Tiger Woods completed one of the most incredible comebacks in sporting history when he won his first major in 11 years but whilst everyone was celebrating it wasn't a happy day for betting firm William Hill.
Ever since Tiger Woods came back to golf the question was whether or not he had it in him to win one of golf's majors again.
At the end of last year the 43 year old won the Tour Championships to suggest that he was getting closer, especially after a second place at the USPGA Championships and a sixth place at the Open in 2018.
On Sunday he finally realised the dream of adding to his major wins by winning the Masters by one stroke and collecting his fifth green jacket at the Augusta National.
It was an extremely popular win around the world but there was one place that probably wasn't enjoying it, not that anyone will shed any tears, the offices at William Hill.
In America one punter placed an $85,000 bet on Woods winning the Masters, two days before it teed off, and won $1.2 million from the 14/1 odds.
Nick Bogdanovich, William Hill US director of trading said in a statement, "It's great to see Tiger back. It's a painful day for William Hill - our biggest golf loss ever - but a great day for golf."

When the back nine started the punter was probably sweating a little bit with Woods two shots behind Francesco Molinari and the Italian not looking in any danger of slipping up.
Molinari was on course for his second major in a year but Amen Corner had other ideas and he double bogeyed the 12th after going into the water.
By the time the pair got to the 15th there was a five way tie for the lead but Molinari again went into the water, picked up a double bogey and his chances were gone.

Woods continued his pursuit but his two shot lead was proved to be tighter than anyone thought. Brooks Koepka had a birdie chance at 18 but missed and when Woods bogeyed the last it showed how close we were to a play off.
Fortunately the American saw it out and won his 15th major, 11 years after his 14th, and his fifth win at the Masters.
Can he make it to 18 and go level with Jack Nicklaus? Don't bet against it, I know one American who won't.
