Oliver Fisher has carded the first round of 59 in European Tour history on day two of the Portugal Masters in Vilamoura.
The Englishman made 10 birdies and an eagle in his bogey-free 12-under-par effort to at last break the barrier, with 19 players having previously recorded official rounds of 60.
There have been 10 sub-60 rounds recorded on the PGA Tour - with Jim Furyk registering both a 58 and a 59 - the most recent of which came from Brandt Snedeker at the Wyndham Championship last month.
Fisher started with three birdies and then eagled the par-five fifth before adding further gains on the sixth and eighth to turn in 28.
He birdied the 10th and 11th and when he got on the green at the par-five 12th in two and made a third birdie in a row, he was 10 under for the day.
The 30-year-old got up and down from the side of the driveable par-four 15th for another birdie but needed to hole a 20-footer to save par at the par-three next after leaving his tee shot a long way from the hole.
He got on the par-five 17th in two and another birdie meant a routine par up the last sealed his place in the history books.
Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
