Shaun Murphy rallied from 4-2 down to record a 6-4 victory over Ding Junhui, while Ronnie O'Sullivan raced to a 6-1 win against Robert Milkins on Tuesday at the Masters.
Former world champion Murphy set up a clash with Marco Fu by taking four frames in a row to decide a see-saw afternoon clash that saw neither man manage a century.
Ding recorded the highest break of the match when he knock in 99 in the opening frame once play finally got underway after an 80-minute delay due to a power-cut at Alexandra Palace.
