The Associated PressTOKYO (AP) — Amanda Anisimova advanced to the quarterfinals of the Japan Women’s Open by beating seventh-seeded Zheng Saisai 6-1, 6-1 on Wednesday.
The 17-year-old American won 51 points to only 27 for Zheng to reach her first WTA quarterfinal match.
“I was playing a really good player, so I was just preparing myself well mentally,” Anisimova said. “I was just going out there without pressure and trying to have fun.”
Anisimova’s only other professional appearance outside her home country was at an ITF event in Curitiba, Brazil, in March 2017. She reached the final before losing to Anastasia Potapova.
Fifth-seeded Ajla Tomljanovic beat Zhu Lin 7-5, 6-4.
The 25-year-old Australian had 23 winners, including six aces, against Zhu.
Injured Sock out of Davis Cup
ZADAR, Croatia (AP) — Jack Sock is off the United States team for the Davis Cup semifinals against Croatia because of a hip injury and has been replaced by Ryan Harrison.
U.S. captain Jim Courier said Sock was hurt last week while playing in the doubles semifinals at the U.S. Open with Mike Bryan. Harrison was already on standby for the Davis Cup.
Said Courier: “it’s a factor in Davis Cup all the time, having to be prepared for these last-minute changes.”
Sock is ranked No. 17 in singles and No. 2 in doubles.
