The WM Phoenix Open, formerly known as the Waste Management Phoenix Open, is one of the most popular and highest-attended tournaments on the PGA TOUR. Held annually at TPC Scottsdale, the event is famous for its energetic atmosphere, especially at the iconic par-3 16th hole, often called the loudest hole in golf. The tournament combines world-class competition with large-scale hospitality, concerts, and charitable fundraising, making it one of the most distinctive events in professional golf.
