The top eight players in the world have arrived in Cancun to battle it out for the season-ending Women's Tennis Association (WTA) Finals, scheduled to start tomorrow.

World number one Aryna Sabalenka of Belarus, competing as a neutral, has been drawn with Elena Rybakina of Kazakhstan, the fourth seed, Jessica Pegula of the United States, seeded fifth, and Maria Sakkari of Greece, seeded eighth in the Bacalar group.

Poland's Iga Świątek, seeded second, is teamed with Coco Gauff of the United States, the third seed, Ons Jabeur of Tunisia, seeded sixth and Markéta Vondroušová of the Czech Republic, the seventh seed, in the Chetumal group.

Sabalenka's main opponent will be Rybakina, with the latter winning 2-1 in head-to-head this season.

Despite claiming a Grand Slam title at the Australian Open, the Belarusian will be eyeing up closing the year on a high.

Sakkari, meanwhile will be high on confidence, after winning her second career title at the Guadalajara Open in September.

The Greek star, whose victory over Caroline Dolehide of the United States, helped her end a four-year drought, will be keen on building on the winning form.

Pegula, who had a good run in the US Open, will hope to rekindle her rivalry with Sakkari who leads 5-4 in the nine matches they have played against each other.

"Obviously with Aryna and Elena, it's girls with power games and big servers, so it's gonna be tricky," Pegula said.

"But I'm happy with my group.

"Aside from Maria, I actually haven't played Aryna or Elena that much, so it's going to be interesting."

With three Grand Slam champions in the mix, the Chetumal group offers more excitement, especially with Wimbledon champion Vondroušová set to face Jabeur in a rematch of the grass-court Grand Slam final.

The Tunisian suffered a painful and shocking defeat to the Czech star in the Wimbledon final this year and will hope to reverse the result this time.

Świątek will be hoping to get back the top ranking she lost to Sabalenka, after staying on top for 75 weeks, the third longest in WTA history.

Gauff meanwhile is in red hot form, having won her first Grand Slam on home soil this year.  

"You're not going to get any easy matches in WTA Finals," Świątek said.

"Obviously I faced Coco and Marketa in Beijing and US Open, so the only player I didn't play recently is Ons.

"I just have to focus on myself and get used to the conditions here and everything should be fine."

The WTA Finals starts tomorrow with Rybakina taking on Pegula, before Sabalenka faces Sakkari.

The top two from each group will advance to the semi-finals.

Defending champion Caroline Garcia of France has not qualified for the season-ending event.
