O'Brien went 3-for-4 with his fourth home run of the season Monday for Triple-A Reno. He scored twice and drove in two runs. O'Brien keeps hitting, raising his line to .404/.429/.766 after this performance. The question remains whether he can field a position well enough to stick in a major league lineup. He played left field in this one, while the D-Backs maintain that the move to the outfield isn't permanent and he can be expected back behind the plate in the coming weeks. Of note, O'Brien is still yet to draw a walk this season through 49 plate appearances.
