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

The Cleveland Cavaliers, started their postseason journey against the Miami Heat and were dominant, completing a series sweep on Monday with a 138-83 victory in Miami in Game 4. That came on the heels of another blowout, a 124-87 win in Game 3 on Saturday. Games 3 and 4 marked the two worst playoff losses in Miami franchise history.

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.
