World champion Kyren Wilson edged past Zhang Anda 6-4 to move into the quarter-finals of the Masters at Alexandra Palace.
Wilson remarkably finished the contest having potted significantly fewer balls, and scoring 275 points less than Zhang, but was crucially clinical when it mattered – taking the first, fourth and seventh frames when his opponent was well-placed to win them.
The Englishman, who has already won two events this term, led 3-1 at the interval but Zhang compiled breaks of 65, 83 and a sublime 141 to leave the match delicately poised at 4-4.
However, Wilson then took a nervy frame and sealed his victory in a tense 10th frame.
“I feel like I managed to pinch the key frames,” Wilson told BBC Sport.
“Every credit to Zhang, I thought he played fantastic. I have never seen such a consistent display of long potting.
“I was petrified every time a ball stuck out because he was just potting them. It was incredible. I just had to hang on in there and nick the odd frame. I am pleased to just get over the line.”
Wilson will now face Luca Brecel or Chris Wakelin, who play the final first-round match on Wednesday (19:00 GMT).
