After the match, she said that she was glad to have made the decision to play in Paris and that she was happy with the way she played, considering it was her first competitive match in over six months.

Graf's loss marked the first time in Wimbledon tournament history a defending champion lost in the opening round. "I mean, I know in the last years I had always up and downs and right now, of course, I'm. down". Indeed, she only regained her number one ranking after America's Serena Williams announced she was taking time off from the game as she expects the birth of her first child.

Despite a late rally in the second set, it was too little, too late as Kerber won only two of 16 break points in the entire match. She took 15 of the first 20 points en route to a 3-0 lead and never really faced a whole lot of resistance, other than when she saved three break points - the only ones she had to deal with in the match - while ahead 3-1.
She showed the weight of the occasion only at the end, dropping her racket to the clay and turning to her support camp with hand over mouth in disbelief. But that was about it.

She struggled to contain her emotions after seeing off American Julia Boserup, with a 6-3, 6-2 victory.
"I think it doesn't really matter how I played, but I won", the 15th-seeded Kvitova said.
