Local boxer Natalia Shadrina triumphed in her second bout here at the International Boxing Association (AIBA) Women's World Championships.
Hailing from the host city, Shadrina is the captain of the 10-strong Russian team here.
Having eased through the opening round of the lightweight division, the 29-year-old came up against 37-year-old Laishram Sarita Devi of India, a veteran boxer and winner of the world title in 2006.
The home crowd were delighted as Shadrina recorded a unanimous victory against Sarita.
Her next opponent is scheduled to be Dayana Cordero of Colombia, who had her contest against Naomie Yumba of the Democratic Republic of Congo stopped by the referee.
Recently-crowned Pan American Games champion, Beatriz Ferreira of Brazil, received a walkover after opponent Keamogetse Kenosi of Botswana withdrew from competition.
