Tom McKibbin headed for the clubhouse two shots off the lead after the weather-affected Alfred Dunhill Links Championship was suspended.
Home favourite Robert MacIntyre battled brutal conditions at Kingsbarns to grab a share of the clubhouse lead before the second round ws halted.
McKibbin still has one hole to play. He sits on 10-under, two behind MacIntyre early starter Richard Sterne who posted a bogey-free 67 on the Old Course at St Andrews to set the target at 12-under just as the weather worsened.
Sterne looked unlikely to be caught as strong winds and heavy rain battered all three host courses across the afternoon. But Ryder Cup star and local hero MacIntyre rose to the occasion, joining Sterne at the top by signing for a second straight 66 after making seven birdies and a solitary bogey in the worst of the weather.
Sterne's countryman Louis Oosthuizen was one shot behind the co-leaders after carding a 68 at Kingsbarns, one ahead of the large group containing Scotland's Scott Jamieson and McKibbin.
Conor Purcell got home in a one-over 73 to sit on six-under, two clear of Padraig Harrington who shot a second consecutive 70.
MacIntyre began his second round at the 10th tee at Kingsbarns on Friday and made a bright start, picking up birdies on the 11th, 12th and 14th before parring his way to the turn.
The world number nine picked up another shot at the first after sending his approach to five feet but bogeyed the short second.
He bounced back in style, though, firing birdies at the third and fifth - from around 20 feet - before tapping in for another from close range on the ninth to move alongside Sterne at the summit.
MacIntyre said: "It was almost a perfect round of golf, especially once the weather came in, just a lovely round.
"It's difficult when it gets this windy. It's hard to hit the ball good with the wind.
"So I was having to try and fight the wind on certain holes and wasn't comfortable. But I made some beautiful shots. Yeah, putted solidly in the wind."
England's Nathan Kimsey made nine successive birdies at the Old Course to write his name into the DP World Tour record books as only the third player to achieve the feat after Matt Wallace and James Nitties.
Ryder Cup star Matt Fitzpatrick and five-time major winner Brooks Koepka are among those in the grouping at eight-under par, with the latter still having three holes to complete of his second round at Kingsbarns.
Tommy Fleetwood is one struck further back in the group at seven-under, having concluded his second round.
Those with holes still to complete will return to the course at 8am on Saturday before the third round begins at 12.30pm with a shotgun start.
