Tiger Woods is widely regarded as the greatest golfer of all time for so many different reasons.
Woods dominated the sport more than any other player in history, and some of his achievements will probably never happen again.
No golfer has ever won all four majors in a calendar year, but Woods once held them all at the same time.
He won the US Open, Open Championship, and PGA Championship in 2000, and The Masters in 2001 to complete the famous Tiger Slam.
Woods was seemingly unstoppable at the peak of his powers, but one unlikely player almost stopped the historic achievement from happening.

Bob May almost beat Tiger Woods at the 2000 PGA Championship
Woods had already won six tournaments in 2000, including the US Open and The Open, before the PGA Championship at Valhalla.
He was the leading contender heading into the week, and when he took the lead after 36 holes, many assumed he would cruise to victory.
However, Woods’ final round 67 was not enough to win the trophy as Bob May shot a 66 to force a playoff.
May never won a single PGA Tour event in his career, so it was an almighty surprise that he was able to outperform the world number one on Sunday.
Unfortunately, May (E) could not complete the miracle in the three-hole playoff as he finished one stroke behind Woods (-1).
At least he will always be remembered for giving Woods the biggest scare on the way to the Tiger Slam.
What Tiger Woods and Bob May said after the 2000 PGA Championship
Woods implicitly complimented May by saying that he was pleased to beat “the best players in the world” at the PGA Championship.
“Anytime you get to play against the best, and be able to come out on top against the best, it’s always going to be more satisfying,” he explained, via the PGA Championship website.
“The last two years, the PGA Championship has drawn the best field, and I’ve been very fortunate to be able to win. But to be able to tee it up and go toe-to-toe against the best players in the world, that’s what you dream about.”
Meanwhile, May was thrilled to have “proved to people” that he could compete with Woods and the other top-class players, despite not winning.
“I wanted to concentrate real hard out there today and, you know, prove to people I can play out here,” May said in his press conference.
“It’s not a question anymore. I went out and played a good solid round of golf, and was just one shot too short.”
