Fisher shot 10 birdies and an eagle on his way to a 12-under-par first-round finish the etch his name into the history books.
The Englishman, born in Chingford, London, became the first man to ever fire under 60 at a European tournament.
There have been 10 sub-60 rounds recorded on the PGA with Jim Furyk recording both a 58 and 59.
Brandt Snedeker was the last player to shoot a 59 at the Wyndham Championship last month until the world No 287 dug it out of the bag this afternoon.
Fisher is delighted to have joined an exclusive list of stars to have achieved such an incredible score.
“It feels great,” Fisher said.
“I started off the round great with three straight birdies and then kept it going. I saw that you guys were out here and it was in the back of my mind all day.
“I’m just pleased that I two-putted there from 40 feet on the last.
“It was a great day, my caddie was great, it was very different to a couple of years ago on this green fighting to keep my card.
“I had that in the back of my mind, thinking ‘do you know what? Things could be worse’.
“After saving par on the 16th I said to my caddie “We’ve got a couple of holes just to enjoy it’.”
“It was fun, I tried to enjoy it and thankfully I got over the line.”
Golf stars from around the world have since taken to Twitter to hail Fisher for his efforts.
And European Ryder Cup skipper Thomas Bjorn led the praise.
“A special moment for such a special guy,” he wrote. “Couldn’t be prouder of you @olifisher1.”
