1) Javier Baez, SS, Grade A: Borderline A-. Has some rough edges with the strike zone and plays a bit recklessly at times, but his bat speed is so good he gets away with an overaggressive approach. Should produce plenty of power and batting average, and I expect the discipline will improve. Even his defense was better than expected. Gary Sheffield comps may prove quite valid.
2) Albert Almora, OF, Grade B+: Solid or better tools in all categories, excellent makeup. Was supposed to have good plate discipline but he only walked twice in 145 plate appearances, which is unacceptably low. However he kept his strikeouts under control and scouts believe he will adjust.
3) Jorge Soler, OF, Grade B+: Highly impressive power/speed combo from the Cuban defector. Main advantage Almora has at this point is a better birthday, but I love Soler. Another Sammy Sosa?
4) Dan Vogelbach, 1B, Grade B: Borderline B+. I'm having the courage of my convictions with this one. This guy is not just a masher, he's got excellent pure hitting skills too, and he's worked hard to get himself into better shape. Could end up as a Prince Fielderish run producer if everything maxes out.
5) Arodys Vizcaino, RHP, Grade B-: Rating is cautious until we see how rapidly he bounces back from Tommy John surgery.
6) Brett Jackson, OF, Grade B-: Tough ranking. All the tools are here, love the power/speed combination and he'll take a walk, but his strikeout problem could destroy his career if he doesn't make some adjustments.
7) Dillon Maples, RHP, Grade B-: Could develop into a number two starter due to promising fastball/curveball combination, but we need more data from higher levels to see if his command improves and if his mechanics (which some scouts don't like) become an issue.
8) Christian Villanueva, 3B, Grade B-: Nice pickup from the Rangers. Outstanding glove at third base, gap power, superior makeup. Needs to tighten up the strike zone but I think he can.
9) Matt Szczur, OF, Grade B-: I don't like him as much as some people do, but the tools are obvious. At worst he should be a good reserve outfielder with speed and defense, but it is still an open question if he hits enough to play regularly.
10) Pierce Johnson, RHP, Grade B-: Solid all-around, good fastball and strong curve, throws strikes, main worry is history of forearm troubles. Mid-rotation starter if his arm holds up.
11) Gioskar Amaya, 2B, Grade B-: I think he will take a huge step forward in 2013. Defense at second base is better than it was at shortstop. He's got pop, can steal bases, and has a good swing.
12) Duane Underwood, RHP, Grade B-: Borderline C+: One of my favorite players from the 2012 draft. He's erratic but was also one of the youngest guys in the entire draft class. When right, he's got upper-90s velocity and promising secondary pitches. Needs more consistency in all respects, as his velocity varies and his command is problematic.
13) Josh Vitters, 3B, Grade C+: Borderline B-. Maybe I'm underestimating him and this is just psychological prospect fatigue. I can see a B- case and ranking him as high as 11th. But after watching him many times over the years, I remain unimpressed with the glove, and if he ends up at first base the pressure on the bat will grow all the stronger.
14) Junior Lake, SS, Grade C+: Borderline B-: As with Vitters, I can see ranking him ahead of Underwood due to his proximity to the majors. Lake's tools are tremendous but he is still a very raw and frustrating player. He could turn into Nelson Cruz, or Angel Berroa.
15) Jeimer Candelario, 3B, Grade C+: Although his power production sagged in the Northwest League, he's young for the level and scouts still think he'll hit for average and power as he moves up. Poor defense will likely result in a positional switch at some point. Could be much higher next year.
16) Juan Carlos Paniagua, RHP, Grade C+: Scouting reports about his power arm are certainly intriguing, but let's see how it pans out. Could be much higher once we get some objective data.
17) Paul Blackburn, RHP, Grade C+: Doesn't have Underwood or Paniagua's upside, but he's quite polished and has strong pitchability and makeup.
18) Marco Hernandez, SS, Grade C+: Defense gets strong reviews and he's got a chance to hit, too. Hernandez/Candelario/Amaya is a hell of an infield for Low-A in '13.
19) Arismendy Alcantara, SS, Grade C+: In the middle of a strong age 20 breakout season (.302/.339/.447 with 25 steals) in High-A when he got injured, but healthy now and back in action in the Dominican Winter League.
20) Barret Loux, RHP, Grade C+: Could be a useful fourth starter, and soon, assuming that he stays healthy. Medical record is long, but he hasn't had issues since getting into pro ball.
