The thrill of competition continues to motivate Martina Hingis even as she nears her 37th birthday.
"I always liked playing tennis, but being able to compete for championships, like here, not everyone gets to do that," Hingis said.
Hingis, a five-time Grand Slam singles champion and Wimbledon winner in 1997, has been playing only doubles the last several years.
She won four of the last five tournaments she has entered with partner Yung-Jan Chen of Taiwan, with the exception a loss in the semifinals at the French Open.
They advanced to the second round of the doubles tournament at Wimbledon on Friday, defeating Russian pair Natela Dzalamidze and Veronika Kudermetova 6-1, 6-3.
Hingis, who is from Switzerland, has also entered the mixed doubles tournament, partnering with Britain's Jamie Murray — who won the competition in 2007 with Serbia's Jelena Jankovic.
"He agreed to play, so I was pretty excited and looking forward to maybe playing (Saturday)," Hingis said.
