Former world number one Martina Hingis will come out of retirement for the second time tonight.

The five-times Grand Slam champion is teaming up with Daniela Hantuchova to play in the doubles at the Southern California Open.

Hingis is still just 32 but it is not clear whether she plans to return to singles competition.

The Swiss originally retired in 2003, returning to the WTA Tour in 2006, before calling it a day again a year later.
