Ronnie O’Sullivan remained on track for a Players Tour Championship double as he reached the last 16 of PTC 2 at the South West Snooker Academy in Gloucester.
The former world number one, who claimed the first PTC event of the new season in June, endured the tougher side of the draw to book a meeting with young talent Laim Highfield in round four.
O’Sullivan has been a frequent opponent of the strict dress code for the tournament this week – insisting that there should be a less formal requirement for the smaller events – but still performed to a pretty high standard in his opening three contests.
After disposing of amateur Nick Jennings, the three-time world champion dislodged old rival Stephen Hendry 4-1 before pipping Welshman Matthew Stevens in a decider.
The pick of the Last 16 ties is arguably between Neil Robertson and Judd Trump in a repeat of their first round clash at The Crucible in April.
Trump won his first matches of the season with a 4-2 triumph over Mark Allen of Antrim the highlight.
Fergal O’Brien staged a remarkable comeback to oust ‘Tornado’ Tony Drago, the Irishman winning the last four frames for a 4-3 victory.
The Dubliner has recently qualified for the Shanghai Masters next month and continued the good form with earlier wins over Billy Joe Castle and Passakorn Suwannawat.
O’Brien will meet Ali Carter for a place in the quarter-finals after the Englishman maintained John Higgins’ inconspicuous start to the season with a 4-1 defeat of the world champion.
Inexperienced duo Adam Duffy and China’s Yu Delu contest the remaining round four match with the former shocking fellow Englishman Mark Selby 4-0 in the last 32.
