O'Brien went 1-for-4 with a three-run home run on Monday for Triple-A Reno, his first home run of the season.

EDGE Analysis

O'Brien slashed .284/.332/.551 with 28 home runs and 107 RBI at Triple-A Reno last season, and he was one of the last cuts from the big league roster this spring, so the 25-year-old shouldn't be too far from a call up if he continues to play well in the minors. He still figures to need work defensively in the outfield, as he came up through the minors mainly as a catcher. He's started all three games so far this season in left field.
