O'Brien had another big day for Triple-A Reno, going 4-for-5 with a double, a run scored, and an RBI. O'Brien is 9-for-20 with a couple of doubles, a home run, and five runs scored to start his time in the Arizona system. He is yet to draw a walk, but that's the only downside to his performance thus far. He is making the transition from catcher to outfield, which makes his path to the majors less clear as Arizona has plenty of outfielders ahead of him, but if he keeps hitting a spot will be found for him.
