The San Antonio Spurs did not let the Golden State Warriors score for more than six minutes. By then the game was basically over.

Stephon Castle scored 32 points in three quarters and the Spurs opened with an 18-0 run on the way to a 123-85 NBA Cup rout Friday night in San Antonio.

It was the Spurs' 11th straight win.

A historic start

The 18-0 burst was San Antonio's largest run to open a game in the play-by-play era. Castle hit two early 3-pointers off passes from Victor Wembanyama. Wembanyama capped the run with a reverse dunk off a lob from Castle.

The Spurs led 38-14 after the first quarter and 63-33 at halftime.

Castle's big night

Castle made 12 of his 18 shots, including 5 of 8 from 3-point range. He added six assists and five rebounds in just 25 minutes and sat out the fourth quarter.

It was his best scoring night of the season. Several of his baskets were lobs from Wembanyama, who had 12 points, 12 rebounds and six assists in 20 minutes.

Keldon Johnson scored 18 off the bench. Harrison Barnes added 11.

Golden State misses Curry

The Warriors were without Stephen Curry, who is out at least two weeks with an oblique tear.

Golden State shot 33% from the field. Rookie Yaxel Lendeborg, who had been carrying the scoring load, went 1 of 13 and finished with three points.

LJ Cryer led the Warriors with 20 points off the bench on six 3-pointers.
