Bryce Harper, OF, Washington Nationals, Grade A: Hit .318/.423/.554 with 14 homer and 19 steals in Low-A, then .256/.329/.395 with seven steals in Double-A, at age 18. Still the best overall prospect in baseball with this very impressive debut.
2) Domonic Brown, OF, Philadelphia Phillies, Grade A: Hit .261/.391/.370 with 12 steals in Triple-A, then.245/.333/.394 in 184 major league at-bats. He'll be fine, he just needs to play.
3) Jesus Montero, C, New York Yankees, Grade A: Hit .288/.348/.467 in Triple-A, then .328/.406/.590 for the Yankees in September. He's clearly ready for a major league job offensively, and should be the next great Yankee slugger.
4) Mike Trout, OF, Los Angeles Angels, Grade A: Hit .326/.414/.544 with 33 steals in Double-A, then .220/.281/.390 in 123 major league at-bats. He was rushed a bit at age 20, but all the markers of stardom are still here.
5) Mike Moustakas, 3B, Kansas City Royals, Grade A: Hit .287/.347/.498 in Triple-A, then .263/.309/.367 in 338 major league at-bats. The power will come eventually.
22) Wilmer Flores, SS, New York Mets, Grade B+: Hit .269/.309/.380 with nine homers in 516 at-bats in High-A. Performance OK but not terrific, however he's still just 19 years old.
