Yonder Alonso is #3 behind Buster Posey and Andrew Brackman. Seriously, Andrew Brackman #2? That is funny. Brackman posted a 5.56 ERA and walked 25 batters in 34 innings. Posey posted a .797 OPS compared to Alonso's .929 OPS. Todd Frazier was #7.
A little summary on what Baseball America had to say about Alonso and Frazier:
Most offensive upside of any prospect in Hawaii. Strong, short to the ball, and very selective. Could move quickly. Hits to all parts of the field. Good plate coverage. Biggest adjustment will be facing lefties with good breaking balls.
Fast hands compensate for a high setup. Held his own at shortstop. Has plus raw power and led the league in slugging. The ball jumps off his bat. Will be a frontline hitter. Played all four positions (1B, 3B, SS, LF) well.
