WUHAN, China -- Garbine Muguruza got off to a winning start at the Wuhan Open. Jelena Ostapenko didn't.
Muguruza defeated Alison Van Uytvanck 6-4, 6-0 on Monday in the first round of the tournament, avenging a second-round loss to the Belgian at Wimbledon.
"I'm happy that I won this time. I remember the match from Wimbledon, like a very tough match for me," said Muguruza, who had been the defending champion at the All England Club. "It's always good to play again the same person that beat you, feeling good you did something much better than the previous match."
Muguruza will next face Swiss qualifier Viktorija Golubic, who defeated Sara Sorribes Tormo 6-3, 5-7, 6-4.
Ostapenko, who followed Muguruza as French Open champion in 2017, was beaten by Daria Gavrilova 6-2, 6-4.
Gavrilova, who won for only the second time in four appearances at the Wuhan Open, broke Ostapenko's serve five times. She will next play Barbora Strycova, who defeated Alize Cornet 6-3, 6-2.
Ashleigh Barty, a finalist last year in Wuhan, defeated Johanna Konta 7-5, 6-4 to advance.
Other winners included Aryna Sabalenka, Donna Vekic, Aleksandra Krunic, Dominika Cibulkova, Madison Keys and Wang Xiyu.
