U.S. Open

The United States Open Championship, commonly known as the U.S. Open, is the annual open golf tournament of the United States. It is the second of the four major championships in golf and is on the official schedule of both the PGA Tour and the European Tour. It is staged by the United States Golf Association (USGA) in mid-June, scheduled so that, if there are no weather delays, the final round is played on the third Sunday, which is Father's Day. From 2008, it will also be an official money event on the Asian Tour, with 50% of Asian Tour members' earnings counting towards the Order of Merit.

The U.S. Open is the only one of the four major championships which does not go immediately to a playoff if two or more players are tied at the end of the four rounds. Instead, the players play a fifth 18-hole round the following day (Monday), but if a tie still exists after the round, then a sudden death playoff is held. Only three times has the U.S. Open gone to sudden death after the playoff round, most recently in 2008 when Tiger Woods defeated Rocco Mediate on the first playoff hole.

Coverage of The U.S. Open is broadcast on television by NBC and ESPN, with additional online coverage of a marquee group provided by ESPN via the U.S. Open's official website. Of golf's broadcast television partners in the U.S., NBC is the only one to provide four days of major tournament coverage (CBS, which airs the Masters and the PGA Championship, only provides weekend coverage of its tournaments; starting in 2010, the British Open will not be aired on an over-the-air network at all, with all four rounds airing on ESPN).
