The BMW Championship serves as the final opportunity for players to secure automatic spots for the upcoming Presidents Cup, with significant implications for American and Canadian golfers. Jordan Spieth's season has ended after he failed to advance in the FedEx Cup and announced he would undergo wrist surgery. This setback impacts Mackenzie Hughes, who has dropped out of the top 50, as International captain Mike Weir aims to include a strong Canadian presence on the team. Currently, the top five players for the U.S. team are Scottie Scheffler, Xander Schauffele, Collin Morikawa, Wyndham Clark, and Patrick Cantlay, with Sahith Theegala holding the sixth spot. Notably, players like Max Homa and Justin Thomas face pressure to perform after disappointing recent showings. The upcoming Tour Championship will allow Weir to make six captain's picks, shaping the final roster.
