Two-time Australian Open winner Kamiji beat the same Dutch opponent in the semi-finals of the women's singles tournament at the Paralympics.

Van Koot gained a measure of revenge on court eight at Melbourne Park today.

Van Koot won both sets 7-5 to book her place in the semi-finals, where she will face Kgothatso Montjane of South Africa after her three-set victory over Jiske Griffioen of The Netherlands.

Dutch defending champion Diede de Groot, the Tokyo 2020 singles and doubles gold medallist, was on Kia Arena where she eased into the semi-finals by beating the United States' Dana Mathewson 6-2, 6-1.

She will face British wildcard Lucy Shuker for a place in the final after her 6-2, 6-2 win against China's Zhu Zhenzhen.

In the men's singles, 10-time winner and three-time Paralympic singles champion Shingo Kunieda of Japan saw off Belgium's Joachim Gérard 6-4, 6-2, with last year's runner-up Alfie Hewett of Britain overcoming Argentina's Gustavo Fernández 6-1, 7-6.

Top seed Kunieda will face The Netherlands' Tokyo 2020 silver medallist Tom Egberink in the semi-finals.

Egberink won both sets against Australia's Ben Weekes 6-1, while France's Stéphane Houdet - a five-time Australian Open runner-up - beat Britain's former Paralympic champion Gordon Reid 6-4, 6-1.

Home favourite Dylan Alcott will retire after the Australian Open, having clinched the Golden Slam with all four majors and the Paralympic title last year, and he was in action on Kia Arena in the quad singles event.

Alcott had to come from behind against Dutch Tokyo 2020 singles bronze medallist Niels Vink, but triumphed 6-7, 6-4, 6-2 in their quarter-final.

Andy Lapthorne of Britain stands in Alcott's way of a place in the final after he beat South African wildcard Donald Ramphadi 7-5, 6-3.

Second seed Sam Schröder, the Tokyo 2020 silver medallist and another Dutchman, beat American David Wagner 6-1, 6-3.

He will face an Australian player in the semi-finals after Heath Davidson won 6-2, 6-2 against Japan's Koji Sugeno.
