The Indians selected Nellie Rodriguez in the 15th round of the 2012 draft out of George Washington HS in New York City. That high school should ring a bell, for in 1991 the Indians drafted another young hitter from Washington HS that you might remember.
Rodriguez spent most of his time as a catcher in high school, but moved to first base full-time after turning pro. The Indians promoted him fairly aggressively through the low minors, sending him to Lake County to start the 2013 season. He struggled there, and ended the campaign in Mahoning Valley, but his second go-round in Eastlake was met with success (.268/.349/.482). He moved to Lynchburg in 2015, and after blasting 17 home runs in 460 plate appearances, ended the year in Akron. He struggled against AA pitching (.118/.200/.269), though.
Rodriguez is a big man, and he can hit a baseball as far as anyone in the organization. But with that impressive power comes trade-offs, notably a bevy of strikeouts that could indicate trouble at higher levels. He's an above-average defender at first base, but it's going to be his power/hit tools that could make or break his major-league chances. His swing, at least at the beginning of last season, had some holes in it, according to Baseball Prospectus, though, again, he didn't have any problems with the Carolina League.
Rodriguez still has some time on his side, though, as he'll start the 2016 campaign in Akron at the relatively young age of 21.
