Puig provides first upset at Wimbledon

It didn't take long for the first upset to occur at Wimbledon, as Puerto Rico's Monica Puig ousted fifth-seeded Sara Errani on the first day of play at the year's third Grand Slam event.

Puig claimed a 6-3, 6-2 victory over Errani, who has not had much success on the grass courts at the All England Club. The Italian was making her sixth visit and has never been past the third round. Clay is clearly her favorite surface, evidenced by a surprise run to the final at the 2012 French Open and a semifinal appearance at Roland Garros this year.

It's the first Wimbledon appearance for the 19-year-old Puig, who reached the third round at the French Open.

Serbia's Ana Ivanovic battled through a tough first set against Frenchwoman Virginie Razzano, then rolled in the second to complete a 7-6 (7-1), 6-0 triumph. Ivanovic, seeded 12th this year, has advanced past the fourth round just once in eight previous Wimbledon visits -- a semifinal run in 2007.

Other early winners on Monday were Czech veteran Lucie Safarova and Italians Flavia Pennetta and Karin Knapp. Safarova, the 27th seed, eased past American Lauren Davis, 6-4, 6-0, while Pennetta toppled Britain's Elena Baltacha, 6-4, 6-1, and Knapp dumped Lucie Hradecka of the Czech Republic, 6-3, 6-4. Also, Lesia Tsurenko of the Ukraine earned a 6-1, 6-3 victory over Spain's Lara Arruabarrena.
