Six years after beating Tiger Woods head-to-head, England's Robert Rock achieved another personal milestone to claim the halfway lead in the Aberdeen Standard Investments Scottish Open.
Rock added a second round of 63 to his opening 64 at a defenceless Gullane for a halfway total of 13 under par and two-shot lead over compatriot Tyrrell Hatton and Sweden's Jens Dantorp, with Eddie Pepperell and 2015 champion Rickie Fowler another stroke back.
Lee Westwood was part of a four-strong group on nine under, with former Masters champion Trevor Immelman on eight under par alongside first-round leader Luke List.
Graeme McDowell was the sole member of the Irish contingent to prolong their interest heading into the weekend - as he shot a second round of 66 on Friday.
He now sits at five under par for the tournament - eight shots off the lead of Rock. However, Paul Dunne failed to make the cut by a stroke after he followed his opening 67 with a second round 70, leaving him on three under.
Darren Clarke and Padraig Harrington also failed to make the cut, after finishing the second day's play on level par and four over par respectively.
Meanwhile Rock, 41, has not dropped a shot over the first 36 holes for the first time in his career and is in pole position to secure one of the three qualifying places on offer for next week’s Open Championship, although he will be in Carnoustie anyway in his role as coach to a number of fellow players.
“I’ve started well in a few tournaments recently but it’s all about putting four rounds together and that’s the challenge,” said Rock, whose last European Tour title came in Abu Dhabi in 2012, where he played the final round alongside Woods and outscored the world number one by two, with Rory McIlroy finishing runner-up and Woods in a tie for third.
“Getting into the Open is everything, but you have to focus on this event first and play the course here before that. I hate missing the Open. I’ll be there whatever happens as a coach but it’s hard going just as a coach and not playing.”
Hatton won the Dunhill Links in 2016 and 2017 and revealed another victory here would be a welcome boost for his mother Karen, who lives near Inverness and is recovering at home after undergoing surgery to remove a tumour in her lung.
“It was lucky they caught it early,” Hatton said. “She will be watching on TV and I’ll try my best to be up there come Sunday.”
Despite adding a bogey-free 64 to his opening 65, Hatton was far from satisfied with his ball-striking, adding: “On some shots I literally didn’t even hit grooves. I was so far out of the toe I’m surprised it went forward to be honest.
“Me and the driving range aren’t friends so I’ll stay away from that, have the afternoon off and hopefully wake up with a good swing tomorrow.”
Pepperell finished fourth when the Scottish Open was last staged at Gullane in 2015 and needs another top-10 this week to have the chance of securing a second Open appearance.
“The two similarities between 2015 and now is that I haven’t played a practise round and stayed in Edinburgh both times,” Pepperell said.
“That seems to be the secret for me, just go out and have nice meals in Edinburgh and drink a bit of wine and come up here and play for four hours.
“I’m actually going to be commentating for BBC Five Live for a couple of days if I don’t play. Obviously I’d rather be playing but we’ll just wait and see.”
Scotland's Connor Syme set a new course record of 62 early in the day which was broken shortly before 8pm by Japan's Hideto Tanihara, who recorded an eagle and seven birdies in his first 15 holes to threaten the first 59 in European Tour history before eventually signing for a 61.
In contrast, five-time major winner Phil Mickelson missed the cut after finishing one under par, admitting: "I have some work to do on my game, I didn't play great. Now I'll have a couple of extra days to go over to Carnoustie and try to get it done."
