Peter O'Brien (OF, ARI) - Waiver Wire Pickups

BALLER MOVE: Deep Mixed Leagues, NL-Only Leagues

OWNED IN: 1% Fleaflicker

ANALYSIS: Peter O'Brien has long been the Diamondbacks’ most highly-touted prospect, as well as one of the most celebrated around the league. After making the transition from catcher to the outfield this year, he has warranted Kyle Schwarber comparisons. The 25 year-old O’Brien has already posted 12 HR and 32 RBI with Triple-A Reno this season to go with his impressive .306/.330/.601 line. After major injuries to both A.J. Pollock and David Peralta, Arizona's outfield is in flux. The trio of Brandon Drury, Chris Owings and Yasmany Tomas has actually been effective at times so far, but that production is unreliable in the long-term and all three guys are candidates to be designated for assignment if one begins to struggle. As soon as that happens, O'Brien will almost definitely be given another shot at big-league pitching. In just 12 MLB AB last year, O'Brien went 4-for-10 with a home run and three RBI. As soon as that promotion comes, he will be a must-own player in all leagues and undoubtedly the most added player of the week. If you have space on your bench, don't hesitate to stash.
