MIAMI (AP) -- Kawhi Leonard had 20 points and 14 rebounds, and the San Antonio Spurs dominated the Miami Heat again in a 107-86 victory Thursday night to take a commanding 3-1 lead in the NBA Finals.

Tony Parker added 19 points for the Spurs, who can win their fifth championship with a victory at home in Game 5 on Sunday.

LeBron James had 28 points and eight rebounds for the Heat, but Dwyane Wade was just 3 for 13 for 10 points as the Heat were routed at home for the second straight game.

The Heat would have to become the first team to overcome a 3-1 deficit in the NBA Finals to win their third straight championship.
