World number one Esther Vergeer captured her 12th British Open wheelchair tennis title by beating Dutch compatriot Aniek van Koot.
Vergeer won 6-2 6-0 in Nottingham to extend her unbeaten run to 465 matches.
British number one Gordon Reid overcame Dutch world number four Ronald Vink 6-3 6-2 to reach Sunday's men's singles final - his first Super Series final.
However, Britain's Jamie Burdekin was beaten by Israel's Noam Gershony in the men's quad singles final.
Reid, 20, had never reached a Super Series semi-final before beating Joachim Gerard on Thursday, but now faces Japan's Shingo Kunieda in Sunday's final.
"I am so happy with that result, I've only ever beaten Ronald once before in 11 attempts and I knew I could do it again, but to do it here was fantastic and just ahead of the Paralympics too," said Reid.
Burdekin went down 6-3 6-2 to Gershony, ranked number three in the world.
"I'm obviously disappointed to lose but Noam was the better player and he deserved the win," admitted Burdekin.
"I now have six more weeks to prepare before the Paralympic Games and there is more work to be done."
However, Burdekin and Andy Lapthorne did overcome Anders Hard and Lucas Sithole 6-1 7-6 (7-5) to reach Sunday's quad doubles final.
