The Tournament of Champions, currently titled as The Sentry, is the calendar-year opening tournament of golf's PGA Tour season, played in Hawaii on the island of Maui. The tournament was founded in 1953; for most of its history the field was restricted to golfers who won a tournament on the tour during the previous calendar year, but players who qualified for the preceding Tour Championship are now invited as well.
