The Holywood man shot a two-under 69 in Friday’s second round to secure an afternoon tee time on Saturday as he put himself in a share of 12th, seven shots behind overnight leader Scottie Scheffler.
World No.1 Scheffler leads the way at 10-under-par after a dazzling second round 64 and he will be the last man on the course at 3:35pm, with England’s Matthew Fitzpatrick his playing partner one shot behind him at nine-under-par.
Offaly’s Shane Lowry, who took a controversial penalty in his second round, will get his third round under way at 11:30am as he is in a blockbuster early group with Spain’s Jon Rahm, while the enigmatic Bryson DeChambeau is due on the first tee at 10:25am where he will be accompanied by England’s Nathan Kimsey.
Germany’s Matti Schmid, who has Castledawson man Chris Selfridge on his bag, will get the action under way at 9:35am when he tees off alongside Corey Conners in the opening group.
The tee times have been moved forward by 15 minutes in order to avoid clashing with a loyalist band parade in Portrush town centre, which is due to begin at 8:30pm and will feature over 70 bands.
