Thailand's Thepchaiya Un-Nooh missed the final black of a 147 attempt for the second time this season during World Championship qualifying.
The world number 35 rattled the jaw of the pocket against Anthony McGill in the fourth frame of their final qualifying round to level at 2-2.
The miss cost him an £8,500 bonus, plus the £1,000 highest break prize.
He also missed the black on 140 against Neil Robertson in the third round of the UK Championship in December.
The 30-year-old later claimed he did not know that there was a £44,000 prize for a maximum.
Un-Nooh, who has never qualified for the World Championship, currently trails Scotland's McGill 6-3 at the interval.
The final qualifying round continues on Wednesday.
