Ding Junhui has compiled a 147 break in his quarter-final contest with Neil Robertson in the Welsh Open.
The Chinese former champion trailed the Australian 4-1 at the time but the break looked on from an early stage with the reds all in the middle of the table.
Ding found himself in difficult situations on several occasions throughout the superb run, in particular on the final colours as the drama intensified.
But the 28 year-old kept his cool to clear the table for a magnificent sixth maximum break of his career – only Ronnie O’Sullivan, Stephen Hendry and John Higgins have made more.
It’s the 117th in professional play and, assuming it isn’t equalled this week, will be worth a tidy £12,000 to the former world no.1.
Of course, O’Sullivan himself was on course to make the perfect frame on Monday only to controversially take a pink with the penultimate red in an apparent protest at the prize on offer.
Ding went on to lose to Robertson 5-2, with the Australian moving into the last four.
