'Absolutely unreal': NBA world blown away by wild Finals ending

The Milwaukee Bucks have squared the NBA Finals at 2-2 with a 109-103 victory over Phoenix in game four, thanks to an impressive fourth-quarter fightback.

Khris Middleton and Devin Booker each had 40-point games for the Bucks and Suns respectively, but it was an absolutely monumental blocked shot by Giannis Antetokounmpo in the final minutes which swung the game.

The series will head back to Phoenix after Milwaukee held serve at home for the last two games, with the Bucks hoping to capitalise on Antetokounmpo's dominant three-game stretch.

The Bucks lead by two points with just over a minute to play when Booker was able to lob a pass to the rim for DeAndre Ayton.

But the two-time MVP and former defensive player of the year was having none of it, somehow turning and elevating to reject the shot, with the Bucks able to go the other way and extend their lead to four.

Phoenix had been in control for much of the game until Booker found himself in foul trouble late in the piece.

He sat for a key stretch of the fourth quarter with five fouls, before controversy erupted with just under five minutes to play after the referees inexplicably chose not to award him his sixth and disqualifying foul, despite clearly wrapping up Bucks guard Jrue Holiday as he attempted a layup in transition.

Between that play, Booker's scorching shooting through the first three quarters, and Antetokounmpo's game-changing block, NBA fans were going absolutely wild on social media.

Game 5 is Saturday night in Phoenix.

"This is a tough one but we've got to bounce back," Paul said. "That's why we fought all season to get home court."

Middleton is an All-Star with unwavering confidence in his shot, always believing that matter how poorly he starts that he can turn things around.

He may have turned around the course of these NBA Finals.

"We know he's going to take big shots, we know he's going to make big shots and tonight he was incredible," Antetokounmpo said.

Phoenix led by two with 2 1/2 minutes left before Middleton made the next two baskets to give Milwaukee a 101-99 edge with 1:28 to play.

It appeared the Suns would tie it with a lob pass to centre Deandre Ayton but Antetokounmpo swooped in to block it, flexing his muscles to the crowd behind the basket as the Bucks broke the other way on the fast break.

Middleton missed a couple of jumpers but Paul lost the ball after the second one when he slipped and fell down while dribbling. That sent Middleton off for a layup and he followed with four free throws to make it 107-101.

Brook Lopez had 14 points for the Bucks and Jrue Holiday added 13 points, seven rebounds and seven assists. He shot only 4 for 20, but his defence helped knock Paul off his game.

Before Middleton's run, it appeared it was going to be Booker's night. He bounced back in a big way from a 3-for-14 night in Game 3 with his third 40-point game of this postseason.

But he had to spend portions of the third and fourth quarters on the bench after picking up fouls and his teammates couldn't handle things without him.
