Kevin Goldstein's write-up at Baseball Prospectus: DOB: 4/1/91 Height/Weight: 6-2/195 Bats/Throws: R/R Drafted/Signed: 2007, Dominican Republic 2010 Stats: .292/.375/.359 at Low-A (109 G) Best/Worst Tool: Speed/defense Year in Review: This teenage Dominican recovered from a slow start to put up impressive numbers at Low-A. The Good: Puello is arguably the best athlete in the system. He's a plus-plus runner, and some scouts project some power for him down the road based on his size and strength. His arm is another plus tool, and he made some adjustments to his swing as the season went on, leading to more consistent contact. The Bad: The debate over Puello's power is wide-ranging, as some see him becoming a real power threat, while others see a line-drive swing and more of a leadoff profile. His second-half breakthrough came with a far more aggressive approach at the plate, and he'll need to find some balance there. He's a poor defensive outfielder who needs his speed to make up for poor jumps and routes, which have so far limited him to a corner. Perfect World Projection: If the power comes as some scouts believe, Puello could become a monster. Without it, he's a unique talent as a corner outfielder with a center fielder's skill set. Path to the Big Leagues: Puello will make his Florida State League debut just days after his 20th birthday. Even if he begins to drive more balls, it won't show up in the stat sheet until he gets to Double-A. ETA: 2013.
