The Golden State Warriors, Milwaukee Bucks and Brooklyn Nets were among the victors as the NBA’s inaugural in-season tournament began.

A last-second layup from Steph Curry was the difference for Golden State in their 141-139 group stage win over the Oklahoma City Thunder.

Curry finished with 30 points, eight rebounds and seven assists, while Lu Dort top-scored for the Thunder with 29.

It also went down to the wire in Portland, where the Trail Blazers eclipsed the Memphis Grizzlies 115-113 in overtime.

After a back-and-forth first half, neither side was able to gain much of an advantage through the final two quarters.

Shaedon Sharpe’s clutch free throws drew the Trail Blazers level with eight seconds left on the clock before he blocked Luke Kennard’s attempt from the corner on the other end to force overtime.

Both teams continued to trade baskets until Jerami Grant’s late three proved enough to get Portland across the line.

A late flurry from Damian Lillard lifted the Milwaukee Bucks over the New York Knicks 110-105.

He finished with 30 points, including two clutch threes in the dying minutes, while Giannis Antetokounmpo added 22 points and eight rebounds.

The Brooklyn Nets defeated the Chicago Bulls 109-107 on the back of 41 combined points from Dorian Finney-Smith and Mikal Bridges.

Elsewhere, the Miami Heat beat the Washington Wizards by seven points, Myles Turner scored 27 to lead the Indiana Pacers over the Cleveland Cavaliers 121-116, and the Denver Nuggets cruised past the Dallas Mavericks 125-114.

The in-season tournament sees each NBA team play a four-game group stage in November, with the group winners advancing to knockout rounds.

The winning team claims the NBA Cup, and its players earn 500,000dollars each, with the final to be played in Las Vegas on December 9.

Paul George believes the Los Angeles Clippers have found the right formula for success after stretching their winning run to four games with victory over the Indiana Pacers. 

Despite being without Lou Williams and Serge Ibaka on Sunday, the Clippers eased to a 129-96 triumph that improves their record to 10-4 this season. 

George was one of seven players to reach double figures for points, Marcus Morris Sr and Luke Kennard also matching the six-time NBA All-Star's tally of 20. 

The Clippers sit behind Los Angeles rivals the Lakers in the Western Conference standings and, after a difficult 2019-20 season that ended with a playoff collapse to the Denver Nuggets, they are "locked in" for this campaign, according to George.  

"The chemistry is amazing," he said after the win over the Pacers, according to quotes on ESPN. 

"It's a real bond. It's fun, with this team, it's locked in, we are together; it is one of the best locker rooms I have been around and been in. 

"Hopefully, you guys see it, just how well we are meshing. 

"We are going to continue to build off of that. We like where we are at and like where we are heading, we want to see this thing play all the way through."

Following the signings of George and fellow superstar Kawhi Leonard, the Clippers were considered among the title favourites last year. 

An all-Los Angeles Western Conference Finals appeared on the cards when the Clippers led the Nuggets 3-1 in their series in the Orlando bubble, only to then lose three games on the spin and crash out of the postseason.

Morris was part of that roster but sees differences now, insisting all those on the team are working in the same direction. 

"I feel like our energy is way better this season," Morris said. "Guys are buying in and enjoying playing the game." 

The Clippers appeared in danger of letting slip a big lead against the Pacers, who pulled within two points of their opponents early in the third quarter. 

However, the home team responded with a 37-14 run, moving clear as they coasted to victory. They are back in action on Wednesday, taking on the Sacramento Kings.
