SAN ANTONIO — Marco Belinelli had 20 points to lead eight San Antonio players in double figures, and the Spurs worked through a lethargic start to beat the Detroit Pistons 120-110 on Wednesday night.

Kawhi Leonard had 15 points in his return from a 14-game absence due to a broken finger. Manu Ginobili scored 16 points, Tim Duncan and Tiago Splitter had 13 apiece, Boris Diaw added 12, Patty Mills 11 and Cory Joseph 10.

Josh Smith scored 24 points for Detroit, which has lost three straight. Will Bynum added 18 points, Rodney Stuckey 17 and Andre Drummond had 16 points and 17 rebounds.

San Antonio (41-16) got off to a sloppy start despite having two practices during a five-day break following its annual Rodeo Road Trip that lasted nearly a month.
