Klay Thompson recalled his lowest moments from an extended time on the sidelines after posting his best scoring performance of the season on Monday.

Thompson, who missed over two and a half years through injury before returning to the court last January, scored 54 points as the Golden State Warriors sealed an overtime win against the Atlanta Hawks.

The 32-year-old, who also had eight rebounds and three assists, made 21 of 39 field goal attempts and 10 of 21 from beyond the arc as the Warriors won 143-141 at Chase Center.

"It's better than good, [it's] amazing,'' Thompson said after his performance. "Those moments where you have the ball with the game on the line down the stretch and your team-mates trust you, those are what you really live for as a competitor, as a basketball player. It was hard to see those at times during the rehab process."

The defending NBA champions have struggled on the road this season, but their far more reliable home form saw them move to 20-18, with 17 of those wins coming at Chase Center.

Coach Steve Kerr was particularly pleased with the effort of Thompson, saying: "He just made shot after shot and play after play, he was incredible."

Kevon Looney scored the winning basket right at the final buzzer in second overtime, making up for a miss just prior, and laughed when asked if he had ever scored a game-winner before.

"Not a walkoff game-winner," Looney said. "I rushed the first one. I didn't think I had that much time, but I saw I had more time, so I took my time on the second one and I was able to make it."

The Golden State Warriors have retained a key member of their NBA championship team by agreeing to a three-year, $25.5million contract with forward Kevon Looney, ESPN reported on Friday.

A first-round pick of the Warriors in 2015, Looney started a career-high 80 regular-season games in 2021-22 and emerged as a valuable complementary contributor to Golden State's fourth NBA title in eight years.

The 26-year-old averaged just 6.0 points per game during the regular season but was among the Warriors' top rebounders at 7.3 per game while providing a strong interior defensive presence.

Looney also chipped in a couple of standout performances during Golden State's title run. The seven-year veteran grabbed 22 rebounds – one short of a franchise single-game postseason record – in a series-clinching Game 6 win over the Memphis Grizzlies in the second round, then later amassed 21 points on 10-of-14 shooting along with 12 boards in a Game 2 victory over the Dallas Mavericks in the Western Conference Finals.

Keeping Looney was a top priority for the Warriors, who will be losing two other important rotation players in free agency in forward Otto Porter Jr. and guard Gary Payton II.

Porter agreed to a two-year contract with the Toronto Raptors, according to Yahoo Sports, while The Athletic reports that Payton will sign a three-year, $28 million deal with the Portland Trail Blazers.

Stephen Curry avoided injury late in the first half of the Golden State Warriors' 109-100 win over the Dallas Mavericks on Sunday after he tripped over a vendor at court-side.

Curry fell over the unsuspecting man serving drinks in the final seconds before the main interval as he scrambled to close out on a Reggie Bullock three-point attempt.

With his extensive history of ankle injuries, the former unanimous MVP was visibly frustrated with the accident, but went on to score 31 points as the Warriors took a 3-0 series lead over the Mavs.

Curry's frustration was not directed at the vendor however, which he clarified post-game.

"Yeah, man, there's like 30 seconds left before half-time, you're ordering a drink," Curry said after the game. "Just wait until half-time. I don't know why they needed to deliver it right then, but thankfully I was alright.

"He [the vendor] was doing his job, so hopefully he got a big tip."

Curry shot an even 50 per cent on his way to those 31 points, while adding 11 assists and five rebounds in the win.

Rebounds were big for the Warriors, especially on the offensive glass, with Kevon Looney and Andrew Wiggins combining for 10 while the Mavs grabbed seven as a team.

Looney had only seen over 20 minutes twice over the two series against Denver and Memphis, but following his double-double of 21 points and 12 rebounds in Game 2, pitched in with nine points, 12 rebounds and four assists on Sunday.

Curry singled out Looney for praise following the game, highlighting him as a reflection of the team's identity. 

"It's a testament to how things change in the playoffs, from series to series and even within that from game to game, where you've got to have everybody stay ready," he said.

"Loon comes in Game 6 [against Memphis] and makes a huge difference, has a career night rebounding the ball. In this series, he's had career nights and had an amazing impact.

"It's how we do things, with everybody being a part or being a factor at some point, but it's how the playoffs go. You just love to see a guy get rewarded for staying ready."
