(Reuters) -Wimbledon champion Elena Rybakina remained in contention for a WTA Finals spot with a 7-6(5) 6-2 win over Karolina Pliskova in the first round of the Guadalajara Open on Tuesday.Pliskova served for the opening set at 5-3 but the Czech was unable to finish the job as Rybakina battled back to force a tiebreak.
Pliskova issued one of her six double faults in the match on set point in the tibreaker and Rybakina cruised from there, taking the second set behind her powerful groundstrokes and booming serve.Next up for Rybakina is a meeting with American Jessica Pegula, who won their only previous meeting at the Miami Open this year.
The WTA Finals will be contested by the game's top eight players, with Iga Swiatek, Ons Jabeur and Pegula having locked up the first three spots.
Rybakina can book her spot by winning the title in Mexico. The Finals kick off on Oct. 31 in Fort Worth, Texas. Canadian Bianca Andreescu rallied to beat Petra Kvitova 3-6 6-2 6-0 and will meet either Rybakina or Pegula in the third round.After a strong start, Kvitova's serve began to betray her and she issued eight double faults and was broken for an eighth time in the final game of the contest to end her season.
