Steve Kerr feels Stephen Curry is playing the best basketball of his career after his impressive 57-point outing in the Golden State Warriors' defeat to the Dallas Mavericks.

Curry joined Wilt Chamberlain as the only Warriors players to post multiple 55-point games in a campaign with a season-high 11 three-pointers in Saturday's thrilling clash.

It was not enough for the Warriors as Luka Doncic tied his career high of 42 points to inspire his side to a 134-132 victory, snapping a six-game home losing streak.

However, Kerr was blown away by Curry's shot-making ability, with the two-time MVP's 57 points - the second-best total of his career - coming on 19-of-31 shooting from the field.

"He's never played better," Kerr said. "We're talking about a two-time MVP, three-time champion. I've never seen him like this. He just looks so strong to me. 

"He's obviously always been an incredible shooter, but he looks stronger to me just getting by people, fending them off on drives to the rim, finish, and of course the shot-making. 

"It's almost unfathomable what he's doing out there."

Doncic, who is yet to outscore Curry in a head-to-head contest, was also amazed by the Warriors superstar's performance at the American Airlines Center.

"Every time he shot the ball, I thought it was going in," Doncic told ESPN. "It was something unbelievable. He's an amazing player. 

"He changed the game and it's always fun to play against him, and today we got a win, but it's always fun to play against him."

Elsewhere in Saturday's NBA action, champions Los Angeles Lakers beat the Detroit Pistons 135-129 in double overtime.

LeBron James had 33 points, eight of those points coming in the second overtime as the Lakers survived a scare against a Pistons side with just five wins all term.

James, who also had 11 assists to make it 10 double-doubles for the season, joked he is getting too old to be taken the distance.

"I was just ready to go," he said. "I'm 36 years old... my heart is not sustainable for two overtimes at this point in my career! 

"I've got a bottle of wine at home ready to be opened, and I delayed it for two overtime periods."
