Former world No. 1 Martina Hingis says she will continue to play with doubles partner Daniela Hantuchova after the U.S. Open. Since the Swiss returned to the WTA at the start of August, she has compiled a 3-5 record in doubles. Their next stops will be in Tokyo and Beijing.

The 32-year-old, who has played for five consecutive weeks, admits that her tour return has taken a physical toll on her.  
“It's different playing matches than playing like practice and practice,” she said. “Coaching, it's like still the player has to play the matches, not me.  
Hingis, who double faulted three times in the final game of her and Hantuchova’s loss to top seeds Sara Errani and Roberta Vinci, added: “The only thing that hurt me in the past was the serve. Today it's even more a key factor, especially in doubles.”
