1. Ned Yost , Kansas City Royals
After a slight improvement form 2011 to 2012, Yost led the Royals to an 86-76 season in 2013 behind a solid core group of young players. If the Royals flop, and players like Eric Hosmer , Alex Gordon  and Salvador Perez  take a step backwards instead of forward, Yost might find himself unemployed. The rebuilding years in Kansas City are over, they’re expected to contend, and if they don’t someone’s got to go.
