Ronnie O'Sullivan has opened up a 10-6 lead over Luca Brecel in their World Championship quarter-final.
The 47-year-old is bidding to win a record-breaking eighth title, and he will be delighted to hold a four-frame advantage over his Belgian opponent.
Brecel came out of the gate with a 93 break but after being pegged back for 2-2, he watched O'Sullivan surge into a 6-2 lead by the end of the opening session.
That was despite O'Sullivan almost gifting him the seventh frame when his waistcoat made contact with the black, resulting in a seven-point penalty, only for Brecel to miss a frame-clinching pink after a poor set-up shot.
Upon their return in the evening, Brecel produced a majestic 128 and momentum was growing as he got back to 7-4 and 8-6 during different stages of the second session.
However, O'Sullivan took the final two frames to establish a 10-6 advantage ahead of returning tomorrow afternoon.
Selby and McGill will be the happier of the two players, each of them facing three-frame deficits at one point before hauling themselves back level.
