San Antonio moved to the brink of sealing the top seed in the NBA Western Conference playoffs by beating Dallas 109-100, with Patty Mills scoring 26 points starting in place of Tony Parker.
Making his second start of the season and seventh of his career with Parker nursing a bad back, Mills had 11 points and a pair of steals in the third quarter when the Spurs turned a two-point deficit into an 11-point lead.
The Spurs beat the Mavericks for the ninth straight time in the regular season, a streak that has lasted more than two years.
Kenneth Faried made a turnaround hook shot over Draymond Green with a half-second remaining, and the Denver Nuggets made Golden State wait at least one more game to secure a playoff berth with a stunning 100-99 win over the Warriors.
Stephen Curry's floater over Faried put the Warriors up 99-98 with 4.7 seconds to play, sending the announced sellout crowd of 19,596 roaring to their feet. Faried quieted fans moments later, backing down Green for the winning shot.
