Federer Wins; Gonzo, Nalbandian Save MPs at Basel

Fish led 6-2 in the third-set breaker, but Gonzalez won the next four points. The Chilean then saved two more match points before Fish double-faulted on the last point. Gonzo now will face Argentine teen Juan Martin del Potro, a 6-3, 6-2 victor over George Bastl.

Playing in front of his Swiss fans, world No. 1 Roger Federer earned his 21st straight match win with a 6-2, 6-0 destruction of Guillermo Garcia-Lopez.

"I'm playing unbelievable right now," Federer said to the press afterward. "To take control of the match the way I did today was surprising...I felt like I couldn't miss much."

Federer has never won his home tournament in Basel.

Also, David Nalbandian saved a match point in his win over Spaniard Feliciano Lopez 6-7(4), 6-3, 7-6(7).

Awaiting Nalbandian in the quarterfinals is Federer's countryman Stan Wawrinka, who upended Tim Henman 2-6, 7-6(5), 6-4. Henman injured his knee in the loss, likely ending his season.

Also advancing to the quarterfinals were Jose Acasuso and Paradorn Srichaphan. The seventh-seeded Argentine defeated Philipp Kohlschreiber 7-6(2), 6-1 while the Thai star upset Juan Ignacio Chela 6-4, 6-3.
