The Phoenix Suns outclassed defending champions the Milwaukee Bucks on Thursday to win 131-107 and stretch their NBA-best record to 45-10.

In a rematch of last season's Finals, won by the Bucks, Phoenix pulled clear in the second half after a competitive opening two quarters in Arizona.

Deandre Ayton top-scored for the Suns with 27 points, finishing on 12-of-14 shooting from the field, while Chris Paul enjoyed a special game: his 17 points and 19 assists brought about his 500th career double-double, a tally only previously reached by three guards in the league's history.

"I'm grateful that I still get a chance to play," he said. "Not just play, but I feel like I play at a high level every night. It's cool."

It was a 15th win from 16 games for the Suns and reinforced their championship credentials against the team who came from 2-0 down to win last year's Finals series 4-2.

"They're the defending champs. We still hurt," said coach Monty Williams. "But from a confidence standpoint, for sure, it was a big game for us. I can admit it now."

The Golden State Warriors, second to the Suns in the West, fell to a second straight defeat for only the third time this season despite a double-double from Stephen Curry.

Julius Randle's 28 points and 16 rebounds, the latter an equal-high for the season, saw the New York Knicks win for the first time in four games in their West Coast trip, Klay Thompson's missed buzzer-beater meaning it finished 116-114.

The Miami Heat remain top of the Eastern Conference, their dominant second-half display seeing them to a 112-97 defeat of the New Orleans Pelicans. Jimmy Butler and Bam Adebayo each scored 29 points for Miami, while Kyle Lowry got his first triple-double of the season.

Doncic hits 50 for first time

The latest star turn in the incredible early career of Luka Doncic helped the Dallas Mavericks beat the Los Angeles Clippers 112-105 in Texas.

The 22-year-old scored a career-best 51 points, 28 of which came in an astonishing first quarter in which he hit seven of his attempted nine three-pointers.

Marcus Morris Sr. top-scored for the Clippers with 21, while Reggie Jackson posted 18, but there was simply no way back from the damage dealt by Doncic.

"Tonight was just Luka," said Clippers coach Tyronn Lue. "That little step-back three, I'll live with that. That's his shot, but if he misses a couple or few of those, then the game is different. But he made them, and that's why he's a great player."

Kuzma triple-double settles clash of busy traders

In a battle of teams at the heart of the trade deadline drama, the Washington Wizards beat the Brooklyn Nets 113-112.

A first career triple-double of 15 points, 13 rebounds and 10 assists for Kyle Kuzma proved pivotal for the Wizards, who added Kristaps Porzingis on a busy Thursday in the week they lost Bradley Beal for the rest of the season to a wrist injury.

The Nets, who sent James Harden to the Philadelphia 76ers in a blockbuster trade involving Ben Simmons, Seth Curry and Andre Drummond, slipped to a 10th loss on the spin despite Kyrie Irving's 31 points.

Elsewhere, Kevin Porter Jr. put up 30 points as the Toronto Raptors beat the Houston Rockets 139-120, while the Memphis Grizzlies took their winning streak to four, Ja Morant scoring 23 points in a 132-107 rout of the struggling Detroit Pistons.
