Roddick forced out

Australian star progresses after Roddick injury

Home favourite Lleyton Hewitt is through to the third round of this year's Australian Open after Andy Roddick quit their contest.

Roddick took the first set of the battle of the former world number ones but he soon fell behind in the second following a stumble and it soon became apparent he had a problem with his leg.

At 3-0 down, the four-time Melbourne semi-finalist left the court for treatment.

When he returned, the 15th seed battled on gamely, but Hewitt's relentless chasing style is not suited to anyone carrying an injury and when the Aussie took the third set, Roddick decided it was time to call it a day.

The score was 3-6 6-3 6-4 at the time.

"It was a nightmare for both of us,'' said Hewitt.

"Obviously Andy stretched something and it's hard to concentrate for the player up the other end.

"Andy is such a great fighter so you know when he is struggling. - http://www1.skysports.com/
