PALM BEACH GARDENS, Fla. — The U.S. Open is changing to a two-hole aggregate playoff, the last of the four majors to do away with an 18-hole playoff.

The change is takes effect immediately and would be used at Shinnecock Hills on Long Island in June if there is a tie after 72 holes. The U.S. Golf Association also decided to make its other three open champions two-hole playoffs — the U.S. Women’s Open, U.S. Senior Open and U.S. Senior Women’s Open.

The U.S Open has had 33 playoffs in its 117 years, all decided by 18 holes or more.

“There was a time when they did make sense before television, before the modern era of wanting everything decided immediately,” said Mike Davis, chief executive of the USGA. “There is no correct way to determine a tie in stroke play.”

The last U.S. Open playoff was 10 years ago at Torrey Pines, where Tiger Woods beat Rocco Mediate in 19 holes for his 14th major.

The Masters was the first major to abandon the 18-hole playoff in 1976 when it changed to sudden death. The PGA Championship did the same a year later, and Lanny Wadkins won the first sudden-death playoff in major championship history in 1977 at Pebble Beach. The PGA later changed to a three-hole aggregate.

The British Open changed to a four-hole aggregate in 1986.

The U.S. Open used to have a 36-hole playoff, last used in 1931.
