Nadal breezes past local hero
World No. 2 Rafael Nadal survived an injury scare to make the quarter-finals at Stuttgart's ATP tournament with a straight sets win over local hero Philipp Kohlschreiber.
Nadal, the tournament favorite, had to be treated for a knee injury early in his 6-3, 6-3 win over the German and admitted he was worried whether he could play on and stay on course for his sixth ATP tournament win of the year.
The Spaniard said it was a similar pain to the one he suffered in the final at Wimbledon this month, where he was beaten over five sets by Roger Federer.
The biggest upset of the day came when third seed Tomas Berdych was dumped out of the second round in straight sets by Spaniard Feliciano Lopez, ranked 74 places below him, who took just over 50 minutes to beat the world number 10.
Having been white-washed 6-0 in the first set, Berdych, who won his only title of the year so far at Halle last month, rallied briefly in the second set but went down 6-0, 6-3 to Lopez, who was to face compatriot Juan Carlos Ferrero yesterday.
Monaco beat Austrian Stefan Koubek 6-2, 3-6, 6-3 while sixth-seeded Ferrero had a tough time beating Argentina's Diego Hartfield in three sets in just more than two hours.
Radwanska on a roll
Third-seeded Agnieszka Radwanska of Poland extended her winning streak to seven matches by beating Klara Zakopalova 6-3, 6-4 on Thursday to reach the Palermo International quarter-finals.
The 18-year-old Radwanska won a minor tournament in the northern Italian town of Biella last week and reached a career-high No. 33 in the WTA Tour rankings this week
Zakopalova was the runner-up in this clay-court tournament in 2005 but had to qualify this year.
Fourth-seeded Emilie Loit advanced with a 6-1, 6-1 win over Kira Nagy of Hungary.
