The 23-year-old Japanese did not have to play her second round match because her opponent withdrew.
Defending champion Naomi Osaka moved into the third round of the US Open without a fight. The 23-year-old Japanese did not have to play her second round match in New York on Wednesday because her Serbian opponent Olga Danilovic withdrew for medical reasons. The world number three Osaka is one of the favorites at the last Grand Slam tournament of the tennis season. In the third round, Osaka will now face Estonian Kaia Kanepi or Canadian Leylah Fernandez.
In the men's category, the number two seeded Russian Daniil Medwedew came easily into round three against the German Dominik Koepfer in three sets. His compatriot Andrej Rublew prevailed against the Spaniard Pedro Martinez in four sets.
Eliminated with only one set win, however, is the eighth-ranked Norwegian Casper Ruud against Botic van de Zandschulp (NED).
