Japan's Shingo Kunieda and Yui Kamiji won French Open wheelchair singles championships on Saturday.

It was Kunieda's seventh men's title at Roland Garros, while Kamiji, the defending champ, won her third women's championship.

The 34-year-old Kunieda, who entered the Grand Slam event ranked third in the world, defeated No. 2 Gustavo Fernandez of Argentina 7-6(5), 6-0 in 1 hour, 47 minutes. With his 22nd career Grand Slam championship, Kunieda will regain his world No. 1 ranking.

"My emotions were running high," said Kunieda, a two-time Paralympic champion. "I battled well to win the first-set tiebreak's first point, and that swung the momentum my way. Gustavo made a lot of mistakes in the second set."

Kunieda, who had right elbow surgery two years ago, has now won two straight Grand Slams. His Australian Open victory this year was his first major championship since the 2015 U.S. Open.

The 24-year-old Kamiji, the world's top-ranked women's player and top seed, defeated second-seeded Diede de Groot of the Netherlands 2-6, 6-0, 6-2.

"I swung the racket well," Kamiji said. "I had the sensation of my concentration level rising. I have now won two straight titles here, but I wasn't focused on doing that."

Kamiji, who won three Grand Slams in 2017, lost this year's Australian Open, when she fell to de Groot in two sets.
