Martina Navratilova is the latest former tennis great to join the coaching ranks.
The 58-year-old Hall-of-Famer signed on to coach 2012 Wimbledon runner-up and current world No. 6 star Agnieszka Radwanska.
In a tweet, the Polish 25-year-old Radwanska referred to the Czech native/American citizen Navratilova as "the newest member of my coaching team."
The former world No. 1 great Navratilova, who piled up 18 Grand Slam singles titles as a player, said it "should be a fun ride."
Radwanska and Navratilova joined the recent trend of players hiring former greats as coaches, such as Andy Murray hiring Ivan Lendl and then Amelie Mauresmo, Novak Djokovic bringing in Boris Becker, Roger Federer partnering with Stefan Edberg, Marin Cilic working with Goran Ivanisevic, and Kei Nishikori welcoming Michael Chang.
