"Overall we made a lot of mental errors," Spurs coach Gregg Popovich said. "Especially on that last play on the free throw line when Johnson went all the way down the court and he wasn't picked up. That cost us the game."
Johnson's 3 seemed to stun the Spurs even more so than the fans.
"I think we were kind of surprised that Manu missed that last free throw, but they made a great play," Parker said. "Wesley made a big 3."
San Antonio went 0 for 10 in overtime, its only points in the extra period coming when Parker made 1 of 2 free throws.
"I think they missed some shots they normally make, so defensively we did some things great that worked great for us," Phoenix coach Lindsey Hunter said.
The teams combined to go 0 for 14 to open overtime. Marcin Gortat's tip follow was the first basket of overtime, giving Phoenix a 102-101 lead with 1:07 left.
