The Phoenix Suns have signed star guard Devin Booker to a multi-year contract extension, which ESPN reported was worth $145 million over two years.

The reported figures — with an annual extension salary of $72.5 million — would make it the largest annual average salary extension in league history.

And while the Suns didn’t confirm the numbers, they were clearly delighted to have secured the four-time All-Star, a two-time Olympic gold medallist with the United States who averaged more than 25 points per game in each of the past seven seasons.

“Devin Booker is the embodiment of the Phoenix Suns, representing the best of our organisation, our community and our future,” Suns owner Mat Ishbia said in a statement.

ESPN reported the deal will keep Booker in Phoenix through the 2029-30 season, and in terms of annual salary eclipses the four-year, $285 million extension agreed by Oklahoma City Thunder star Shai Gilgeous-Alexander this week.

Booker has played all 10 of his NBA seasons for the Suns and last season became the team’s all-time leader in total points scored.

He helped the Suns reach the NBA Finals in 2021, when they lost to the Milwaukee Bucks, and his continued presence will provide stability for a Phoenix franchise now in transition after a disappointing 2024-25 campaign.

The Suns had the highest payroll in NBA history after investing in Kevin Durant and Bradley Beal. But they missed the playoffs and fired coach Mike Budenholzer in April.

Two-time NBA champion Durant has since been traded to the Houston Rockets as part of an unprecedented seven-team deal in which players obtained by Phoenix included 18-year-old South Sudanese rookie Khaman Maluach — the 10th overall draft pick in June — along with forward Dillon Brooks and guard Jalen Green from Houston.

In June, the Suns named 40-year-old Jordan Ott head coach, Ishbia pointing to Ott’s “track record of developing players (and) fostering team chemistry” in naming Ott to his first head coaching position.

THUNDER MAKE $822M STATEMENT TO WRAP UP BIG THREE

Elsewhere, the NBA champion Oklahoma City Thunder agreed a five-year contract extension worth up to $287 million with 24-year-old All-Star forward Jalen Williams, ESPN reported.

ESPN cited Williams’s agents in reporting the extension of Williams’s rookie contract — which makes the 24-year-old the latest key piece of Oklahoma City’s title run to commit to the Thunder long-term.

Shai Gilgeous-Alexander, the regular-season and NBA Finals MVP, signed a four-year, $285 million extension on Wednesday and big man Chet Holmgren reached a $250 million five-year extension on his rookie contract on Thursday.

With the deals done, the 20-something trio look set to compete for titles for the foreseeable future.

The Thunder became the second-youngest team in history to claim the NBA title when they beat the Indiana Pacers in seven games in the NBA Finals last month.

The Thunder crowned a dazzling 68-win regular-season with the first championship since the club relocated to Oklahoma City in 2008, the franchise had won the title as the Seattle SuperSonics in 1979.

Williams, whose extension will keep him in Oklahoma City through the 2030-31 campaign, averaged 21.6 points, 5.3 rebounds and 5.1 assists in the regular season and 21.4 points, 5.5 rebounds and 4.8 assists in the playoffs.

He revealed in a YouTube video this week that he received “28 or 29” painkilling injections as he played through a torn ligament in his right wrist.

He said he suffered the injury in April, when he was already playing through a sprain in the same wrist.

Williams, taken 12th overall by the Thunder in the 2022 NBA draft, was impressive in the Finals, increasing his scoring total in each of the first five games as he went from 17 points in game one to 19 in game two, 26 in game three, 27 in game four and a dazzling 40 in game five.

Williams had surgery on his injured wrist on July 1 and was scheduled to be reevaluated in 12 weeks, the team said.

“He powered through,” Thunder general manager Sam Presti said.

“He showed incredible mental endurance and security in himself … I thought it was pretty impressive that he just kept moving along with no excuses and obviously played his best basketball down the stretch of the season.”
