ANAHEIM -- Mike Moustakas didn't hear any "Moose" calls during his Major League debut, but he surely heard them on Saturday night when he belted his first home run for the Royals.

"I might've," Moustakas said. "I don't know."

What Moustakas does know is that he hammered the first pitch to him from Angels right-hander Joel Pineiro in the fourth inning into the right-field seats of Angel Stadium. Several moose calls serenaded the Los Angeles area product as he circled the bases.

"It feels good to be able to do that in front of my family and friends," he said. "It felt good coming off the bat, but it's a shame we didn't end up with a 'W' tonight."

The blast was Moustakas' second career hit. In his debut in Friday night's 4-2 victory, he got a broken-bat single in his third trip to the plate. In Saturday night's 7-5 loss, he again went 1-for-3, giving him a .333 batting average in his first two games.

His home run came with the bases empty and two outs, cutting the Angels' lead to 5-3. He also popped out, walked and struck out.

Fellow rookie Eric Hosmer hit his first home run in his sixth game, also a solo shot, against A.J. Burnett at Yankee Stadium on May 11. He has five in his first 34 games.
