Giannis Antetokounmpo insisted "a win is a win" after the Milwaukee Bucks escaped with an 86-83 victory against the Brooklyn Nets, despite blowing a big advantage in Game 3.

The Bucks had their backs against the wall after falling into a 2-0 hole against the second-seeded Nets in the Eastern Conference semi-finals but responded on home court in Milwaukee.

Milwaukee surrendered a 21-point lead at home to the Nets before Jrue Holiday put the Bucks ahead for good with 11.4 seconds remaining on Thursday.

The Bucks were forced to dig deep during the closing stages, however two-time MVP Antetokounmpo did not dwell on the manner of the win as Milwaukee cut Brooklyn's lead to 2-1 in the NBA playoffs.

"At the end of the day, a win is a win," said Antetokounmpo, who posted 33 points and 14 rebounds.

"It doesn't matter if you win by 30. It doesn't matter if you win by one.

"You can go back home and celebrate the ‘W.' "

Khris Middleton top-scored with 35 points and 15 rebounds as Kevin Durant's buzzer-beating three-point attempt for the Nets bounced off the rim.

The Bucks are the only NBA team in the last 15 years to have two players (Antetokounmpo and Middleton) score 15-plus points in a quarter with no other team-mates posting a point (regular season or postseason), according to Stats Perform.

Antetokounmpo and Middleton combined for 68 points and 29 rebounds. Per Stats Perform, they are the first duo to combine for those numbers in a playoff game since Shaquille O'Neal and Kobe Bryant in 2001.

"We ran a lot of pick-and-roll, the first two games, in Brooklyn. I was able to get my spots, just wasn't making the shot, making the right pass or the right read," Middleton said.

"Tonight, I just tried to make the right read and make those shots. I can see what they are giving, just trying to take advantage of that."

On Milwaukee's defense, Holiday added: "I think part of it is playing desperate, knowing the situation, knowing what this game means to us and what it means to be home.

"And then the other part of it is the performance we had the first two games, showing that's not the type of defense we play. That was really out of character."
