The top-seeded Cavs swept the Miami Heat out of the NBA playoffs Monday night, punctuating their first-round series win with a record-setting 138-83 Game 4 rout. It’s the largest point differential in Cavaliers playoff history. It’s also just the second time in the Erik Spoelstra era that Miami has been swept — and third time ever.

The top-seeded Cleveland Cavaliers and eighth-seeded Miami Heat play Game 4 of an Eastern Conference best-of-7, first-round playoff series Monday.
