HOUSTON -- Wade Miller will resume pitching after the All-Star break to give his right shoulder time to heal.
Miller, who is coming back from arthroscopic surgery on his shoulder in late September, made his third rehab start on Monday for Class A Peoria.
"My arm doesn't hurt," Miller said Wednesday. "It's just a matter of the ball isn't coming out of my hands real good right now.
"I've got to find a way out, and how it's going to work," he said. "I haven't figured it out yet. My arm just feels fatigued right now and hopefully a little rest will help."
He will have a throwing session in the bullpen this weekend in Milwaukee, and hopes to make another rehab start for Peoria after the break. His velocity has increased each outing but Miller said, "It's just not where I need to be."
He still expects to pitch this season for the Cubs.
"I hope so," Miller said. "I'm trying right now, and we'll see where it goes."
