Federer books Djokovic clash

Roger Federer set up a semi-final showdown with Novak Djokovic in the Dubai Duty Free Tennis Championships on Thursday.

Federer recovered from an early deficit to thrash Lukas Rosol 6-2 6-2 in their quarter-final, winning 12 of the last 14 games to complete victory in just 58 minutes.

For the fourth set in a row Federer lost his opening service game to fall 2-0 behind, but he promptly broke back to love and won six games in a row to take the set.

The Swiss star had to save a break point to avoid losing his first service game in the second set, but then broke Rosol twice more to complete a routine success.

Earlier in the day, Djokovic had advanced to the last four without hitting a ball as quarter-final opponent Mikhail Youzhny was forced to pull out of their scheduled contest due to illness.

The other semi-final will see Germany's Philipp Kohlschreiber take on Tomas Berdych after Berdych beat Jo-Wilfried Tsonga and Kohlschreiber recorded the 300th match win of his career by beating wild card Malek Jaziri of Tunisia 6-2 6-3.

"It's always great to win many matches on the tour, especially a few rounds in a row," Kohlschreiber said. "I think I produced a very solid and good performance today. It's great that I have 300 victories under my belt."

One break of serve in each set was enough for second seed Berdych to beat Tsonga 6-4 6-3.
