The betting markets have Scottie Scheffler as the favorite to win the Open Championship at Royal Troon, but the decision isn't cut and dry. While Scheffler leads in important stats like strokes gained and greens in regulation, his lack of recent play and past major performance raise doubts. Players like Rory McIlroy, who bounces back quickly from setbacks and excels in driving ability, could pose a challenge. History favors Scheffler, but the unpredictable elements of Troon, like pot bunkers and gusty winds, could work against him. As other top contenders, such as Collin Morikawa, Viktor Hovland, and Ludvig Åberg, also have momentum and strong setups for the course, the competition is fierce. Ultimately, while Scheffler remains a top contender, McIlroy emerges as a compelling choice to challenge for the Claret Jug.
