Corpas fares well vs. Cubs in bullpen battle

MESA, Ariz. -- With a strong two-inning outing against his former club, Rockies non-roster invitee Manny Corpas was impressive Wednesday in his bid to earn a middle relief spot.

Corpas, who went 0-2 with a 5.01 ERA in 46 2/3 innings for the Cubs last season, fanned two in two perfect innings. In Denver, Corpas is better known as the closer on the 2007 squad that went to the World Series.

Corpas would lose the closer job as elbow problems began to derail him. After missing 2011 because of surgery, Corpas returned to the Majors with the Cubs last season.

The Rockies plan to carry three relievers who are capable of facing one batter or pitching multiple innings to pitch in the middle roles, and there is no shortage of competition.

"There's good competition," Rockies manager Walt Weiss said. "For the most part, they've thrown the ball well. There will be tough decisions at the end of spring, but that means we're getting better as a ballclub. Corpas is a sinker-slider guy who knows what he's doing. He's wily out there. He knows how to attack hitters."
