Brittney Griner plans to sign with the Atlanta Dream, marking the end of her 11-year career with the Phoenix Mercury.

Griner announced the move in a video posted to Instagram on Tuesday night, and her agent, Lindsay Kagawa Colas, confirmed to The Associated Press that the star center would sign a one-year deal with Atlanta.

“Free agency has been everything I wanted it to be, honestly. I was able to find where I wanted to go,” Griner said in the video. “Honestly, what led me to that decision ultimately was the team, the players. Also my family. I’m thrilled for this chapter.”

WNBA free agents can’t sign contracts until Feb. 1.

The 6-foot-9 Griner had spent her entire career with Phoenix since getting drafted No. 1 in 2013. Now 34, she decided this offseason to test free agency for the first time. Griner is signing for only one year because a new collective bargaining agreement featuring potentially massive salary increases is expected to take effect in 2026.

“It was a hard decision since you’re leaving what you know. What I’ve known for my whole career,” she said. “There’s an exciting factor of like, OK, this is a rebrand now. I get to show them something different.”
