Italian fifth seed Sara Errani became Wimbledon's first major victim on Monday when she slumped to a 6-3, 6-2 defeat to Puerto Rican teenager Monica Puig. Errani, a semi-finalist at the French Open earlier this month and runner-up in Paris to Maria Sharapova in 2012, had gone into her first round clash carrying a groin injury which forced her out of Eastbourne last week. Puig, 19, the world number 65, who is playing a grass-court tournament for the first time as a professional, goes on to face either Japan's Misaki Doi or Silvia Soler Espinosa of Spain. Puig, who became the first Puerto Rican woman to reach the third round of a major at Roland Garros, took victory on a seventh match point.
