OAKLAND, Calif. — The Toronto Raptors had more length, more depth and more athleticism than anyone imagined when the N.B.A. finals began.

The Raptors used all of that — as well as their far superior health — to close down Oracle Arena and close out the N.B.A.’s two-time reigning champions Thursday night with a 114-110 Game 6 victory over the Golden State Warriors.

The Warriors were presumed to possess the emotional advantage coming in, playing their final game at Oracle and dedicating the evening to their superstar forward Kevin Durant, who was on the other side of the country after undergoing major surgery Wednesday. But Toronto just had too much — especially after Golden State lost the All-Star guard Klay Thompson for the entire fourth quarter after a bad landing on a drive to the basket. The Warriors later announced that Thompson had torn the anterior cruciate ligament in his left knee.

Three Raptors, remarkably, outscored or matched Kawhi Leonard in the clincher: Kyle Lowry delivered 11 of his 26 points in the game’s first two-plus minutes. Pascal Siakam added 26 points and 10 rebounds of his own. And the undrafted Fred VanVleet made five of Toronto’s 13 3-pointers to finish with 22 points — 12 of which came in the fourth quarter.
