No. 2 seed Roddick into quarters at Japan Open

Andy Roddick beat Jeremy Chardy of France 6-4, 7-6 (4) on

Thursday to advance to the quarterfinals at the Japan Open.

The second-seeded American said Chardy is ”always dangerous

because he plays high-risk tennis” but felt more assured when

forced into longer rallies.

Roddick, playing his first ATP tournament since losing in the

second round of the U.S. Open, served only five aces but won 83

percent of his first serve points.

Rafael Nadal, the world No. 1 player, was scheduled to meet

Canadian Milos Raonic later Thursday.
