Kawhi Leonard scored 36 points as the Toronto Raptors beat defending champions the Golden State Warriors 105-92, leaving them one win away from their first NBA championship.
A sensational second half from the Raptors gives them a 3-1 series lead.
The only team to overcome the same deficit in the Finals were the Cleveland Cavaliers, who beat the Warriors in 2016.
