TOKYO -- Top seeds Rafael Nadal and Andy Roddick were straight-set winners Thursday in the second round of the Japan Open.

The top-seeded Nadal notched a 6-4, 6-4 victory over Canadian qualifier Milos Raonic, while the second-seeded Roddick posted a 6-4, 7-6 (7-4) triumph over France's Jeremy Chardy.

Nadal, the reigning French Open, Wimbledon and U.S. Open champ, has won each of his first two matches by identical scores. He is coming off a semifinal loss to eventual champion Guillermo Garcia-Lopez in last week's Thailand Open.

The two Spaniards could meet again in this week's semifinals, if both win their respective quarterfinal matchups.

Nadal will next take on Russia's Dmitry Tursunov, who advanced Wednesday with a win over Richard Gasquet of France. Garcia-Lopez also won his second-round match Wednesday against fellow Spaniard Feliciano Lopez and will next square off against Serbia's Viktor Troicki, who outlasted fourth-seeded Jurgen Melzer of Austria on Thursday, 7-6 (9-7), 3-6, 7-6 (7-3).

Next up for Roddick is fifth-seeded Frenchman Gael Monfils, who also reached the quarterfinals Thursday with a 6-4, 6-4 victory over Italy's Andreas Seppi. Monfils owns a 4-3 lifetime mark against Roddick, but the American has won two of the three matchups on hard courts. The two haven't met since the fourth round of last year's French Open, when Monfils dropped just nine games in a straight-set win.

Friday's remaining quarterfinal matchup will feature Finland's Jarkko Nieminen against Czech veteran Radek Stepanek. Both were second-round winners on Wednesday. Nieminen was last week's runner-up to Garcia-Lopez in Bangkok and started this week with a first-round upset of third-seeded and defending Japan Open titlist Jo-Wilfried Tsonga of France.
