Making his first Major League start, Aumont buried the Phillies quickly in Friday's 12-4 loss at Citizens Bank Park. He allowed five hits, six runs, two home runs, walked seven, threw one wild pitch and threw behind one batter in four innings. He struck out three.
He threw 104 pitches, just 56 for strikes.
"I don't give up," Aumont said. "I'll keep working. I know I can do it. I've done it plenty of times."
Aumont joined the Phillies in December 2009 as part of the Cliff Lee trade with Seattle. The Phillies moved him from the bullpen to the rotation the following spring, but after struggling as a starter in the Minors, he returned to the bullpen.
