Danny Duffy played 12 years in the Majors, all of which have been for the Kansas City Royals.  Duffy has been used primarily as a Starting Pitcher, his highlight being the 2016 season where he went 12-3 with 188 Strikeouts.  He was the Royals’ Opening Day Pitcher in both 2016 & 2017 and prior to that in a relief role he helped KC win the 2015 World Series.

A reliever for his entire career with the Kansas City Royals Kelvin Herrera worked his way through the bullpen and by 2014 he established himself as the seventh inning Pitcher for the team.  Herrera excelled in this role and was gold as a setup man for the team and his contribution to the organizations back-to-back World Series appearances cannot be discounted.  Herrera’s post-season record for Kansas City was 2-0 with a 1.26 ERA and he was a two-time All-Star for the team.  He would later be named the closer and he recorded 57 Saves for KC.

After three seasons playing for the Milwaukee Brewers, Alcides Escobar was traded to the Kansas City Royals, where he would play eight years.  Escobar has collected numerous Hits as five of his seasons with KC have seen him go 150 or more and he has also given them four 20 Stolen Base seasons.  While his hit accumulation has been good (he is one of the few Royals who have over 1,000 Hits for the team) he is certainly penalized on this list for having an abysmal On Base Percentage.  As a Royal, the Venezuelan Shortstop has only had two seasons of .300 OBP and his career OBP for Kansas City is .295.  Throw in a lack of power and there are clearly some deficiencies in his game. 

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.
