Petra Kvitova is a two-time Wimbledon champion known for her powerful left-handed ground-strokes and variety.

Shortly before Christmas, she was robbed at her home in the Czech Republic, which resulted in tendon and nerve injuries to her left hand, and sidelined for six months.

However, she returned in May, one month ahead of schedule, but struggled at the French Open, losing to Bethanie Mattek-Sands in the second round in straight sets.

After a tournament win in Birmingham, she fell in the second-round at Wimbledon as well, where she had to call for medical assistance in her three-set loss to Madison Brengle.

"I was really trying hard to play Wimbledon and suddenly I was there and I wasn't feeling the best," Kvitova said this week as she prepared to launch her Stanford campaign.

"Everything together, physically, emotionally, mentally, it was just too much. The body just responded," Kvitova said.

After Wimbledon, she pulled out of a tournament in Bastad, but now she says she's healthy and ready to "enjoy the rest of the season."

She has booked herself for five tournaments in North America.

Seeded second, Kvitova enjoyed a first-round bye and will kick off her ambitious August against the winner of Tuesday's match between Italian Francesca Schiavone and Ukraine's Kateryna Bondarenko.
