PERTH, Australia (AP) - Seven-time Grand Slam tournament winner Venus Williams will represent the United States in the Hopman Cup mixed-teams tournament later this year for the first time in her career.

Organizers said on Wednesday the 32-year-old Williams will team up with big-serving John Isner at the tournament in Perth, Western Australia, from Dec. 29 to Jan. 5. The teams will play a men's singles, a women's singles and a mixed-doubles match in each contest.

Williams and Isner are the second big-name pair confirmed for the tournament after Serbia's Novak Djokovic and Ana Ivanovic.

Williams said, "I've never played the Hopman Cup, so for me it's going to be a wonderful experience.''
