Cameron Payne felt the Philadelphia 76ers found "the right juice" against the Milwaukee Bucks on Thursday, but it wasn't enough as Giannis Antetokounmpo led the championship hopefuls to victory.

Antetokounmpo scored 32 points and added 11 rebounds as the Bucks rallied for a 114-105 win over the 76ers, who had led 83-80 at the start of the fourth quarter.

However, the Bucks inched ahead of their short-handed visitors with eight minutes on the clock, then AJ Green added three free-throws and a 3-pointer to open up a commanding lead.

The Sixers have now lost 13 of 20 games without reigning NBA MVP Joel Embiid, who hopes to return before the end of the season after undergoing surgery to repair the lateral meniscus in his left knee.

However, both Payne and head coach Nick Nurse sought to take the positives from Thursday's performance. 

"I feel like we had the right juice today. We had fun and it showed on the court," Payne said after finishing with 13 points in support of Tyrese Maxey, who had 30. 

Nurse echoed that view, saying: "I think the effort was really good. We were doing a lot of things we wanted to do. We turned them over a bunch in the first half. 

"Probably the difference in the game was that we didn't quite get to as many turnovers in the second. But I thought we did a lot of really good things."

The victory – Milwaukee's third in a row on home turf – improved the Bucks to 43-24, a record which is good enough for second place in the Eastern Conference behind the 52-14 Boston Celtics. 

"They were the instigators throughout the entire first three quarters," Bucks coach Doc Rivers said. "I thought in the fourth quarter it flipped."

Deandre Ayton's dunk with less than one second to play gave the Phoenix Suns a stunning 104-103 victory over the Los Angeles Clippers and a 2-0 lead in the Western Conference Finals. 

Ayton was the Suns' most reliable player throughout a back-and-forth affair and came up huge in the end, soaring to catch an inbounds pass from Jae Crowder over the rim and slam it home for the final margin. 

After the last in a series of lengthy video reviews in the final two minutes, the officials put 0.7 seconds on the clock for the Clippers, but Paul George could not get off a shot before the buzzer expired. 

With the Suns missing team leader Chris Paul due to COVID-19 protocols and their star Devin Booker having a difficult night, it was Ayton who came up huge Tuesday. 

The big man scored 12 points in the first quarter on the way to a 24-point night on 12-of-15 shooting in addition to grabbing a game-high 14 rebounds. 

On a night that saw Booker make only five of 16 shots from the field and turn the ball over seven times, Paul's replacement Cam Payne was a huge factor for Phoenix. 

Payne, whose previous career playoff scoring high was 19 points, scored 29 in 37 minutes on a memorable night in Phoenix. 

The Clippers were also missing a star as Kawhi Leonard sat out a fourth consecutive game with a knee injury, and George could not lift Los Angeles to victory by himself. 

The veteran led the Clippers with 26 points but made just 10 of 23 shots and missed two critical free throws in the closing seconds to give the Suns a chance to win it. 

The series shifts to Los Angeles on Thursday with the Clippers looking to bounce back at home.
