John Higgins and Stephen Maguire will contest a battle of the Scots in 16 of the Lisbon Open after winning their opening three matches in Portugal.
Higgins has shown a little bit of a return to form in the last few weeks after a long time struggling with his game.
The 39 year-old fired in a brace of centuries in his 4-1 victory over Jimmy Robertson on Saturday and overcame Allan Taylor by the same scoreline to reach the fourth round.
Maguire was also in high-scoring mood when, after a tight 4-3 win over Sanderson Lam, the Six Red world champion compiled 110 and 102 centuries against Finland’s Robin Hull before a 4-0 rout of Barry Pinches.
Meanwhile, Stuart Bingham bounced back from the disappointment of his narrow semi-final defeat to Ronnie O’Sullivan at last week’s UK Championship to set up a clash with Craig Steadman today.
Steadman caused the biggest upset of the tournament when he ousted Shaun Murphy, victorious in the last two European Tour events, 4-1 in the first round.
Elsewhere, Norway’s Kurt Maflin registered his 100th career competitive century in a 4-0 triumph over Gary Wilson and he subsequently came from 3-1 down to pip Rod Lawler in a decider.
Maflin will play Noppon Saengkham for a quarter-final place after the Thai required all seven frames as well in his successes over David Grace and Mitchell Mann.
Finally, talented 20 year-old Joel Walker beat rival up-and-coming star Oliver Lines 4-1 to set up a clash with another Englishman, Mark Davis.
The fifth European Tour event of the campaign comes to a conclusion on Sunday with €25,000 up for grabs for the champion.
