Ten years ago, the Kansas City Royals made history: After falling to the Giants in a seven-game classic, the Royals returned to the World Series the next year and gave the people of Kansas City its second championship. Led by World Series MVP Salvador Perez and a roster of homegrown stars, the Royals took down the New York Mets in five games.

To celebrate that World Series championship, MLB’s Home Run Derby X – a fast-paced, co-ed, three-on-three version of the classic derby – is headed to Kansas City’s Kauffman Stadium on Sept. 13 with some of the most beloved players in team history joining in. Team legends and 2015 champs Eric Hosmer, Mike Moustakas, Lorenzo Cain, Alex Gordon and Ben Zobrist will all be participating in hopes of mashing dingers and earning a spot in this year’s finals in Salt Lake City.

To get there, they’ll need to beat the same teams they had to in the 2015 postseason: Daniel Murphy and Michael Cuddyer will be joining to represent the New York Mets, while the Toronto Blue Jays’ roster will be announced soon.

The MLB stars will be joined by some of the best players in women’s baseball and softball with reigning Athletes Unlimited Softball MVP Amanda Lorenz and four-time Women’s College World Series champion Tiare Jennings among the women who will be joining to bash home runs.
