Fantasy Impact

O'Brien has started the last four games over Derek Dietrich and has been hitting very well. Over those last four starts, he is 6-for-12 with two runs and five RBI. He's got a hot bat and could help you in a playoff push but make sure he's in the Marlins starting lineup.

Fantasy Impact

O'Brien flashed his power for the second time in three games and the third time in seven games. He's been very boom or bust lately and could be worth a look since he is hot. For now, he's home run dependent but could produce runs in other ways with a hot bat.
