Then Paul George stole the show.
George's clutch shot capped a wild finish that included another memorable moment in the rivalry between Westbrook and Embiid. Westbrook absorbed a hard foul from Embiid on a break with 1:46 left, landing out of bounds under the basket.
Westbrook then got up and rushed toward Embiid before he was restrained by his teammates.
''I don't think he just landed on me,'' Westbrook said. ''He had a little extra to it, you know what I'm saying? But it's ok.''
Embiid had a different opinion of the play.
''I think I was going for the block and I think he lost the ball, but I was already in the air,'' Embiid said. ''I don't know what, why he was mad. I have no idea. But he's always in his feelings, so I have no idea.''
Westbrook and Embiid have had a couple chilly exchanges over the past couple years. Asked if he was ''cool'' with Embiid, Westbrook used an expletive before saying ''No.''
Westbrook fouled out with 14.9 seconds remaining after he got Embiid while shooting a 3-pointer. Embiid made all three foul shots, tying it at 113, and Jimmy Butler's driving layup put Philadelphia in front with 6.9 seconds to go.
But George drained a 3 while being fouled by Butler and made the foul shot.
''That's PG,'' Westbrook said. ''You don't get too excited anymore about those I mean they happen so many times. PG's doing what PG does and we just got to see it and get a win.''
Philadelphia had one last chance, but Butler missed a 3-point attempt in the final seconds.
The 76ers have lost 19 in a row to the Thunder. That streak that was on Embiid's mind when he decided to play after he was a game-time decision because of back tightness.
''The Sixers haven't won against them in like 10, 11 years,'' Embiid said. ''That's just ridiculous.''
George finished with 31 points, six rebounds, five assists and three steals. Westbrook had 21 points, 10 rebounds and six assists for Oklahoma City, and reserve Dennis Schroder also scored 21 points.
The Thunder had dropped five of six, including a 138-128 overtime loss against the Los Angeles Lakers on Thursday night.
Oklahoma City led by as many as 16 points in the first quarter, but Philadelphia rallied in the second and trailed 59-56 at the break.
BOUNCE BACK GAME
The Thunder were glad to leave Philadelphia with the win.
''We lost the last two games, so it was pretty tough,'' center Steven Adams said. ''It was just good. It's obviously good to get a win under our belt, just against this team, obviously they had a lot of really good sets.''
