LeBron James made a three-pointer with 68 seconds left on Sunday and the Cleveland Cavaliers hung on for a 106-102 series-clinching victory at Indiana.

James finished with 33 points and 10 rebounds as he became the first player under the current playoff format to win 21 straight first-round games. He also set a league record with his 10th career playoff sweep.

It wasn’t easy. After taking a 96-83 lead with 9:29 to go, the Cavs found themselves in a 102-100 deficit with 1:31 left. But James answered with the go-ahead three-pointer and Cleveland sealed the win on James’ free throw with one second left.

Lance Stephenson scored 22 points and Paul George added 15 but missed a three-pointer that could have forced overtime in the closing seconds. It’s the first time the Pacers have lost a series 4-0 in their NBA history.

Kyrie Irving added 28 points for the Cavs, who await the winner of the Bucks-Raptors series.

Indiana got back into the game with a 7-0 run early in the in the fourth, then continued chipping away at the lead until Thaddeus Young tied the score at 100-100 with a short jumper and broke the tie on a tip-in with 1:31 left. But James, whose teams were 51-0 when starting the fourth quarter with double-digit leads in the postseason, made sure the perfect record remained intact.

Cleveland have won seven straight playoff games overall and 11 straight in the first round since James returned to his hometown team. It was another milestone day for James, who moved past Michael Cooper, Magic Johnson and James Worthy on the league’s list of consecutive first-round wins, and past Tim Duncan for most career sweeps, according to Elias Sports Bureau.

James also went 13 off 25 from the field, tying Kobe Bryant for fourth on the career playoff list for field goals. Each have 2,014 baskets. Indiana has lost five straight postseason games and six of its last eight.
