On April 14th 1923, Roberto de Vicenzo (left) was born in Buenos Aires. From golfing beginnings as a lagunero or pond boy, he developed into one of the finest players in the history of the game. In 1967, at 44 years and 93 days, he became the oldest British Open winner of modern times, capturing the trophy at Hoylake. And a year later, on his 45th birthday, he was deprived of a play-off place in the US Masters when he signed for a score, one stroke higher than he had shot on the 71st, through an error by his playing partner, Tommy Aaron. So, he had to settle for second prize of $15,000 along with a pair of goblets as a reward for an eagle at the par-four first hole in his final round.

Teaser: An old hole plug is raised on the player's line of putt. The player steps on the hole plug to make it level with the surface of the putting green. In so doing he pressed down a spike mark within the plug hole. Was the player in breach of Rule 16-1a when he pressed down the spike mark.

Answer: No. Rule 16-1a permits touching the line of putt "in repairing old hole plugs." If the spike mark had been near but not within the old plug hole, the ruling would have been different. In these circumstances, the player would have been able to step on the hole plug without affecting the spike mark.
