Oliver Lines beat his dad Peter Lines 2-0 on his way to topping Group J at the WST Pro Series event in Milton Keynes, but admitted he would rather have not contested the historic match.
It was the first time a father and son had contested a ranking event since Eurosport pundit Neal Foulds whitewashed dad Geoff 5-0 at the International Open in 1986.

"The game against my dad was one of the worst I've been involved in," said 25-year-old Leeds-born Oliver, who constructed runs of 67 and 74 against dad Peter, 26 years his senior.
“Usually, you want to keep your opponent in his seat because that means you are winning.
But against my dad, every ball I potted, it felt wrong, I felt bad. There is no one I ever want to win more than my dad. It was a massive struggle, and he struggled as well. It was one to forget.
World number 103 Lines won six of his seven matches to top the group on 18 points alongside James Cahill, who reached the last 32 in second place having lost three frames more. He also recorded a 120 break in a 2-0 win over Ukraine teenager Iulian Boiko.
The second group stage of the WST Pro Series begins on Wednesday 17 March with 32 qualifiers from 16 groups making up four more groups of eight.
The final group will be contested between the top two from each group on Sunday 21 March, the day before the Tour Championship begins.
