Kawhi Leonard had 20 points and 14 rebounds, and the Spurs routed the Heat again, winning 107-86 on Thursday night to open a commanding 3-1 series lead.
The Spurs can win their fifth NBA championship with a victory at home in Game 5 on Sunday and avenge their seven-game loss to Miami last year. They have three chances, and the way they're dominating the Heat, they might need just one.
LeBron James had 28 points and eight rebounds, but Dwyane Wade was just 1-of-10 through three quarters and finished with 10 points.
"They smashed us," James said. "Two straight home games got off to awful starts. They came in and were much better than us in these last two games. It's just that simple."
