The 1973 Open Championship was the 102nd Open Championship, played 11–14 July at Troon Golf Club in Troon, Scotland. Tom Weiskopf won his only major championship by three strokes over runners-up Neil Coles and Johnny Miller, the winner of the U.S. Open a month earlier. Weiskopf was a wire-to-wire winner and his four-round total of 12-under-par 276 matched the then-existing Open Championship record set by Arnold Palmer on the same course in 1962. Gene Sarazen, 71, made a hole-in-one in the first round at the famous 8th hole, a 126 yd par-3 named the "Postage Stamp," due to its small green. Lee Trevino's bid for a third straight Open fell short, thirteen strokes back in a tie for tenth place. This was the course's last Open Championship under the name Troon Golf Club; it became Royal Troon Golf Club five years later in 1978, and next hosted in 1982.
