ANAHEIM (AP) — Johnny Giavotella hit a three-run shot for his first homer with Los Angeles after the second inning was extended by a replay review, and the defending AL West champion Angels so thoroughly roughed up the Athletics 14-1 Tuesday night that Oakland first baseman Ike Davis pitched.

Kole Calhoun tied a career-best with four hits, including a three-run homer for the Angels.

Giavotella had a career-high four RBIs. He was acquired in a trade from Kansas City in December and won the second base job in spring training after Howie Kendrick was dealt to the Dodgers.

Davis had a 2.25 ERA at Arizona State, and he impressed in the eighth Tuesday. The lefty, son of reliever Ron Davis, retired Collin Cowgill, C.J. Cron and Chris Iannetta with groundballs, tossing only nine pitches.

Hector Santiago (2-1) allowed a run and three hits in six innings and struck out eight.

Drew Pomeranz (1-2) gave up five runs — four earned — and eight hits in five-plus innings and fanned six.

The left-hander thought he was out of the second inning unscathed, after third baseman Brett Lawrie charged Cron’s slow bouncer up the line and got the force at second on Erick Aybar before Eric Sogard relayed to first. Cron was called out by umpire Mike Muchlinski, but Angels manager Mike Scioscia asked the crew to take a second look and Cron was declared safe.

Pomeranz ended up making 25 extra pitches that inning and gave up four runs before getting the third out. Giavotella homered on a full count.

Calhoun then singled, Mike Trout walked on four pitches, and Calhoun scored the fourth run when shortstop Marcus Semien misplayed Albert Pujols’ grounder for his fifth error in 15 games.

Billy Butler got the A’s on the board in the third with a two-out homer, their last hit until Mark Canta’s one-out infield single in the eighth.

But Pomeranz was charged with another run after Cron chased him with a leadoff double during a six-run sixth that included three errors by the A’s and increased the Angels’ lead to 10-1.

Giavotella singled in his fourth RBI in the inning.

TRAINER’S ROOM

Athletics: 2B-OF Ben Zobrist missed his second straight game because of an injured left knee.

Angels: Scioscia said OF Josh Hamilton (shoulder) is close to beginning an extended spring program in Arizona.

UP NEXT

Athletics: RHP Sonny Gray (1-0) faced the Angels in three of his final eight starts last season, going at least seven innings each time. He is coming off a no-decision at Kansas City in which he gave up four runs and 11 hits over six innings.

Angels: RHP Jered Weaver (0-2) had a 6.61 ERA in his first three outings. The 10-year veteran and me All-Star, who won 18 games last year, has never gone winless in his first four starts of a major league season.
