Ben Simmons made a game-winning tip-in at the buzzer and Joel Embiid scored 34 points and took 12 rebounds as the Philadelphia 76ers outlasted the short-handed San Antonio Spurs 113-111 on Sunday in a wild game in the Alamo City.

Points were at a premium in the overtime, and Rudy Gay's driving layup with 19.1 seconds left tied the game at 111. Embiid's shot with one second remaining bounced off the rim but Simmons leaped high and tipped in the rebound to provide the 76ers their fourth straight win.

Simmons' tip-in was the 76ers' only basket in overtime. Philadelphia remained atop the Eastern Conference standings thanks to the victory.
