The Quakes dropped the first game of the best-of-five, second-round series with the Lake Elsinore Storm, a Padres affiliate, 5-0, on Saturday. Another rehabbing starter, Chris Young, threw 5 2/3 scoreless innings for Lake Elsinore.
Angels manager Mike Scioscia said that Trevor Bell's eventual role, be it as a reliever or starter, has yet to be determined. Bell is to leave the rotation upon Pineiro's return, and has gone 2-5 with a 4.72 ERA in 25 games, seven of them starts.
"He has the upside to being a real good Major League starter," Scioscia said. "We'll see how things evolve as far as the makeup of our team."
Scot Shields is unavailable for a fourth straight game after he left Tuesday night's contest with stiffness in his right (throwing) elbow. He has not gone for tests but the Angels feel the injury is not serious.
