Rusedski falls to Agassi

Agassi serves up a storm in Washington DC

Greg Rusedski lost consecutive tie-breaks to Andre Agassi as he crashed out of the Legg Mason Classic on Friday.

The Canadian-born left-hander powered to a one-set lead but was unable to put away the top seed, eventually going down 3-6 7-6 7-6 in a hard-fought quarter-final in Washington DC.

Both tie-breakers were desperately close, with Agassi stealing the first 8-6 and the second 10-8.

"I thought I had a really good chance," said Rusedski afterwards.

"There were a few interesting calls in the second set. It seems like the top guys always get the calls."

Agassi dismissed the latter observation as "absurd."

"I can assure you I get my share of bad calls. That was just, from any standpoint, a hard-fought great quality tennis match."

Roddick revels

The American now faces 10th seed Sjeng Schalken in the last four, after the Dutchman beat Jerome Golmard, of France, 4-6 6-4 6-2.

The second semi-final will be an all-American affair between Michael Chang and Andy Roddick.

Chang upset fourth-seeded Frenchman Fabrice Santoro 6-2 6-4, while Roddick, the ninth seed, earned a 6-3 6-4 victory over Chile's former world number one, Marcelo Rios.

"It was a pretty clean match today, there weren't any up-and-downs," said an elated Roddick afterwards.
