“I think it's so good that all of the Grand Slams are supporting this, and I think it will definitely help raise the level of wheelchair tennis,” she said.
“Hopefully it doesn't take too long for all of those good players on the bottom of the draw to keep up.”
Having posted her 100th successive win in defeating Emmanuelle Morch in the first round, the Dutch star described this year’s edition of Roland-Garros as special.
'A really, really tough opponent'
The early stages of the final were tight as Kamiji, a four-time champion at Roland-Garros, showed her fondness for clay in a bright opening against the 18-time major champion.
De Groot, now a four-time title winner in Paris who is halfway to completing her third straight Grand Slam, swung the momentum her way after a struggle in her second service game.
Kamiji fought valiantly but said her rival was too strong.
“You are such a great player. A really, really tough opponent,” Kamiji said.
Kamiji was able to exact a measure of revenge when partnering Kgothatso Montjane to a 6-2, 6-3 triumph over De Groot and Maria Florencia Moreno in the women’s wheelchair doubles final.
