Lorenzo Cain played for Kansas City for seven seasons and he was arguably the team’s spark plug for much of that time.

In the mid-1970’s it would be hard to dispute that John Mayberry was one of the biggest reasons to catch a Royals Game.  On a team that did not have a lot of power hitters, it was Mayberry who would be the one to most likely go deep. 

Mike Sweeney is one of the all-time good guys of the Kansas City Royals in terms of dugout presence, community involvement and just being a quality human being.  More importantly (for this list anyway) he was a pretty solid player.

Zack Greinke overcame a lot of personal adversity on his way from a high First Round pick to Cy Young Award winner.  Greinke suffered from severe depression and anxiety and was almost out of Baseball but he persevered to become the ace that pundits knew he could always be.
