Arizona Open

The Arizona Open Championship is the annual open state championship of golf in Arizona. The competition is 54-holes of stroke play (3 rounds on an 18-hole course), with the winner being the player with the lowest total number of strokes. Following 36-holes of play the field is cut to the top 50 players and ties for the final round. In the event of a tie following 54-holes, a hole-by-hole, sudden death playoff will determine the winner. The Championship is administered by the Southwest PGA (Professional Golfers' Association of America). The Arizona Open has roots dating back to the inaugural event held in 1937. This historical championship has been held annually since 1953 and boasts an impressive list of past champions including Johnny Bulla, Dale Douglas and Curt Byrum.

Qualification
The Arizona Open Championship is open to any professional golfer or to any amateur golfer with a USGA Handicap Index not exceeding 10.0. Players (male or female) may obtain a place in the Championship proper by being fully exempt or by competing successfully in qualifying. Approximately 1/3 of the field is made up of players who are fully exempt from qualifying. Competitors who are not fully exempt must register and compete in a qualifier. Place-winners from qualifying events, conducted historically throughout the month of July, along with those players exempt from qualifying, finalize the Championship field of 156 competitors.
