Defending champion Shingo Kunieda ended Nyasha Mharakurwa's dream of winning Africa's first medal in Wheelchair Tennis at Eton Manor yesterday.
The Zimbabwean fell to a 6-0 6-0 defeat in a second-round match that took just 36 minutes.
Mharakurwa said afterwards, "I feel good. I played calmly and I gave him a bit of trouble. The difference is he makes every ball count.
"He's still trying after two, three balls and he doesn't give you a chance to wind it up. He doesn't give you a chance in the end. He takes control."
Elsewhere in the men's competition, another Japanese player, five-time Paralympian Satoshi Saida, suffered a surprise defeat to rookie Adam Kellerman of Australia as he went down 6-3 6-2.
