The eight players set to contest the season-ending WTA Finals have been confirmed.
Anett Kontaveit became the last player to qualify for the event in Guadalajara after a remarkable end-of-season run.
The Estonian triumphed at the Transylvania Open and overtook an injury-stricken Ons Jabeur in the world rankings to secure her place.
There are some notable absentees from the list of players competing at the WTA Finals, including world number one and defending champion Ashleigh Barty. She has returned home to Australia to prepare for next season.
Four-time Grand Slam winner Naomi Osaka is also missing. The Japanese star is still on a self-imposed break from the tennis court.
For the eight women who are competing, the WTA Finals offers a chance to win an incredible $5,000,000 (£3.7 million), the biggest prize pot in the history of tennis.
With the tournament now just around the corner, GiveMeSport Women takes a look at the eight players who will be competing to get their hands on this impressive reward.
Aryna Sabalenka
As world number two, Sabalenka will go into the WTA Finals as the top seed. The 23-year-old Belarusian has enjoyed a breakthrough year, and she will be looking to end it in the best way possible.
Sabalenka began her season with victory at the Abu Dhabi WTA Women's Tennis Open, before defeating Barty to win the Madrid Open in May. She also reached the semi-final at both Wimbledon and the US Open.
It will be Sabalenka’s first time playing at the WTA Finals.
Barbora Krejčíková
Krejčíková is another player making her WTA Finals debut. The Czech star qualified alongside Sabalenka as the world number three.
The 25-year-old enjoyed an astonishing purple patch in May and June, going unbeaten for eight weeks. This period included Krejčíková’s first WTA title at the Strasbourg Open and her first Grand Slam title at Roland Garros.
Krejčíková eventually lost to Barty in the fourth round of Wimbledon, but she went on to win the Prague Open and reach the US Open quarter-finals.
Karolína Plíšková
Plíšková had a difficult start to the year, falling in the early rounds of the majority of tournaments she played in. She did reach the final of the Italian Open, but suffered an embarrassing 6-0, 6-0 defeat to Iga Świątek.
The Czech 29-year-old fell out of the world top 10, but crept back in after reaching the final of Wimbledon. She lost to Barty, but went on to make the Montréal Open final, Cincinnati Open semi-final, and US Open quarter-finals.
It will be Plíšková’s fifth successive appearance at the WTA Finals.
Maria Sakkari
Sakkari made history when she became the first Greek tennis player to qualify for the WTA Finals.
The 26-year-old showed her top 10 credentials when she ended Naomi Osaka's 23-match winning streak on her way to the Miami Open semi-final in April.
Sakkari then progressed to the semi-final of the French Open, losing to eventual winner Krejčíková, before achieving a second career Grand Slam semi-final at the US Open. She was again defeated by the eventual champion, Emma Raducanu.
Iga Świątek
Despite winning the French Open last year, this will be Świątek’s first appearance at the WTA Finals. The 20-year-old Pole was unable to defend her title at Roland Garros this year, but claimed two WTA titles.
The first came at the start of the season at the Adelaide International, followed by victory on her favoured clay court at the Italian Open.
Garbiñe Muguruza
Spain’s Muguruza will be competing at her fourth WTA Finals of her career. She got her year off to a good start by winning the Dubai Open, but her clay season was derailed by injury.
After disappointing showings at Roland Garros, Wimbledon and the US Open, the 28-year-old got back to winning ways at the Chicago Open.
Paula Badosa
Badosa could soon surpass Muguruza as the best Spanish player on the women’s circuit, having enjoyed a breakthrough year which has culminated in qualification for the WTA Finals.
The 23-year-old earned her first WTA title at the Belgrade Open, before progressing to the quarter-final at Roland Garros.
Badosa really made a name for herself at Indian Wells last month. She became the first Spanish player to win the tournament, defeating Coco Gauff, Krejćíková, Angelique Kerber, Ons Jabeur and Victoria Azarenka along the way.
Anett Kontaveit
Kontaveit snuck into the WTA Finals, capitalising on an injury to her nearest rival Jabeur to grab the last spot.
The 25-year-old Estonian has enjoyed a meteoric rise up the WTA standings after winning four titles in two months – Tennis in the Land, Ostrava Open, Kremlin Cup and Transylvania Open.
Kontaveit held her nerve to defeat home favourite Simona Halep in the final in Cluj-Napoca, and will now make her debut at the WTA Finals.
The WTA Finals are scheduled to run from November 10th to 17th in Guadalajara.
