The San Antonio Spurs are just one win away from clinching basketball's NBA title, after trouncing the two-time defending champions the Miami Heat 107-86 in game four in Miami.
The one-sided win gives the Spurs a 3-1 lead in the best of seven series.
It puts them in position to claim a fifth championship in 15 years when the series shifts to San Antonio for game five on Monday.
Kawhi Leonard led San Antonio's scoring with 20 points and Tony Parker made 19, with the Spurs leading 55-36 at half-time.
LeBron James, a shadow of himself during the first half, came alive in the third quarter in scoring 19 of Miami's 21 points but it was not enough to slow the Spurs.
James led the Heat with 28 points, with Chris Bosh next-highest with 12.
