Two-time runner-up Ali Carter took advantage of an error-strewn display from Jack Lisowski to advance to the second round of the World Championship in Sheffield.
Carter had to come through qualifying to make his 17th consecutive appearance at the Crucible, but eased to a 10-6 victory over 11th seed Lisowski to set up a last-16 clash with China's Zhou Yuelong.
The 39-year-old from Essex held a 5-4 lead overnight and took the first two frames of the day before a fluked red set up a break of 73 and took him into an 8-4 lead.
Lisowski looked like reducing his deficit in the 13th frame, only to miss a simple brown into the yellow pocket, and Carter cleared up to move within one frame of victory.
Carter handed Lisowski a lifeline when he missed the black to seal victory in the next frame and Lisowski took advantage of his reprieve in style with a total clearance of 124 in frame 15, but a break of 46 in the next helped Carter seal a fully-deserved win.

On the other table, Neil Robertson claimed a 5-3 lead over fellow former champion Shaun Murphy after the first session of their second-round encounter.
Murphy failed to pot a ball in the first three frames but fought back to win two of the last three frames and could have compiled a maximum break in the last frame of the session.
After potting 13 reds and 13 blacks Murphy even paused to ask for the screen separating the tables to be lifted but went on to miss a tough final red into the middle pocket.
Robertson had earlier compiled breaks of 106, 79, 57 and 127 in a high-quality encounter between two players who had lost just one frame between them in the first round
The final session of the evening ended with Gary Wilson taking a 5-3 lead over Mark Selby.
