Mark Allen delights home crowd with comfortable win over Chen Zifan in the Northern Ireland Open

Allen delighted the crowd at Belfast's Waterfront Hall as he opened up with a break of 102 on his way to a confident 4-0 win, which saw him finish with runs of 85, 92 and 50.

Next for Allen will be Hong Kong's Andy Lee, who edged out Dylan Emery 4-3, while former world champion Neil Robertson had earlier defeated Fan Zhengyi 4-2 to take his place in the last 32.

Mark Selby made three half-century breaks as he recorded his own 4-2 win over Sam Craigie, and Scotland's Stephen Maguire needed a final-frame decider as he came from 2-0 down to see off Zak Surety.

In Monday's late evening matches, Mark Williams made a 139 clearance in the second frame as he defeated Swiss player Alexander Ursenbacher 4-2. The veteran Welshman will go on to meet Jimmy Robertson, who chalked up two half-century breaks in his 4-1 win over Andy Hicks.

Earlier, John Higgins beat Ireland's Fergal O'Brien 4-2 in a first-round match, but Jack Lisowski is out after losing by the same scoreline to Li Hang.
