A two-way player and 2004 Little League star who most preferred as a pitcher, righthander Jurickson Profar was signed as an international free agent in 2009. At the time, the teen was blessed with a 94mph heater and a slider that could have matured into a real plus pitch, but the Rangers were determined to make a shortstop out of him, and so far it's paying off. A full season off the mound later and he's showing off every tool in the box, including a ridiculously-advanced batting eye for a teenager. In 430 at-bats in the Sally League, Profar walked more often than he struck out (65 vs 63), an incredibly rare feat among young players.

He also did everything else well, showing on-base proficiency (.390 OBP), baserunning (23/32 steals, 8 triples), and even a little unexpected power: 12 homers, .883 OPS. Heck, even his .955 fielding percentage is acceptable considering he's only recently committed to fielding at all. A real future superstar in the making, it's hard to rate this kid too highly: he looks like nothing less than a switch-hitting Justin Upton right now. He could be scary-good come 2014.
