Souza the loser against Sousa Pity umpire Manuel Messina in the day's opening match on Court Central at the Geneva Open Monday when Portugal's sixth seed Joao Sousa took on Brazil's Joao Souza. For the record, Sousa won the first meeting between the players with near identical names 7-5, 6-3 to reach the second round at the claycourt tournament. To avoid confusion, though, Messina, from San Marino, was forced to state “Sousa Portugal” or “Souza Brazil” when calling the scores. The Geneva Open has been restored to the full ATP Tour for the first time since Thomas Muster won the 1991 title. Home favourite Stanislas Wawrinka is the top seed. Sharapova overtakes Halep Maria Sharapova of Russia jumped into second place in the Serena-Williams-dominated WTA rankings published Monday thanks to her third Italian Open crown. The double Roland Garros winner leapfrogs Romanian Simona Halep after her 4-6, 7-5, 6-1 Sunday win over Spain's Carla Suarez, who jumped two places to sit on 8th. Williams, who sat the Rome Open out due to an elbow injury, continues to dominate the women's rankings while her sister Venus is 15th. Further down, Ekaterina Makarova of Russia and Andrea Petkovic both dropped to ninth and tenth respectively. — Agencies
