Ross Fisher's 61 was in a whole different world to what happened to Jamie Elson and Hennie Otto at the Irish Open - they both had a 12 on one hole.
Elson's came on the 211-yard sixth, where he put four balls in the ditch short of the green, while at the long seventh South African Otto blasted four shots wildly right and was forced to dip back into his bag each time.
They finished with rounds of 84 and 83 respectively, Elson signing off with a triple bogey seven just to make matters worse.
It was a bad day too for former US Open champion Michael Campbell, who is now going to fly back to his Sydney home for more treatment to the shoulder trouble that has contributed to a shocking slump.
The New Zealander's 77 means he has made only one halfway cut in 20 events since last October - and that after missing 14 in a row not long before.
Australian's Brett Rumford and Richard Green are well-placed at the halfway mark, tied for third just five shots off the pace.
England's Ross Fisher recorded the lowest round of his European Tour career to take a three shot lead after the second round of the 3 Irish Open at the Killarney Golf and Fishing Club.
Fisher, who began the day two under par, made ten birdies and avoided dropping a shot to surge clear of the chasing pack on 12 under par and eclipse the 63 he shot en route to winning The European Open in 2008.
Italy's Francesco Molinari, who carded a five under 66, was Fisher’s nearest challenger on nine under par.
Fisher appeared on course for The European Tour's first 59, having birdied ten of the opening 14 holes, including three to eight and 11 to 14.
However, he could only par the last four to go round in a still outstanding ten under par 61.
Fisher, who won the Volvo World Match Play in Spain last November, said: "It's pretty flawless golf to be fair.
"I got off to a steady start, a couple pars on the first two, and then the putter caught fire really. I had a nice little run.
"It was obviously a shame that it came to an end on nine, but I just kept on hitting good shots and got on to a little patch on the back, as well. I had a chance on 15 from eight feet; unfortunately I pulled it."
"All I wanted to do was give myself chances coming in the last four holes, and I gave myself four good looks at birdie. Unfortunately I didn't make them so I have to be satisfied with 61."
Nine players were tied for third, two shots back from Molinari, including Ireland’s Padraig Harrington and Northern Irish pair Rory McIlroy and Michael Hoey.
