World number one, Simona Halep, on Thursday pulled out of next week’s World Tennis Association (WTA) finals due to a lower back injury.
“It’s always difficult to withdraw from a big tournament. Actually, I think it’s the first time in my life. So it was a tough decision but it’s better for my health.
“My back is not OK. I didn’t practice for the last four weeks. I’m not ready to compete at this level and I’m still sore. It’s not easy to go on court and compete at this moment.
“The decision was tough for sure,” the 27-year-old Romanian said on her verified Twitter account of an injury sustained during training ahead of the Wuhan Open last month and later diagnosed as a herniated disc.
Halep has enjoyed a stellar season, which saw her reach the Australian Open final before winning her maiden Grand Slam title at the French Open.
“I wanted to finish 2018 on a high after such an incredible year, but sadly my back injury hasn’t healed the way we hoped it would and I need to put my long-term health first.
“I’m sad I won’t be able to play the fifth and final edition in Singapore, but I’m confident this is the right decision and will do everything I can to be back fighting my place at the WTA Finals next year.
“Singapore is a special city and I’m sure the fans will enjoy seeing some fantastic women’s tennis this week,” she added.
Despite withdrawing from Singapore, Halep is guaranteed to end 2018 as world number one for the second year in a row.
In her absence, Kiki Bertens, who finished ninth in the Race to Singapore standings, will be making her WTA Finals debut in the last version of the tournament in Singapore after a five year run in Southeast Asia.
The 26-year-old will be first Dutchwoman to compete at the season-ending showpiece in more than 20 years, since Brenda Schultz-McCarthy lost in the first round in 1997.
Bertens has won three tournaments this season, including a victory over Halep to claim the Cincinnati Masters title.
Angelique Kerber, Naomi Osaka, Petra Kvitova, Caroline Wozniacki, Sloane Stephens, Karolina Pliskova and Elina Svitolina have also qualified for the $7 million event which will move to Shenzhen next year.
