CLEVELAND - Kevin Durant made a go-ahead 3-pointer with 45 seconds left and the Golden State Warriors took a 3-0 in the NBA Finals by beating the Cleveland Cavaliers 118-113 on Wednesday night.

Durant scored 31 points and Klay Thompson had 30 for the Warriors, who improved to 15-0 in the postseason and are on the brink of the first undefeated finish in the NBA. Stephen Curry had 26 points, 13 rebounds and six assists.

LeBron James had 39 points, 11 rebounds and nine assists for the Cavaliers, and Kyrie Irving added 38 points. Blown out in the first two games, the Cavaliers were much better in Game 3, but just not good enough to beat a team that could go down as one of the best ever.

Game 4 is Cleveland Friday night.
