Defending champion Judd Trump hit his fifth career maximum break at the Northern Ireland Open on Wednesday.
The world number one made the 147 clearance in the third frame of a 4-0 victory over 16-year-old Gao Yang in the second round in Milton Keynes.
It was a brilliant performance from Trump, who hit two other century breaks during the match.
The 31-year-old first achieved the feat in 2013 while his most recent maximum prior to this event came at the German Masters in 2018.
The Northern Ireland Open was moved to England because of coronavirus restrictions.
