7 years agoThe Miami Marlins acquired power-hitting first baseman Peter O'Brien from the Dodgers for cash on Friday, according to South Florida Sun-Sentinel writer Matthew DeFranks. O'Brien averaged almost 22 home runs a year over six seasons in the minors, and this season he already has seven home runs in 112 plate appearances. While the power is legitimate, his batting average will be what kills most of his fantasy value. After hitting .284 in 2015, his average has dropped every year since, hitting a career low last season at .191, and he is dropping even further, as he is currently batting .150 at Double-A. In 16-team mixed and NL-only leagues, he might be worth picking up for his power potential if he gets called up, but most likely he won't have any relevance in fantasy this year.--Michael Grennell - RotoBaller
