Oliver Lines emerged from a match against his father Peter with a 2-0 victory in their Group J WST Pro Series match at the Marshall Arena in Milton Keynes.
World number 103 Oliver constructed runs of 67 and 74 to beat father Peter in Milton Keynes to make it five wins from five at the WST Pro Series.
However, Lines Jr. would lose his perfect record against Ian Burns - going down 2-0 - but would beat Elliot Slessor by the same score, making a 77 in the second frame, in his final match on Tuesday to ensure the 25-year-old cueist’s progression to the second group stage. James Cahill, who shocked Ronnie O'Sullivan in the first round at the 2019 World Championship, finished second after beating Iulian Boiko in his final match.

The match represented the first time a father and son had faced each other at a ranking event since Neal beat Geoff Foulds 5-0 at the International Open in 1986. The Foulds also faced one another in a non-ranking event – the English Professional Open, also in 1986 – with Neal winning that encounter 9-4.
