The Royals clinched the 11-12-year-old Little League baseball title at Idle Hour Park last week, while the Mets locked up a championship in the 9-10-year-old league on Monday.
The Royals (7-2) have a game left on the schedule, but have already run away with the league title, holding a three-and-a-half-game lead over the Reds, and a four-game advantage over the Nationals.
The Mets (6-3) clinched first place with a 1-0 win over the Orioles, who sit one game back. The Marlins round out the 9-10-year-old league three-and-a-half games behind the Mets.
