Jiri Novak of the Czech Republic settled his game after a rocky start and beat Taylor Dent, 5-7, 6-1, 6-3, on Sunday to win the Japan Open for the sixth title of his career.

Novak, seeded fifth, upset top-seeded Lleyton Hewitt in the semifinals.

"I felt great the whole week," Novak said. "I beat some very good players here."

Novak also had a shot at the doubles title but abdominal pain forced him and countryman Petr Pala to quit while trailing 5-1 in the first set to Jared Palmer of the United States and Pavel Vizner of the Czech Republic.

"I started to feel it in the singles final," Novak said. "I thought I would be okay in the doubles, but it got worse after the break."

In the singles final, Novak began tentatively against the seventh-seeded American.

"We both started out nervously," Novak said. "But I was able to relax as the match went on and picked up some confidence in the second and third sets."

Dent broke Novak three times in the first set and looked poised for a quick victory. He repeatedly came to the net in the second set but Novak replied with returns just inside the lines.

Novak broke three times in the middle set to turn the match around. Dent committed seven double-faults and showed his frustration by hitting the ball high above the arena's retractable roof. Novak broke serve to go up 3-1 in the final set and then finished off Dent in a match lasting 1 hour 45 minutes.

Novak's semifinal was suspended for 35 minutes in the third set Saturday when rain from a typhoon leaked through the roof. Organizers opened the roof for the final, which was played under cloudy skies.

Wimbledon champion Maria Sharapova won the women's final Saturday with a 6-0, 6-1 victory over Mashona Washington of the United States.

Washington and countrywoman Jennifer Hopkins lost Sunday's doubles final, beaten, 6-1, 6-4, by top-seeded Shinobu Asagoe of Japan and Katarina Srebotnik of Slovenia.
