The Cavs took control of the series, but they nearly let it slip through their fingers due to a rare lapse in defensive effort. It's a lesson learned.

Donovan Mitchell scored 17 of his 30 points in the fourth quarter and Darius Garland contributed 21 points and nine assists as the Cleveland Cavaliers held on for a 121-112 win over the visiting Miami Heat on Wednesday in Game 2 of their Eastern Conference first-round series.
