CHICAGO -- Jason Bulger worked out so well, the Angels decided to summon another power arm for their bullpen on Sunday for the series finale against the White Sox.

Kevin Jepsen, who contributed handsomely to Team USA's bronze medal finish in the Beijing Olympics, was en route to U.S. Cellular Field as the Angels got ready to face the big guns from the South Side.

"We just need one arm now," Angels manager Mike Scioscia said, having taxed his bullpen in a 15-inning affair that went Chicago's way on Saturday night when Jim Thome took Justin Speier deep. "The rest of the guys will be with us tomorrow."

The Angels return home to face the Yankees on Monday night with some unnamed Minor League reinforcements on their way.

Jepsen, 24, throws in the mid-90s with a power breaking ball -- the same equipment Bulger used to make a dazzling season debut on Saturday night. Retiring all nine men he faced in extra innings, Bulger struck out five.

"He's a kid who came into the organization, really threw hard, had a setback with his shoulder and came back," Scioscia said of Jepsen, a second-round pick in the 2002 First-Year Player Draft out of Bishop Manogue High School in Reno.

A native of Anaheim, Jepsen missed most of the 2005 season with his shoulder injury and spent the '06 and '07 seasons at Class A Rancho Cucamonga. He put it all together this season at Double-A Arkansas (2-1, 1.42 ERA in 31 2/3 innings), earning a promotion to Triple-A Salt Lake, where he also impressed with a 2.35 ERA across 23 innings.

That earned him a ticket to China, where he was an anchor in manager Davey Johnson's bullpen.
