Flushing Meadows, NY (My Sportsbook) - Birthday boy and former champion Andy Roddick was an easy opening-round winner Monday at the U.S. Open.

The ninth-seeded former world No. 1 Roddick, celebrating his 28th birthday on Monday, blasted helpless Frenchman Stephane Robert 6-3, 6-2, 6-2 in 1 hour, 42 minutes on the grounds at the USTA Billie Jean King National Tennis Center. Roddick popped eight aces and had his serve broken only once in the predictable bout.

Roddick captured his lone Grand Slam title here seven years ago and was the 2006 U.S. Open runner-up to the great Roger Federer, who has beaten the American slugger in four major finales.

Fifth-seeded Swede Robin Soderling went the distance to hold off unheralded Austrian Andreas Haider-Maurer 7-5, 6-3, 6-7 (2-7), 5-7, 6-4 in just under four hours. The ever-improving Soderling is the reigning two-time French Open runner-up.

Sixth-seeded Russian Nikolay Davydenko cruised into the second round with a 6-4, 6-1, 6-3 pasting of American journeyman Michael Russell. The dangerous Davydenko looked strong, fit and fast on Day 1.

Eleventh-seeded Croat Marin Cilic handled Ukrainian Illya Marchenko 7-5, 6-3, 6-1, while 17th-seeded Frenchman Gael Monfils needed more than three hours to outlast American Robert Kendrick 3-6, 6-3, 6-4, 6-7 (5-7), 6-4. Cilic was an Aussie Open semifinalist back in January.

Former world No. 1 Juan Carlos Ferrero dismantled Slovakian Martin Klizan 6-1, 6-3, 6-0, while Croat Ivan Dodig upset 27th-seeded Fernando Gonzalez 6-7 (2-7), 6-1, 1-0. The former Aussie Open runner-up "Gonzo" retired in the third set against Dodig due to a knee injury. The 22nd-seeded former French Open champion Ferrero was the U.S. Open runner-up in 2003.

Additional opening-round wins came for Frenchman Richard Gasquet, Russian Igor Andreev, Brazil's Ricardo Mello, Japan's Kei Nishikori and Dutchman Thiemo De Bakker.

The champion here will collect at last $1.7 million.
