Second-seeded Caroline Garcia won her first tournament of the year with a 7-6 (7), 6-3 win over top-seeded Karolina Pliskova in the Tianjin Open on Sunday.
It was the 16th-ranked Garcia's first title since she won back-to-back trophies at the Wuhan and Beijing tournaments in Asia just over a year ago.
The Frenchwoman's two titles at the end of last season earned her a spot into the year-end WTA Finals in Singapore. This year, the victory in Tianjin is not enough to put Garcia into a second consecutive year-end final appearance.
Pliskova's failure to take the title also kept her from confirming a berth in the WTA Finals.
Currently in eighth place in the race to Singapore, the Czech will have to wait out the results from next week's tournaments in Luxembourg and Moscow to see if she qualifies for one of the three remaining spots. Pliskova is scheduled to play in Moscow.
American Sloane Stephens, Ukrainian Elena Svitolina and Dutchwoman Kiki Bertens are the other remaining contenders for Singapore.
Garcia was down 1-5 in the first set tiebreaker before she rebounded. She saved a set point for Pliskova at 5-6 to go on to win the hour-long first set.
In the second set, Garcia raced to a 5-0 lead, and first served for the match at 5-1, but had to wait for her victory to come three games later. She secured the title with her sixth ace of the match.
Danya wins WTA Title
HONG KONG: Ukrainian teen Dayana Yastremska won her maiden WTA title by upsetting sixth-seeded Wang Qiang of China 6-2, 6-1 in 65 minutes at the Hong Kong Open on Sunday.
The 18-year-old was playing in her first career WTA final in only her 11th career appearance in the WTA tournament main draw.
Yastremska is the sixth teenager to advance to a WTA final in 2018 and the second to win a title. Serbian teen Olga Danilovic won the Moscow River Cup earlier in the year.
Prior to arriving in Hong Kong, Yastermska held a 3-10 record in WTA-level matches this season. Her best previous result was reaching the 2017 Istanbul quarterfinals.
The victory, in which she posted 33 winners to 21 unforced errors, will move the 102nd-ranked Yastremska to a new career high ranking in the top 80 when the next rankings are released on Monday.
Yastremska's win prevented the 24th-ranked Wang from winning her third career title. Earlier this fall she won the Nanchang and Guangzhou trophies.
Wang, who was playing in her fifth consecutive tour semifinal, will move up to a career-high No 23 ranking despite failing to lift the title.
