David Cone would become known (right or wrong) as a “gun for hire”, a Pitcher who could get you over the hump.  While he was often a Cy Young contender the only time he did win the award was in 1994…when he was a member of the Kansas City Royals.

Joakim Soria joined the Kansas City organization as a Rule 5 selection from the San Diego Padres in late 2006, a diamond-in-the-rough find who would immediately transform into one of the most dominant closers in the game. Making his debut in 2007, the right-hander from Monclova quickly earned the nickname "The Mexicutioner" for his cold-blooded efficiency in the ninth inning.

After saving 17 games as a rookie, he evolved into an elite force between 2008 and 2010. During this stretch, he demonstrated a specialized ability to lock down games with a microscopic 1.84 ERA and a 1.005 WHIP. He showed the organization he was a foundational star by earning two All-Star selections and delivering a historic 2010 campaign. That summer, he recorded a career-high 43 saves, finished second in the league in Win Probability Added (WPA), and placed tenth in the AL Cy Young voting, a rare feat for a reliever on a non-contending team.

The heart of his first tenure was defined by elite durability until a torn elbow ligament required Tommy John surgery, which forced him to miss the entire 2012 season. This injury led to a difficult transition; after five dominant years, the Royals chose not to re-sign him, allowing him to test free agency. However, Soria’s story in Kansas City reached a natural second act when he returned to the club in 2016. During this second run, he pivoted into a veteran setup role, providing the steady-state production needed to bridge the gap for a team coming off a World Series title. While his velocity had dipped slightly, his veteran-like poise remained a tactical asset for the bullpen.

Soria was traded to the Chicago White Sox in early 2018 and had 162 saves for Kansas City.

Eric Hosmer joined the Kansas City organization as the third overall selection in the 2008 draft, a high-ceiling prospect from Florida who would become the face of the Royals' resurgence. After a rapid ascent through the minors, he debuted in May 2011 and immediately secured the starting first base job.

In 2011, he demonstrated a specialized ability to handle the bright lights of the American League, batting .293 and finishing third in the Rookie of the Year voting. He showed the organization that he was a foundational winner during the 2014 and 2015 postseason runs, delivering veteran-like poise and a series of signature moments, none more famous than his "mad dash" home to tie Game 5 of the 2015 World Series. This period of rapid growth served as the essential lead-in to his most productive years, proving his worth as a steady-state run driver for a championship-caliber roster.

In 2016, he earned his first All-Star selection and was named the All-Star Game MVP, signaling his arrival as an elite presence in the sport. He followed this with a historic 2017 season, recording a career-high .318 batting average and earning his lone Silver Slugger Award. He showed the organization that he was a foundational star by belting 25 home runs and driving in 94 runs, providing the offensive muscle for a team in transition. While he secured four Gold Glove Awards (2013–2015, 2017) through a reputation for picking low throws and elite scooping, advanced metrics like defensive bWAR and Total Zone Runs remained consistently critical of his overall range and positioning.

Following the 2017 season, Hosmer signed an eight-year contract with the San Diego Padres.  With Kansas City, he had 1,132 hits, 127 home runs, and the 2015 World Series title.

Kevin Seitzer’s best season of his Major League Baseball career was in his rookie season where in 1987 he was the runner-up for the Rookie of the Year and was the co-leader in Hits.  Seitzer put up what would be career highs in Home Runs (15) and bWAR (5.8) while also boasting a .323 Batting Average and a trip to the All Star Game.  Seitzer never duplicated that year, but he still would put up three more 165 Hit seasons and would have a .294 career Batting Average over his six years in Kansas City.
