The Kansas City Royals have earned their first World Series title in 30 years, staging a dramatic Game 5 comeback to beat the New York Mets 7-2.

They took home the series four games to one.

The final game featured a stunning extra-innings turnaround. It started as a pitchers' duel: the Mets' Matt Harvey against Kansas City's Edinson Volquez.

Beating the Mets 5-3, the Kansas City Royals came from behind in the eighth inning, placing themselves one win closer to a World Series title. A Royals rally and a fatal error by second baseman Daniel Murphy leaves Kansas City one game away from their first championship title in 30 years.
