Louis Williams’ dunk with 29 seconds left lifted the Philadelphia 76ers over the San Antonio Spurs in the inaugural game of the NBA Summer League. Williams, who appeared in 61 games last season for the Sixers, led the way with a game-high 19 points (6-11 FG) in 36 minutes of action.

Bobby Jones (11 points) gave Philadelphia the lead for good at 61-59 when he hit a three-pointer from the left wing with 1:55 left in the game. After an offensive foul by Spurs’ center Jackie Butler, the Sixers iced the game with the final four points.

The Sixers led by as many as 14 points early on, but the Spurs used a 19-12 third quarter to get back in the game. Butler scored five straight during a 6-0 spurt to give the World Champs their biggest lead of the game at 53-48 in the third.

Former UNLV product Louis Amundson chipped in 16 points (4-12 FG) and a game-high 11 rebounds in the win.

“I’m just trying to work hard and play as well as I can,” Amundson, who appeared in 11 NBA games with the Sixers and Jazz last season, said of his goal to get back to the NBA. “I understand that the D-League is different from the NBA, it’s a big step up. I’m just trying to work on my game and work hard, that’s all I can do.”

First-round pick Thaddeus Young displayed some nice moves en route to five points.

“It was great being out there playing,” Young said of his NBA debut. “Much more physical than the college game, but I think I held my own and did alright.”

Three Spurs scored in double-figures led by James White (5-9 FG) and Las Vegas native C.J. Watson (5-11 FG) with 13 points a piece. Butler had 11 points (3-8 FG), five rebounds, six assists and committed eight fouls (five in the first half) in the loss.

The game marked the first of a nine-day, 55-game schedule for the summer league.
