EASTBOURNE, England (AP) — Defending champion Petra Kvitova withdrew from the Eastbourne International on Tuesday citing fatigue.
No. 9-ranked Kvitova won her 31st WTA singles title on Sunday in Berlin.
The two-time Wimbledon champion was due to start her Eastbourne defense against Jelena Ostapenko, whom she beat in last year's final. Ostapenko won the 2021 title and the Birmingham trophy on Sunday.
Ostapenko beat Kvitova's replacement, Barbora Strycova, 6-4, 6-3 in the first round to set up a last-16 clash with Britain's Harriet Dart.
Kvitova followed the exit of Wimbledon titleholder Elena Rybakina on Monday. Rybakina was the top seed but withdrew because of a viral illness, Eastbourne organizers said.
