Just when he might have thought it was all over Colin Montgomerie was reminded today that not every American golf fan has decided to leave him alone.

"Cheer up - you could have a real job," said a spectator as Montgomerie walked through to sign his fourth round card in the United States Open at Olympia Fields near Chicago.

Wisely the 39-year-old Scot, who had finished well down the field on six over par after a closing 72, did not respond.

And nor did he choose to speak to waiting reporters. "Nope - not today," was the message relayed by United States Golf Association officials.

Montgomerie is still waiting for his first major title and next month's Open will be his 49th attempt - 51st if you include the two Opens he tried to qualify for and failed.
