The WTA season may be over, but the game's biggest stars are still headlining stadiums around the world, none bigger than a pair of former No.1s in Maria Sharapova and Ana Ivanovic, who returned to the International Premier Tennis League for a second straight year.

Playing women's singles and mixed doubles, Sharapova won both of her sets for the Legendari Japan Warriors team, but it wasn't enough to overcome the Micromax Indian Aces led by top ranked doubles player Sania Mirza and 2011 US Open champion Samantha Stosur, who ultimately won the series, 25-24.

Ivanovic had better fortunes playing for the OBI UAE Royals - with an assist from Kristina Mladenovic. The Serb won a 6-3 women's singles set against Belinda Bencic, who was playing for the OUE Singapore Slammers, before Mladenovic stepped in for a mixed doubles win with Daniel Nestor over good friend Karolina Pliskova, who partnered Marcelo Melo. The Royals dropped just one set to the Slammers, and took the match, 26-20.
