Defending champion Mark Selby is through to the Masters semi-finals after a thrilling 6-5 win against John Higgins at Alexandra Palace in London.
Selby, the number one seed, took an early 3-1 lead before the Scotsman won four consecutive frames to go 5-3 up.
But Selby, 30, fought back to 5-5 before winning a tense deciding frame.
In the last four, Selby will meet fellow Englishman Shaun Murphy, who came from three frames down to beat Marco Fu 6-4.
