It's already been a very active season for baseball's top prospects, with some of the top players in the game on the move.
Derek Norris, widely regarded as one of the top offensive catchers in the game, was dealt from Washington to Oakland, along with RHP Brad Peacock, who had one of the finest seasons of any pitcher (15-3, 2.39 ERA) in the minors in 2011, LHP Tom Milone, one of baseball's top young control specialists (155-to-16 K:BB ratio in 2011) and RHP A.J. Cole, one of the Nats top young pitching prospects.
Cincinnati sent a massive haul to San Diego in exchange for starting pitcher Mat Latos, including C Yasmani Grandal, the 12th-overall selection in the 2010 draft, 1B/OF Yonder Alonso, the seventh-overall pick in 2008 and Brad Boxberger, potentially San Diego's closer of the future.
Don't expect the fun to end anytime soon, however, with several teams looking to bolster positions of weakness on their roster before spring training.
As such, let's take a look at the top trade-chip from each team heading into the new year.
