ANAHEIM, Calif. — Garrett Richards pitched a two-hitter for his second career shutout, Kole Calhoun hit two homers and the Los Angeles Angels beat the Boston Red Sox 3-0 Saturday night for their 13th victory in 16 games.

Richards (10-6) allowed just three baserunners and retired Boston’s final 15 hitters to wrap up the second straight shutout victory for the Angels, who increased their AL West lead to a season-best 1 1/2 games. Richards allowed just one Boston runner to reach third base, retiring 22 of 23 overall to end it.

Pablo Sandoval had both hits for the Red Sox, who have been shut out in consecutive games for the first time since Aug. 7-8, 2009.

Calhoun, who had three hits, led off the third and fifth innings with long homers into the elevated right-field stands off Rick Porcello (5-10).

Calhoun’s first career multihomer game eliminated the need for another walk-off homer by All-Star Game MVP Mike Trout, who ended the four-game series opener in dramatic fashion Friday.

Trout went 0 for 4, striking out twice and grounding into a double play.

Sandoval’s infield single and ground-rule double was the extent of the offense for the last-place Red Sox, who have lost 4 of 5 spanning the break. Boston had five hits while losing the series opener 1-0 Friday.

Porcello yielded just four hits and two earned runs in five innings, but lost his fifth straight road decision.

Batting practice was canceled while a drizzling rain hit for most of the afternoon. The tarp stayed on the field until less than an hour before game time – an extremely rare occurrence in sunny southern California.

The Angels scored a run without a hit in the second inning. David Freese reached on a grounder and advanced on another grounder and a walk before scoring on a bases-loaded wild pitch by Porcello, who needed 45 pitches to get through the first two innings.

Calhoun then hit his 11th homer leading off the third, and he added another in the fifth.

Sandoval doubled in the fifth and advanced on a groundout to become the first Boston baserunner to reach third base in the series, but Richards stranded him.

TRAINER’S ROOM

Red Sox: They addressed their bullpen depth by recalling right-hander Noe Ramirez from Triple-A Pawtucket before the game, giving them eight relievers.

Angels: Closer Huston Street said he was ready to pitch Saturday after mildly straining his groin last week. Eighth-inning specialist Joe Smith also said he was ready to pitch after taking a liner off his leg Friday.

UP NEXT

RED SOX: Eduardo Rodriguez (5-2, 3.59 ERA), the 22-year-old Venezuelan left-hander, has given up just four runs in 171/3 innings over his last three starts.

ANGELS: Stingy All-Star left-hander Hector Santiago (6-4, 2.33 ERA) looks for his first career win over Boston.
