The San Antonio Spurs defeated the Oklahoma City Thunder 103-82 in Game 4 on Sunday night to even the Western Conference Finals at 2-2.

Victor Wembanyama finished with 33 points and eight rebounds in the win, and also hit a 40-foot buzzer-beater to end the first half.

"I feel like with who we are, we need to start games like this," Wembanyama said. "I was just thinking shoot to score. I wasn't messing around."

Wembanyama also set a franchise record for most points in a player's first postseason appearance with 324 points, beating Stephen Jackson's previous record of 307 points.

De'Aaron Fox said that Gregg Popovich addressed the Spurs following their Game 3 loss on Friday night.

"Every team gets blown out, but just mentality-wise, I think that was one of the worst games we had probably of the season," Fox said. "Then, Pop came in after the game. He saw it, we all saw it. We all felt it. Coming into this game, we wanted to make sure that mentality was out the door. Even if we lost this game, as long as we came in with the right mentality and played the right way, we could be OK with losing the game. The way that we lost [Game 3] I think hurt more than losing the game and that was pretty much for everybody in the locker room."

Shai Gilgeous-Alexander scored just 19 points on 6-of-15 shooting in the loss. The Thunder also finished 1-of-11 from three in the first half.

Stephon Castle credited the Spurs' approach to defense with the win.

"We really paid attention to detail a lot better than Game 3," Castle said. "Watching the film, we gave them a lot of straight-line drives and just not rotating how we practiced. [Hitting first] just feeds energy throughout the team, especially defensively being the point of attack."

Game 5 is on Tuesday in Oklahoma City.
