Donovan Mitchell missed his first seven 3-point attempts on Sunday night in the Cleveland Cavaliers' playoff opener against the Miami Heat. It didn't even matter. That's how good Mitchell was attacking the basket early and often.

In the regular season, the Cavs played in 38 clutch games and finished the season with the second-best win percentage in those contests (68.4%). But now, as the stakes rise, the Cavs needed a test like Wednesday night.

CLEVELAND (AP) — Donovan Mitchell scored 30 points, including 17 in the fourth quarter, and the Cleveland Cavaliers held on for a 121-112 victory over the Miami Heat on Wednesday night for a 2-0 lead in their Eastern Conference first-round series.
