PARIS -- Japanese teenager Tokito Oda won the French Open wheelchair title to become the youngest man to win a Grand Slam tournament in any discipline, while Diede De Groot won the women's final Saturday for her 18th major singles title.
The 17-year-old Oda was seeded second and beat top-seeded Alfie Hewett of Britain 6-1, 6-4 on Court Philippe Chatrier for his first major title. The International Tennis Federation confirmed Oda's record, which excludes juniors, and listed his age as 17 years, 33 days.
Oda, who called it "the happiest day of my career," will overtake Hewett at the top of the rankings Monday.
"Two dreams come true," said Oda, who was beaten by Hewett earlier this year in the Australian Open final.
Hewett missed out on his fourth French Open title, his eighth major in singles and his 24th Slam overall.
Earlier, the 26-year-old De Groot of the Netherlands defeated second-seeded Yui Kamiji of Japan 6-2, 6-0 for her fourth title at Roland Garros, her 18th major in singles and 34th Slam overall.
De Groot is the reigning Paralympics champion.
