John Higgins created his own slice of snooker history by becoming the first player to compile a maximum break in successive matches at Brighton today.
Higgins, who knocked in a 147 during the LG Cup final at Preston last month, made another en route to beating Michael Judge 5-1 in the second round of the British Open.
It earns the world number four a £20,000 cash bonus plus £5,000 for the highest TV break.
The Scot said afterwards: "I've had quite a few 147s in practice before I came down here so I knew I was playing well.
"I never used to play for maximums but just lately they've been going in quite regularly.
"It's like waiting for a bus. You wait for ages and then a load come at once, so I'm over the moon."
The perfect break was the fourth 147 of the Wishaw star's career. He had not even made one in practice until after becoming world champion in 1998 and his first in a tournament came at the 2000 Nations Cup.
He followed that up two months later by constructing another maximum in the Irish Masters.
Higgins became only the second player, after Hendry, to record a 147 in a major final against Williams, but he was beaten 9-5.
Only Stephen Hendry, with eight, and Ronnie O'Sullivan, with six, have made more maximums.
It was the 48th maximum in professional snooker history, the 27th in a world ranking event and 24th to be made on television.
Higgins continued: "With the likes of Stephen and Ronnie in the tournament, they could equal it.
"But the good thing is that I'm feeling a lot happier with my game, and that comes through by making decent breaks.
"I'm a lot more settled - so long may it continue."
Judge had set the high TV break target with his 138 in the previous frame but it stood for only 12 minutes.
The Dubliner said: "John played brilliantly, as he proved with his maximum - at least my break got beaten by a 147."
Higgins, who won the British Open two years ago - the last ranking event he was successful in - meets world number 35 Mark Davis for a place in the quarter-finals.
