In the women's singles, Tai had a 12-1 horrible head-to-head record to China's Chen Yufei before Saturday's match. However, it looked like Chen could crash Tai easily after lifting the first set 21-6.

"Today's wind above the court is stronger than the last two matches," Tai complained after the match. "I had to take a lot of effort to control the shuttlecocks, which made me on the difficult side."

After changing sides, Tai recovered to take the second set 21-13, forcing a third set, where Chen saw the match point first on 20-19, but Tai stayed calm and fought back for consecutive points to win.

Tai will play Spanish Olympic Champion Carolina Marin in the final after the latter ousted Japan's Sayaka Takahashi 20-22, 21-13, 21-18.
