter, Steve Pearce, on four pitches before Alexi Casilla grounded out.
