Neil Robertson completed an unprecedented eighth 6-2 win in the first round of the Masters as he advanced past Chris Wakelin into the quarter-finals.
Wu Yize started the sequence when he defeated defending champion Shaun Murphy on Sunday at Alexandra Palace.
World number one Judd Trump progressed past Ding Junhui on Wednesday afternoon for the first round's seventh consecutive 6-2 scoreline - at odds of 44,000-1.
But there was more to come, with Robertson completing a 6-2 clean sweep in the evening - and the odds of all eight opening-round matches finishing that way were 220,000-1.
Remarkably, the odds of predicting the scores and also correctly naming all eight winners amounted to 20,000,000-1.
No more than four first-round contests had previously ended 6-2 at any Masters tournament, but when two-time winner Robertson made superb back-to-back century breaks after the interval to establish a 4-2 advantage, a clean sweep appeared inevitable.
Wakelin, making only his second appearance at the Masters, as a last-minute replacement for record eight-time champion Ronnie O'Sullivan, was unable to arrest the trend.
"I wasn't even thinking about winning the match - I was thinking just win it 6-2," joked Robertson on BBC Four
