Hingis having fun despite losses
Martina Hingis was unable to make a winning return to grand slam tennis but the former world number one is planning to continue her comeback.
Hingis came out of retirement for the second time last month following six years away from the WTA Tour.
At the moment she is just playing doubles - and has no intention of trying her hand at singles again any time soon.
Hingis has joined forces with old friend Daniela Hantuchova, but the pair have won just three matches in five tournaments.
They were unlucky with the draw in New York, which paired them against top seeds and defending champions Sara Errani and Roberta Vinci, who won 6-3 7-5.
Hingis returned to the court for her mixed doubles opener with India's Mahesh Bhupathi and this time lost two tie-breaks.
The 32-year-old said she is enjoying her comeback, but added: "I wish I was winning. Maybe that would help. We've been close pretty much every match.
"Maybe hard court is not the easiest one to come back to as well, playing eight weeks in a row.
"I enjoy it. I feel like I'm playing well. My body is screaming, 'What are you doing to me?' Definitely the nerves are there, not playing at a grand slam for six years doesn't really help either.
"I didn't have any problem with the speed of the game or anything. Errani is number five in the world, and I was still rallying with her and at the net I think I'm pretty good.
"The only thing that hurt me in the past was the serve. Today it's even more a key factor, especially in doubles."
Hingis won the singles title at Flushing Meadows way back in her standout year of 1997, and her match with Hantuchova was a big draw for the crowd.
She said: "I always enjoyed the big stage. Even today. You see the people that came. They enjoyed it. They really cheered us on. So I couldn't ask for more.
"I think to play in a stadium like this, it's really helpful. They really wanted us to do well and even win the (second) set and see a third set. You don't see such a crowd in women's doubles normally."
Hingis and Hantuchova will play their next tournament together in Tokyo next month, and the Swiss added: "I think we're just pretty much set up for the whole season and we'll see how it goes."
