The USGA: The United States Golf Association has served as the sport’s national governing body since 1894. More than 9,000 private and public courses comprise the USGA, which conducts 13 national championships, the majority of which are amateur events other than the PGA Tour U.S. Open, Champions Tour U.S. Senior Open and the women’s U.S. Open.
Defending champion: Kenny Perry. In the 2013 event, Perry fired a final round 7-under par 63 to come from one stroke back to finish with a 13-under 267, five shots better than runner-up Fred Funk at Omaha Country Club.
Multiple U.S. Senior Open champions: Miller Barber (1982, 1984 and 1985) is the only three-time U.S. Senior Open winner. Four players have won twice — Gary Player (1987, 1988), Jack Nicklaus (1991, 1993), Hale Irwin (1998, 2000) and Allen Doyle (2005, 2006).
Oldest winner: Doyle turned 58 a few weeks before winning in 2006.
Youngest winner: Dale Douglas won in 1986 four months after his 50th birthday.
2014 tournament facts
The field: Including 76 spots earned at one-day qualifying tournaments at 34 sites around the country, a field of 156 golfers will be trimmed to the lowest 60 scores, plus ties, after the first two rounds.
The purse: The prize pool will be around $2.7 million with the winner earning $500,000.
Playoff tiebreakers: If there is a tie after 72 holes, all players tied will play a three-hole aggregate playoff on Sunday.
Oak Tree National
The course: Known for its small greens, Oak Tree National is one of the hardest golf courses in the United States. It wouldn’t be shocking if someone shoots in the 90s the first two days and only a handful of players shoot under par over four days on the 7,219-yard, par-71 layout.
Oak Tree’s three majors
1984 U.S. amateur: An All-American at Oklahoma State, future Oak Tree member Scott Verplank won the U.S. Amateur. Seven additional players in the U.S. Senior Open field (Billy Andrade, Mike Goodes, Jeff Maggert, Michael McCoy, Rocco Mediate, Kirk Triplett and Dusty Waldorf) played in the 1984 amateur.
1988 PGA: Jeff Sluman won the 1988 PGA Championship by three shots over Paul Azinger after firing a 6-under-par 65 on Sunday to finish 12-under.
2006 Senior PGA: Bill Haas won in a playoff to capture the Senior PGA Championship, finishing 5-under for the tournament.
