Defending champion Judd Trump made a 147 clearance in his second-round win over Gao Yang at the Northern Ireland Open this afternoon.
Trump made the break in the third frame of a 4-0 victory over the 16-year-old Chinese player in Milton Keynes.
The event has been moved to England due to Covid-19 protocols.
Trump was in sparkling form, making two more centuries in the match.
The 31-year-old made a 127 contribution in the first, before the 147 in the third and concluded the victory with a 109 break.
The maximum break was the fifth of the 2019 world champion's career. He first achieved the feat in 2013 while his most recent maximum prior to this event came at the German Masters in 2018.
Trump, who has beaten Ronnie O'Sullivan in the final for the last two years, will take on Belgian Luca Brecel in the third round.
Ireland's Ken Doherty and Fergal O'Brien saw their tournaments draw to a close in contrasting fashion.
Kyren Wilson opened with a break of 95 against the 1997 world champion and raced to a 3-0 lead, but Doherty fought back to level the match at 3-3 and force a deciding frame, recording breaks of 90 and 71 in the process.
However, Wilson proved faultless in the final frame and a break of 135 saw him progress to the third round.
O'Brien proved no match for Thepchaiya Un-Nooh, with the Thai potter knocking in contributions of 94, 84, 61 and 60 in an authoritative 4-1 victory.
World champion O'Sullivan came from behind to progress with a 4-1 win over Elliot Slessor.
O’Sullivan had lost his two previous meetings against the world number 56 and was again on the back foot as Slessor opened with a break of 71.
It might have got worse but Slessor missed a crucial red in the second frame and O’Sullivan hit back before easing to victory with breaks of 76, 78 and 97.
O’Sullivan, who will now play Matthew Stevens, told Eurosport: "That’s up there with one of the best victories of my career. He beat me twice before. He had the voodoo sign over me and seems to play fantastically well every time he plays me.
"The way he started off I thought, 'here we go again’. I just had to hopefully get a chance.
"Sometimes beating someone like Elliot Slesser in this tournament, in that round, is better than beating someone like (Mark) Selby in the semis of the worlds. Everyone on the circuit knows how good Elliot is. He can play."
