- Paradorn Srichaphan overcame 15 aces by Wesley Moodie of South Africa in a 6-3, 7-6 (1) victory in the third round of the Legg Mason Tennis Classic on Thursday night.
Srichaphan, seeded 13th, won just 20 hours after playing through stomach pains in a three-set win over Paul Goldstein.
Hard-hitting Ivo Karlovic of Croatia also advanced to the quarterfinals with a 7-6 (4), 6-2 win over 11th-seeded Greg Rusedski of Britain. Karlovic had 14 aces in the match, bringing his tournament total to 60, and won 95 percent of his first-serve points in knocking off his second straight seeded opponent.
``It was hot, and I think in the second set he was a little bit tired,'' the 6-foot-10 Karlovic said. ``I think that I am playing well here, and I am happy that I am in the quarterfinals.''
Rusedski becomes the ninth seeded player to be ousted from the U.S. Open Series event. Top-seeded Andy Roddick was the lone player among the top eight seeds still alive entering play Thursday. He played 14th-seeded Juan Ignacio Chela of Argentina Thursday night.
Karlovic will face the winner of the Roddick-Chela match Friday.
Unseeded Arnaud Clement of France advanced to the quarterfinals, defeating Gilles Muller of Luxembourg 4-6, 6-3, 6-4.
James Blake, the 2003 tournament champion, was also set to play Thursday night against 16th-seeded Thomas Zip of the Czech Republic.
