The Open Championship, often referred to as The Open or the British Open, is the oldest of the four major championships in professional golf. Held in the United Kingdom, it is administered by The R&A and is the only major outside the United States. The Open is currently the third major of the year, between the U.S. Open and the PGA Championship, and is played in mid-July.
The current champion is Henrik Stenson, who won the 145th Open at Royal Troon in 2016 with a record-breaking score of −20. Wikipedia
