Lisa Ashton became the first woman to win at the UK Open since 2005 when she beat Aaron Beeney in the second round and made history in doing so.
The 50-year-old downed Beeney 6-2 to become the first female to win at this tournament since Dena Hedman 16 years ago.
Ashton, who is the first woman to hold a PDC Tour card, did it in style as her staggering average of 100.3 is a new world record for a woman in a televised match.
However, her fun ended in the next round, losing 6-2 to Darius Labanauskas but it was still a day to remember.
Brown claims there was no space to sit down in the practice room so he made his way back to his hotel room at the other end of the complex in Milton Keynes to relax before his match.
He started watching other matches on television and lost track of time, before seeing Waites warming up on stage on his screen.
A mad dash across the venue was in vain as he was timed out and thrown out of the competition.
Raymond Van Barneveld’s return to the tour ended in disappointment.
The Dutchman, a two-time winner of the UK Open, was playing in his first televised event since coming out of retirement but was beaten 6-3 by Alan Soutar in the second round.
In the evening session, defending champion Michael Van Gerwen won his fourth-round match against Scott Mitchell 10-8.
Last year’s runner-up Gerwyn Price, the PDC world champion, also advanced as he recorded a comfortable 10-5 victory over Peter Hudson.
But Peter Wright, Gary Anderson and Nathan Aspinall, the title winners of 2017, 2018 and 2019 respectively, all exited.
Wright lost 10-5 to Dave Chisnall, Anderson was edged out 10-9 by Dirk Van Duijvenbode and Aspinall was beaten 10-5 by Krzysztof Ratajski.
