O'Sullivan struggles as he works on delivery
SURPRISE, Ariz. -- Sean O'Sullivan didn't have much luck of the Irish as he pitched five innings in a Minor League intrasquad game on St. Patrick's Day.

He gave up seven hits and seven runs (six earned) with one walk and four strikeouts. The problem was that he regressed a bit in his effort to overhaul his delivery, according to pitching coach Bob McClure.

"On the good side, he pitched well, but he was leaving too many balls up that were easy to get to," McClure said. "He's still got to stay down in the zone more. That's the main focus for him, just pitching at the knees like he did against San Diego and staying down there. Up has got to be only by design; I'd rather he'd just be down, down, down."

McClure and O'Sullivan eliminated what was termed a pause in his motion and that was deemed a success.

"We saw the difference -- that was night and day. So you know it's right -- it's one motion -- boom. It's shorter. ... He had no trouble keeping the ball down when he was doing it right," McClure said.

So more repetitions of the motion are ahead for O'Sullivan.

"It's got to be something to where he doesn't even think about it; he's just doing it," McClure said. "And that takes a lot of reps."
