Coming off the bench, Mills had a game high 26 points - his second-best scoring output this campaign - and tied his season high with six three-pointers.

San Antonio set a record by being involved in a fourth-straight overtime game; the NBA record book showed 20 instances of teams playing three overtime games in a row.

The Spurs are 3-1 in their past four games, their best stretch since opening the season 4-1. They are now 10-15.

DeMar DeRozan pulled the Spurs even with a drive and fling - after a foul by Mikal Bridges - down the right side of the lane, but missed the free throw.

The ball went out of bounds on a scramble after the missed free throw.

San Antonio kept the ball after a replay review and ran a play for Mills that came up trumps.

"We've had four overtime games in a row now and we've won three of them and I think there's something positive to be said for that," Mills said.

"Tonight it was the execution. We haven't had the greatest of seasons but we're learning as we go."

Baynes, who only last week returned from a nine-game absence due to injury, came off the bench for the Suns and had 13 points and eight rebounds.

The Boomers centre/forward had a chance to win the game from beyond the arc but his buzzer-beater missed as the Suns lost their third of four and seventh of 10.

Ricky Rubio led Phoenix with 25 points and 13 assists as they dropped to 11-14 on the season.

Pascal Siakam scored 30 points while Marc Gasol set season highs with 17 points and 15 rebounds as Toronto Raptors beat Brooklyn Nets 110-102 to snap a three-game home losing streak.
