ATP: Roddick reaches semis; Nadal bows out in London

London, England (Sports Network) - Three-time champion Andy Roddick was among Friday's quarterfinal winners, while French Open champ Rafael Nadal was shown the exit at the grass-court Artois Championships, a Wimbledon tune-up.
The top-seeded Nadal saw double duty on Day 5 and was not able to advance in his latter bout.
Earlier in the day, the 2006 Wimbledon runner-up Nadal completed a 7-6 (7-3), 6-3 victory over Belarusian Max Mirnyi. The Spaniard was leading 5-3 in the second set when that match was suspended because of rain here on Thursday.
In his second bout on Friday, Nadal was ousted by Frenchman Nicolas Mahut 7-5, 7-6 (7-0) at The Queen's Club. Nadal was fresh off his third straight title at the French Open, where he, of course, excels on the red clay at Roland Garros.
Mahut started his day Friday by stunning fifth-seeded Croat Ivan Ljubicic 7-6 (7-3), 6-3 in the third round. Rain forced the suspension of that match here on Day 4.
The second-seeded Roddick, meanwhile, avoided an upset by handling Croatian wild card Marin Cilic 6-4, 7-6 (7-5). The former world No. 1 Roddick captured this London event back-to-back-to-back from 2003-05.
Another quarterfinal upset came when seventh-seeded Russian Dmitry Tursunov tripped up third-seeded Aussie Open runner-up Fernando Gonzalez of Chile 6-3, 6-7 (5-7), 6-4.
One other quarter saw 14th-seeded Frenchman Arnaud Clement dismiss 6-foot-10 Croat Ivo Karlovic 7-5, 6-4. Earlier in the day, Clement stunned fourth-seeded Serbian Novak Djokovic 2-6, 6-3, 6-4 in third-round action. Djokovic was a semifinal loser at the hands of Nadal last week in Paris. Karlovic lost to Roddick in the 2005 Queen's Club finale.
Saturday's semis will pit Roddick against Tursunov and Clement versus his fellow Frenchman Mahut. Tursunov bested Roddick in an epic Davis Cup rubber last year, as he propelled the Russians into the final with a five-set victory over the American, including a 32-game (17-15) fifth set win.
