Former world No. 1 Martina Hingis will play for the Washington Kastles this season. Hingis, 32, was selected by the two-time defending champions in the World TeamTennis roster draft. She has a 20-4 record in WTT singles the last two seasons and is the reigning WTT female most valuable player.

Hingis will join the Kastles for their final nine matches and be available for the playoffs, which will be held on the last weekend in July, and will be hosted by the Kastles provided Washington has the best regular season record in the Eastern Conference. Washington will enter the year with a 32-match winning streak, the longest in league history.

“I’m really excited about joining the Washington Kastles,” Hingis said in a statement. “The team and its owner (Mark Ein) are building a great legacy and I look forward to contributing toward that. Washington is a great city and the Kastles have a fantastic fan base. I can’t wait to get started in July.”

Hingis will join Kastles mainstays Leander Paes, Venus Williams, Anastasia Rodionova, and Bobby Reynolds, last year’s male MVP of the league.

“On paper this is the best team the Washington Kastles have ever assembled,” coach Murphy Jensen said, “I also see it as the best team ever put together in WTT.”
