The score was tied at 98-98 with 31.9 seconds left in regulation before Curry was denied a layup by a superb block from behind by Kyrie Irving, then LeBron James missed a jump shot for the Cavaliers with only 3.6 seconds remaining.

Curry had a team-high 26 points on 10-of-20 shooting while James weighed in with 44, his most ever in a Finals game, in a losing cause as the Cavaliers were outscored 10-2 in overtime.

Asked how his team had coped with the offensive threat posed by James, who is back in the NBA Finals for a fifth consecutive year, Curry replied: "These guys stick to the game plan. We know what he is about and what he's capable of.

"Our guys guarded him all night and made it tough on him. This is a long series."

James also added eight rebounds and six assists while big center Timofey Mozgov contributed 16 points for Cleveland.
