A Wimbledon ball girl floored by a player today said she was determined to return to SW19 in the hope of getting on Centre Court - and closer to her idol Roger Federer.

Erin Lorencin was shaken when 6ft 3in Frenchman Michael Llodra stretched to meet the ball, crashed into the umpire's chair and clattered into her.

The 15-year-old was crouching by the net on Court One when Llodra landed on top of her. The 29-year-old picked her up and gave her a hug to help her get over the shock.

Erin, who goes to Graveney School in Tooting, was left "a bit bashed up" by the collision but has insisted she is keen to get back on court. Speaking outside the family home in Earlsfield, her father Nendra said: "She was a bit shaken up at the time.

"But she composed herself and was fine by the time she got home, if a bit bashed up. She was just a bit embarrassed for that to have happened to her on television."

The 49-year-old architect revealed his daughter, who plays at her local tennis club, is desperate to be a ball girl in any of Federer's matches on Centre Court.

He said: "She may not get on to Centre as there are no guarantees, but, after this, I hope she does because it is every ball girl's dream. And she would definitely want it to be when Roger Federer is playing. He is her number one."

Llodra came off worse in the accident and was forced to retire from the second-round match against Tommy Haas after consoling Erin.

And that gave the chance for another ball girl to grab the limelight. Fifteen-year-old Chloe Chambers became an instant star when she was invited to knock up with Haas to entertain the 11,393 crowd.

And today Chloe, 15, joked that Hass could do with "a bit more topspin" on his forehand.

During one rally with the 24th seed she moved into the net to hit a winning volley - but revealed afterwards she only plays once a week with her uncle.

Chloe, who lives locally with her brother and three sisters, said Haas was her new favourite player.

The year 10 student at nearby Ursuline School said: "I'm just over the moon that I got to play on Court One with Tommy.

"It's just amazing, all the response I've had from my family and friends. I was very nervous to play in front of thousands of people. I just didn't want to muck up."

As she outplayed the German there were calls from the crowd of "Come on Tommy!"

Chloe started playing tennis when she was three and has taken part in the Wimbledon Junior Tennis Initiative.

And she said the experience had inspired her to play more. "I just love the atmosphere of Wimbledon and people shouting," she said.

"I saw him give a little clap at the end so I thought I did OK. I'm only a ball girl. I'm not a tennis player. To be handed the racket was amazing. I just wanted to get out there. I love tennis so much. I just wanted to play. Words can't describe how lucky I was."

Asked how Haas could improve his forehand, she joked: "Maybe a little bit more topspin."
