For bettors hunting a bomb, MacMillan highlighted Aaron Rai at 120-1 outright or +260 for a top-20. Rai ranks second on the PGA Tour in driving accuracy and 25th in greens-in-regulation, traits MacMillan says become even more valuable if Portrush turns blustery. While Rai’s recent finishes (T19 PGA, T17 Travelers) won’t wow casual bettors, MacMillan likes his history of excelling in poor weather, including victory at the 2020 Scottish Open. Because distance is less critical on this links layout, Rai’s precision could translate into a surprise leaderboard run, making him a cheap lottery ticket with solid positional betting options.
