Billy Butler spent the bulk of his career with the Kansas City Royals where he has a decent run as their Designated Hitter.  Butler was a horrific fielder (thankfully he played in the American League) but he had some respectable offensive numbers over his career with 1,479 Hits and 147 Home Runs.  He would be named an All Star, a Silver Slugger and the Edgar Martinez Award winner in 2012.

Certainly hampered on this list by his lack of defensive skills, Billy Butler was best used as a Designated Hitter, a role he spent approximately two thirds of his Royals career at.  Focusing on his offensive skills, Butler was a more than capable DH winning the Edgar Martinez Award as the DH of the year in 2012.  Five years in a row (2009-13) he would hit 15 or more Home Runs and he would post two .300 seasons with a decent career Royals Batting Average of .295.
