English golfer Simon Dyson was sensationally disqualified from the BMW Masters in Shanghai yesterday before teeing off his third round.
He had been among six players tied for second place on four-under-par after day two of the $US7 million ($8.45m) event.
Several emails and tweets from television viewers resulted in European Tour chief referee John Paramor calling for video footage of Dyson tapping down what looked like a spike mark with his golf ball on the eighth green on Friday during his second round.
Dyson was lying close to the hole and, after marking his ball, he then used it to reach forward and tap down something directly on his putting line. Paramor said: "Simon Dyson has been disqualified from the BMW Masters ... under the rules of golf (6-6d). Simon was found to have breached rule 16-1a, which states that a player must not touch his line of putt.
When the footage was reviewed, Simon was seen to touch the line of his second putt after marking and lifting his ball on the green.
