For every top prospect who had a great year, the Bryce Harpers, Mike Trouts and Matt Moores of the world, there were even more players who came into the season with grand expectations only to suffer gigantic letdowns.
Leading this bandwagon were a couple of very high profile Kansas City prospects, OF Wil Myers and LHP Mike Montgomery. Myers, who enjoyed one of the finest breakout seasons ever produced by a player as young as he was, stumbled out of the gate and ended the 2011 campaign with fewer home runs and RBI, and took a 60-point hit to his batting average. His .254/.353/.393 line was not exactly what the Royals expected from the 10-ranked prospect in the minor leagues, according to Baseball America.
Montgomery's failure was more epic...and you'll read about it in a few slides.
Myers and Montgomery weren't alone in their sorrow. In fact, their fate was shared by some of the top prospects from the Cubs', Rockies' and Twins' systems. Only one player from each organization made this list and while the reasons surrounding their struggles can be argued away in some cases (too young, too inexperienced, etc.) everyone on this list didn't live up to expectations this season.
