Myers, who also earned Minor League Player of the Year honors from Baseball America and USA Today, hit .314 with 37 home runs and 109 RBIs between Double-A Northwest Arkansas and Triple-A Omaha this season.
Myers is the third Royals player to win the Spink Award, joining Johnny Damon in 1995 and Alex Gordon in 2006. The 21-year-old Myers is just the third player to win all three Minor League Player of the Year Awards in a season, along with Andruw Jones (1996) and Josh Beckett (2001).
"I am honored to win this prestigious award from Topps and Minor League Baseball," Myers said in a statement. "To join a list with great players such as Johnny Damon and Alex Gordon is extremely humbling for me."
A third-round pick of Kansas City in the 2009 Draft, Myers is ranked the third-best prospect in all of baseball, according to MLB.com's Prospect Watch. His 37 homers in 2012 trailed only Darin Ruf, who hit 38 regular-season home runs for Double-A Reading, a Philadelphia Phillies affiliate, among all Minor Leaguers. Myers' 333 total bases led the Minor Leagues, while his RBI totals ranked fourth.
