Stephen Curry and Draymond Green capped triple-double performances by combining on the game-clinching hoop in overtime as the Golden State Warriors completed a sweep of the host Portland Trail Blazers in the Western Conference finals with a 119-117 victory.

The win vaults the Warriors into their fifth consecutive NBA Finals. They will await the eastern conference winner between Milwaukee and Toronto, with either the Bucks or Raptors holding the home-court advantage in the best-of-seven series.

Golden State, the two-time defending champion, join the Boston Celtics (1957-66) as the only teams ever to reach five consecutive NBA Finals.

Playing without Andre Iguodala, Kevin Durant and DeMarcus Cousins, the Warriors led just 116-115 before Curry spotted Green open for a three-pointer that pushed the Golden State lead to four with just 39.6 seconds remaining in OT.
