Briton Lily Miyazaki lost in the Wimbledon second round as she failed to win a game against Daria Kasatkina.
The Russian 14th seed - who won the Eastbourne title on Saturday - came through 6-0 6-0 in 50 minutes.
World number 148 Miyazaki produced the biggest win of her career when she beat Tamara Korpatsch in the first round, but could not replicate her performance.
Miyazaki, 28, struggled to keep the ball in play, with 31 unforced errors among the 53 points won by Kasatkina.
Kasatkina, 27, will play Spaniard Paola Badosa in the third round.
