"I threw my fastball in and out which worked well and the curveball kept them off-balance," said O'Brien. "I usually throw my changeup a little more but I didn't need it today."
His velocity, which was consistently 84-86 during the outing, appeared to be even harder.
"I get that lot," said the lefty, when told that his velocity looked faster than he was actually throwing. "Being 5-11, people don't expect me to throw too hard. They say I hid the ball really well, which causes it to kind of jump on people. And I have a pretty vicious arm action."
So far, quite a few colleges have taken notice of the 5-11, 185-pounder, many of whom were at his game.
His offer list, while not as large in number, is still pretty impressive.
"I've received offers from NC State, East Carolina, Duke and Marshall," said O'Brien.
As of now, he has his list of schools narrowed down to six.
"I've got it down to North Carolina, Duke, NC State, East Carolina, Wake Forest and Louisville," said O'Brien.
It's possible other schools could also jump in the picture such as Mississippi State, a team that had one of its assistant coaches watching O'Brien during his Tuesday outing.
"I'm waiting for their offer," said O'Brien. "I really enjoyed talking to (assistant) Coach (Butch) Thompson on the phone. He is a great guy who really knows what he is talking about. I look forward to talking to him some more."
But Mississippi State, if they are going to offer, better do it soon because O'Brien is close to making his college choice.
"I am going to make my decision in about two weeks," he said. "I'm going to spend another week here (at the 2010 WWBA 17U National Championship), throw one more time in the complex, then look at all my offers, put everything on the table and make my decision the following week."
He talked about the things he is looking for in a college.
"I want to go to a bigger school and I want to go down south," said O'Brien. "I also want to go to a place that has a good baseball reputation and a place where I think I can play early."
No matter what his decision is, he's grateful to all the coaches who have recruited him.
"All the coaches that I have talked to have been great people and I learned a lot from them," said O'Brien. "During the recruiting process, they have made it a lot easier."
