JOIN USThe 12th seed, who had fallen to qualifier Flavio Cipolla in the opening round at Madrid last week, never looked comfortable on the red clay against his unseeded opponent who cruised to victory after an early break. "He (Simon) moves really well which is not what you want to see when you're not hitting the ball well like today," Roddick told reporters.
The former world number one hit just nine winners compared to Simon's 23, making 27 unforced errors to the Frenchman's 18 on a windy Centre Court.
Roddick will next play in Nice before the French Open which begins on May 17. Simon, 19th in the world rankings, next faces the winner of the match between Argentine Juan Ignacio Chela and American John Isner.
In the women’s singles competition, Spain's Maria Jose Martinez Sanchez, who won the Italian Open 12 months ago as an unseeded player, failed to survive the first round on Monday as she stumbled to a 6-0, 5-7, 6-4 defeat by Russian Ekaterina Makarova.
In further upsets, 11th seed and former French Open champion Svetlana Kuznetsova fell 3-6, 7-6, 7-6 to unseeded Hungarian Greta Arn, while former finalist Patty Schnyder went down to Spanish qualifier Ana Medina Garrigues 6-3, 6-2. Another Spaniard Lourdes Dominguez Lino came through against Barbora Zahlavova Strycova 6-1, 0-6, 7-6.
