Cleveland left no doubt on its way to Round 2 — and finished off the most lopsided series in NBA playoff history.

The Cavs closed out Miami with a 55-point rout in Game 4 and outscored their opponent by 122 points in four games

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.
