Head coach Paul Goriss will announce the signing coup on Friday morning, with Sykes to become the first Capitals' import on the roster since Canadian Kia Nurse and Frenchwoman Olivia Epoupa helped the side to its 2019/20 WNBL championship.

Sykes, who plies her WNBA trade with the LA Sparks, joins Alicia Froling, Kelsey Griffin, Mikaela Ruef, Kelly Wilson and Tahlia Tupaea on a rapidly improving Capitals' roster gearing up for another championship tilt this summer.

The 27-year old, who has also played basketball in Israel and Turkey, was drafted to Atlanta out of Syracuse in 2017 and has spent the last two years at LA.

"I'm actually really excited about coming to Australia, I have heard from a lot of people about how beautiful the continent is," Sykes said.

"With the pandemic raging so crazily across the world, it will be great to go to a beautiful place that also provides a sense of normalcy.

"I heard the league was a lot of fun and the fans were really passionate. That is similar to Europe, so I am used to it. I just hope that everyone knows that I am coming to win a championship."

Goriss was delighted with his latest acquisition.

"Brittney brings experience, speed defence and length to our backcourt," he said.

"She has an edge to her, she loves to compete, she wants to win, and she plays extremely hard.

"Speaking with Brittney and WNBA coaches they were all very complimentary on how hard she competes, her quickness, her defence and her toughness. She will be extremely exciting to watch."
