Milwaukee Bucks head coach Mike Budenholzer praised Giannis Antetokounmpo for his aggressive mindset after he starred in Game 3 of the NBA Finals.

Antetokounmpo posted 41 points to see the Bucks past the Phoenix Suns 120-100 on Sunday, becoming the first player to score 40-plus points in back-to-back NBA Finals games since LeBron James in 2016.

The win was crucial for the Bucks, who now trail the Suns 2-1, and Budenholzer lauded Antetokounmpo's performance.

"He's just doing whatever it takes to help his team, to help us. He's in an aggressive mindset. He always plays that way," he told a news conference.

"But I thought he played with the pass well. He made some great reads, found guys, played against the zone.

"He just did a little bit of everything. Offensive boards, putbacks. We need a lot from him and that's what he does."

While Antetokounmpo starred, the Bucks also had Jrue Holiday (21), Khris Middleton (18), Brook Lopez (11) and Bobby Portis (11) in double digits for points.

Antetokounmpo also finished with 13 rebounds and six assists and Budenholzer said the star's ability to bring his team-mates into games was crucial.

"I think that's when we are at our best, when Giannis is at his best, it's a little bit of both," he said.

"He's a great playmaker, screener, passer and he does so many great things.

"I think when he's conscious of doing a little bit of everything, he's very capable and that's when he's at his best."

Game 4 of the series is in Milwaukee on Wednesday.
