Former world number one Martina Hingis, due to make her WTA comeback in doubles on Wednesday night, said she isn't considering a singles return.
"Not singles, no," Hingis, 32, said Wednesday, hours before she was to take the court with doubles partner Daniela Hantuchova at the WTA's Southern California Open.
"It's a completely different world. Even World Team Tennis now, it's brutal, it's only one set but still the next day you wake up, and you have to put so much more effort into it."
