Kevin Durant had 49 points, 17 rebounds and 10 assists in one of the most spectacular performances in postseason history, sending the Brooklyn Nets back into the lead in the Eastern Conference semifinals with a 114-108 victory over the Milwaukee Bucks in Game 5 on Tuesday night.

With James Harden returning but delivering little offense and Kyrie Irving out, Durant played all 48 minutes and shot 16 for 23 from the field. He scored 20 points in the fourth quarter, perhaps the biggest shot a 3-pointer with 50 seconds left and the Nets protecting a one-point lead.

The two-time NBA Finals MVP became the first player in NBA history to have at least 45 points, 15 rebounds and 10 assists in a playoff game.

Harden played for the first time since leaving 43 seconds into the series opener with right hamstring tightness. He shot just 1 for 10 and missed all eight 3-pointers, but had eight assists and six rebounds while playing 46 minutes.

Jeff Green made seven 3-pointers and scored 27 points for the Nets, who fell into a 17-point hole in this one after two losses in Milwaukee before Durant carried them back. Blake Griffin added 17 points.

Game 6 is Thursday in Milwaukee, where the Bucks are 4-0 against the Nets this season.

Giannis Antetokounmpo had 34 points and 12 rebounds, while Khris Middleton added 25 points.

The Bucks had all the momentum after winning the two games in Milwaukee, with Irving spraining his ankle in the second quarter of Game 4. It appeared Durant would be the only one of the three superstars to play Tuesday — which given the way he played, may have been enough anyway.

The Nets originally ruled Harden out on Monday, then upgraded him Tuesday first to doubtful and then questionable. He worked out before the game and seemed to be moving well, jogging off the court into the tunnel after his warmup before being cleared to play.

But he didn’t appear to have full strength in his leg, leaving jumpers short and rarely beating anyone on the dribble.

Durant made sure it didn’t matter.

The Nets were 4 for 20 in the first quarter, 2 for 13 on 3-pointers, and Middleton’s three-point play with 33 seconds left gave Milwaukee a 29-1 lead after one.

Durant’s basket got it down to 42-33 before Antetokounmpo rattled in a 3-pointer and follow with two more baskets to push the lead to 16, which is where it still was when the Bucks took a 59-43 lead to the half.

The Bucks still led by 16 midway through the third quarter, answering every time the Nets seemed to have any momentum. But Durant then got hot and never really cooled off.

He made all four shots and scored 11 points in the final 6:18 of the third as the Nets pulled to 87-81 on his three-point play with 31 seconds left.

Durant kept right on going to open the fourth, with his 3-pointer with 8:36 to play making it 94-93, Brooklyn’s first lead since it was 2-0.

Nets: Irving was voted to the All-NBA third team, the first All-NBA selection for the Nets since Jason Kidd was voted to the first team in the 2003-04 season. ...

PLAYER’S CHOICE

Coach Steve Nash said before the game the decision to play would rest with Harden. Harden has never won an NBA title and pushed to get back for this game once it became clear the Nets wouldn’t have Irving.

“So James is driving this,” Nash said. “We have to try to support him the best way we can and be an aide for him to figure this out, but it’s a tricky situation but it’s one that we’re willing to go down with James.”
