Luke Humphrez resisted to demand a victory of 10-7 and end the date of making the Brves's history in the UK Open.
Greaves in the first ladies world became the first player to reach the fourth round of the tournament by beating Stephen Belont, Ris Griffin and Mickey Mansil earlier on Friday.
Then he led the 21-year-old 7-5 against the first world ranking for men, but Humphrez won five consecutive legs to secure his place in the past 16.
“She belongs to the big arrows,” Humphrez told ITV4.
“She belongs to this environment. You really tested me there, and if we are in a Premier League match, it will defeat me.”
Griffs, the ladies world champion, opened three times, with 126 exit before 124 came out to break the progress 2-0.
But Humphrez was on his way back, and after his victory, Griffs called for the theater and the couple bended in front of the crowd at the Potternin Minhid Resort.
“To play Luke, he is amazing, and for me and my game, you will bring me in a long run,” Graves, who has average 93.60 to Humphrez 103.40.
“I am watching these types of players all the time on Tele, so it's good to be here. Frankly, I enjoyed watching him while throwing.”
Earlier on Friday, Johnny Clayton defeated Gary Anderson 10-3 before Men's world champion Luke Litler Peter Wright has skipped.
The teenager Littler 7-4 and 9-7 pursued that Wright was late to move on 9-9.
Facing an opportunity to end victory with 170 exit, Littler is shown after following the first safety approach and shooting 10 beds.
The 18 -year -old shook his finger and mouth “not an opportunity” for the crowd before he eventually won average of 108.69.
Michael van Gereen, the hero of three times, defeated his Dutchm by Dirk Van Dujvhvod 10-8, while Gerawin Price lost 10-9 in front of Conor Scott.
