MOSCOW (Reuters) - Maria Sharapova lost 7-6(3) 6-4 to Slovakia's Magdalena Rybarikova at the Kremlin Cup on Tuesday in her first match in Russia since returning from a doping ban this year.
The five-times grand slam champion looked tired and committed several unforced errors in the first-round match as she was cheered on by a large crowd cheered who chanted "Masha! Masha!" and loudly clapped her every winner.
Sharapova's first appearance at her home Women's Tennis Association event since 2007 came two days after she won her first WTA title in more than two years, the Tianjin Open.
Sharapova said that fatigue had not been a factor in her performance at the Kremlin Cup, crediting Rybarikova for a well-played match.
"I fought, I really tried to win this match but my opponent played well," Sharapova told a news conference after the match. "I felt fine physically given that I have just played five matches at the Tianjin Open."
The former world number one, now 57th in the rankings after rising 29 places following her Tianjin victory, returned to the tour in April after serving a 15-month doping ban for testing positive for meldonium at the 2016 Australian Open.
She was unranked by the WTA upon her return but received wildcards to many tournaments for which a ranking is usually required to compete, a situation that prompted criticism from her rivals.
Canada's Eugenie Bouchard in April called Sharapova a "cheater" and criticised the WTA for sending the wrong message by welcoming her back.
In Russia, Sharapova has been portrayed as a victim of what officials have said is the unfair targeting of the country by international sports bodies that regulate anti-doping.
Russia's athletics federation, Paralympic Committee and anti-doping agency have been suspended over WADA-commissioned reports that found evidence of state-sponsored doping.
