Flushing Meadows, NY (My Sportsbook) - Surprise French Open titlist Gaston Gaudio went by way of the upset Thursday in second-round action at the U.S. Open.

Big-serving Swede Thomas Johansson sent the ninth-seeded Gaudio packing in 6-3, 2-6, 6-4, 6-4 fashion at the USTA National Tennis Center.

Gaudio, who typically excels on red clay, captured Roland Garros in June by stunning countryman Guillermo Coria in an all-Argentine final in Paris.

Johansson, who missed all of the 2003 season while recovering with a knee injury, won the Australian Open in 2002.

In other action involving top-16 seeds, No. 15 Thai Paradorn Srichaphan handled American Paul Goldstein 6-4, 7-6 (7-4), 6-0 and No. 16 Romanian Andrei Pavel dismissed Spaniard Fernando Verdasco 7-5, 6-3, 7-6 (7-2).

One of this summer's hottest players, German Nicolas Kiefer, advanced to round three with a hard-fought 7-6 (7-0), 6-3, 7-6 (7-4) victory over French shotmaker Cyril Saulnier. Kiefer, seeded 19th at this hardcourt fortnight, will encounter the resurgent Johansson in the round of 32 here.

Crafty Frenchman Fabrice Santoro blew past Russian Dmitry Tursunov 6-1, 6-3, 6-4. The 31st-seeded Santoro is rewarded with a third-round match against world No. 1 Roger Federer -- the reigning Australian Open, Masters Cup and two-time Wimbledon champ.
