Maria Sharapova has suffered another injury setback in a frustrating 2017 as the Russian was forced to pull out of Stanford ahead of her second round match.
The five-time Grand Slam champion made the announcement on Wednesday.
“Unfortunately, I have to withdraw from today’s match,” Sharapova said in a statement. “Toward the end of Monday night’s match, I felt pain in my left forearm. After yesterday’s scan, the doctor has recommended I don’t risk further injury. Monday night’s crowd was so special and I wish I could continue playing, but I have to make a preventative decision.”
Sharapova, ranked 171st, defeated Jennifer Brady, 6-1, 4-6, 6-0, in her opener on Monday. This was the first WTA tournament she had played in the United States since 2015.
Sharapova had made her return from a 15-month doping ban in April before injury ruled her out of the grass-court season.
The Russian was slated to play seventh-seeded Lesia Tsurenko on Wednesday. With the walkover, Tsurenko will face either Madison Keys or Caroline Dolehide in the quarterfinals.
“This is definitely tough for Maria,” Bank of the West Classic tournament director Vickie Gunnarsson said. “She has so many fans, which was evident by the support she received here on Monday night. We wish her a speedy recovery and hope to see her back on the court soon.”
She is scheduled to play in the Rogers Cup in Toronto and Western and Southern Open in Cincinnati this month, but will have to go through qualifying to play at the U.S. Open if a wild card is not offered.
