Roberto DeVicenzo (Born April 14, 1923) -- Perhaps the archetypal international golfer of the 1950s, he won an astonishing 230 tournaments worldwide in his career, including four on the PGA Tour and the 1967 British Open. The Argentine-born golfer is best remembered for his misfortune in the 1968 Masters, where he signed his scorecard for a score higher than his actual score on the 17th hole, signing for a par 4 when actually made a birdie 3. Under the Rules of Golf, the higher score stands once a player has signed his card. If not for this mistake, DeVicenzo would have tied for first place with Bob Goalby, and the two would have met in an 18-hole playoff the next day. DeVicenzo subsequently found great success in the early days of the Senior PGA Tour, winning the Liberty Mutual Legends of Golf three times and the inaugural U.S. Senior Open in 1980. Also won the 1974 PGA Seniors Championship, and represented Argentina 17 times in the Canada Cup and World Cup (leading Argentina to victory in 1953).
