WARSAW, Oct. 7 (Xinhua) -- Poland's world No. 2 Iga Swiatek said on Saturday she will miss the Billie Jean King Cup in Sevilla, Spain as "the health remains a priority."

The 22-year-old beat Coco Gauff 6-2, 6-3 to reach the China Open final, and will face Liudmila Samsonova in Beijing on Sunday as the latter eliminated Kazakhstan's Elena Rybakina with a 7-6(7), 6-3 victory.

The Billie Jean King Cup will take place on November 7-12, while Swiatek's last tournament of the season could be the WTA Finals tournament, which will be played from October 29 to November 5 in Cancun, Mexico.

"I'm already feeling the hardships of this season and I can't imagine playing two tournaments just two days apart and at the same time having to deal with the consequences of a six-hour jet lag and another long trip after playing almost 70 matches this season," Swiatek said in a statement.

"The fact that I can now play in good health for a long time shows that, despite logistical difficulties and an intense calendar, my team and I are making the right decisions. It's a marathon, not a sprint," she added.

Swiatek emphasized that the tennis calendar of the ITF and WTA is too intense.

"I'm sorry that Polish fans are harmed, but health must be my priority. I don't know whether my decision will motivate the federation to change and enable me to play for the national team in the future without exposing my health to the risk of injury," the tennis player concluded.
