Rebeka Masarova has earned her first Wimbledon victory…

Playing in only her second tournament at the All England Club, the unseeded 23-year-old Swiss-born Spanish professional tennis player defeated No. 31 seed Mayar Sherif in the first round.

Masarova, currently ranked No. 66 in the world, her highest ranking to date, outlasted Sherif 7-5, 3-6, 7-6 (6) in a hard-fought match.

Masarova will next face either Camila Osorio or Elisabetta Cocciaretto in the second round.

Earlier this year, Masarova reached her first WTA final at the Auckland Classic, losing to Coco Gauff 1-6, 1-6.
