ROME - Roger Federer lost to Italian wild card Filippo Volandri 6-2, 6-4 Thursday in the third round of the Rome Masters, extending his title drought to four straight tournaments and marking the worst stretch of his career since he rose to No. 1 in February 2004.

The top-ranked Swiss won in Dubai in March. He has since failed to win at Indian Wells, Key Biscayne, Monte Carlo, and Rome. Federer made 44 unforced errors to Volandri's 23.

Third-ranked Andy Roddick also had a rough day, losing 6-0, 6-4 to Juan Ignacio Chela. Roddick played his first tournament since injuring his hamstring in the Davis Cup last month. A stomach virus also slowed his preparation before flying to Europe.

Rafael Nadal extended his clay-court winning streak to 74 matches by rolling by Mikhail Youzhny.

--Fourth-seeded Martina Hingis couldn't overcome a hip injury, losing 6-4, 6-0 to Patty Schnyder in the third round of the German Open in Berlin. The injury cast doubt on whether Hingis, hurt again in her first event back after a six-week layoff for various ailments, will defend her title next week at Rome or play in the French Open.

Newly acquired defensive tackle Darwin Walker won't report to the Bills until he receives a contract extension. Acquired in a trade in March that sent linebacker Takeo Spikes to Philadelphia, Walker, a Walterboro native, said he hasn't visited Buffalo yet and will not report until a new deal is completed. Walker has two years left on his existing contract, but was attempting to negotiate a new deal with the Eagles.
