WNBA star accused of having affair with married NBA executive, lawsuit reveals

A new lawsuit alleges former Phoenix Mercury player Sophie Cunningham had an affair with Josh Bartelstein, the married CEO of the Phoenix Suns and Mercury.

The lawsuit, filed by Gene Traylor, the Suns’ former director of safety, security and risk management, accuses the organization of racial discrimination and includes claims of organizational misconduct.

Traylor alleges that Cornelius Craig, the Suns’ vice president of security and risk management, spread damaging rumors about Bartelstein’s alleged relationship with Cunningham, 28.

Traylor claims he reported these concerns to Bartelstein, who did not take action.

“When Bartelstein asked Plaintiff to reveal what Craig was saying, Plaintiff explained that Craig had been telling others, ‘Josh Bartelstein is f–king Sophie Cunningham,’” the lawsuit reads.

The Independent has contacted representatives for the Suns, the Mercury, Fever, and Cunningham for comment.

Stacey Mitch, the Senior Vice President of Communications for the Suns, denied these allegations in a statement to The Independent.

“The recent reports concerning Josh Bartelstein and Sophie Cunningham are entirely false and morally reprehensible,” she said.

Mitch also criticized Traylor’s attorney, Sheree Wright, noting her disciplinary history with the Arizona State Bar.

“She continues to insert salacious lies and fabrications into her complaints—knowing that the media may report them as fact, as happened yesterday—she hopes to coerce the Phoenix Suns into settling. Sheree Wright will not extort our organization and never see a single dollar,” Mitch said.

Cunningham played for the Mercury from 2019 to 2024 after being drafted by the team in the second round of the 2019 WNBA Draft.

Although she signed a contract extension through 2025 last September, she was traded to the Indiana Fever in February.

Cunningham did not play in the Fever’s season opener against the Sky on Saturday due to an ankle injury.

Bartelstein, a former Michigan basketball player, became CEO of the Suns and Mercury in April 2023 after spending eight years with the Pistons. He has been married to his wife Sydney, for two years.

Bartelstein shouted out his supportive wife in a November 2024 profile for Phoenix Magazine.

“This job is incredibly demanding. It’s the best job ever, but it’s long hours, high-stress and -pressure, and public-facing. And I travel a lot,” he said. “Me and Sydney have done it together, and she’s a huge reason why I love what I get to do.”
