ATP: Nadal wins; Hewitt bows out in London

London, England (Sports Network) - Top-seeded Rafael Nadal posted a second- round victory, while defending champion Lleyton Hewitt came up a loser Wednesday at The Artois Championships, a grass-court Wimbledon tune-up.
The reigning three-time French Open champion Nadal made a smooth transition to grass with a 6-4, 6-4 win against promising Argentine Juan Martin del Potro on Day 3 at The Queen's Club. The Spanish Nadal won 40-of-46 points on serve en route to victory.
The 2006 Wimbledon runner-up Nadal is fresh off his championship at Roland Garros, where he defeated the great Roger Federer in the final for a second straight year.
The sixth-seeded Hewitt, meanwhile, was stunned by big-serving French qualifier Jo-Wilfried Tsonga 7-6 (7-5), 7-6 (7-2). The former world No. 1 and former Wimbledon champion Hewitt topped American James Blake in last year's Queen's Club finale and also captured this event back-to-back-to-back from 2000-02.
Three other stars avoided Day-3 upsets here, as third-seeded Chilean Fernando Gonzalez snuck past Serbian Janko Tipsarevic 7-6 (9-7), 4-6, 7-6 (9-7), fourth-seeded Serbian Novak Djokovic overcame American Robert Kendrick 3-6, 6-3, 6-2 and seventh-seeded Russian Dmitry Tursunov doused Canadian Frank Dancevic 7-5, 6-1. Gonzalez was January's Aussie Open runner-up to Federer, while Djokovic was a semifinal loser against Nadal at Roland Garros last week.
