Northern Ireland golfers Cormac Sharvin and Chris Selfridge are through to the last 32 of the matchplay knockout stage of the British Amateur Championship.
Moyola Park man Selfridge, the reigning North of Ireland Amateur champion, beat David Boote of Wales 4&3 and will now play England's Toby Tree on Friday.
Ardglass player Sharvin saw off Scotland's Calum Hill 2&1 and now faces Victor Fasmer Henum from Denmark.
The tournament will continue at Royal Portrush until Sunday.
The event had been scheduled to finish on Saturday but the Royal and Ancient were forced to reschedule the programme because heavy fog heavily curtailed play on Tuesday.
Leading qualifier Daniel Brown, from Bedale in Yorkshire, defeated American Myles Lewis 2&1 in his last 64 match on Thursday.
Brown finished four shots ahead of fellow Englishman Ashton Turner and Italian Renato Paratore in the two-day qualifying.
Seven Northern Ireland competitors teed up on Monday, with Sharvin and Selfridge the only two to progress to the matchplay stage.
The 119th playing of the tournament has attracted an international field, including players from as far afield as South America and New Zealand.
The 16 second-round matches and eight third-round ties will be staged on Friday, with the quarter-finals and semi-finals on Saturday and the 36-hole final on Sunday.
