Verstappen now leads Perez, his closest rival, by a mighty 138 points with nine races remaining.
Red Bull lead Mercedes by 285 points with Aston Martin 40 points further back and 14 ahead of Ferrari.
Verstappen came in a lap later but resumed well down the field and set about closing the gap.
The safety car was deployed from lap 16 to 21 when U.S. rookie Logan Sargeant crashed his Williams at turn eight.
Verstappen appeared to be cruising to victory until the final deluge and the halt after Alfa Romeo's Guanyu Zhou crashed heavily, without injury.
