Shane Lowry is just four shots off the pace after a second round of five-under 67 at the Alfred Dunhill Links Championship on Friday.
The Offaly native followed up four birdies and a bogey on the front nine with a bogey on the 10th hole, an eagle on the Par 5 12th, before another bogey on the 14th. He settled to birdie two of his final four holes.
Also on six under is John Murphy, the 22 year-old Kinsale golfer was three under for his second round. Northern Ireland’s Michael Hoey was just one stroke off the first round leaders on Thursday but he carded a disappointing three over par 75 on the Old Course at St Andrews. That leaves him four under par overall. Paul Dunne also hit a disappointing 75, leaving him two under par.
Twice winner Tyrrell Hatton overcame three bogeys on a frustrating back nine to card a two-under 70 and take a one-shot lead into the weekend.
The Englishman started the day at eight-under and looked in control with two early birdies before tough windy conditions saw him bogey the 10th, 13th and 16th holes at Kingsbarns, ending the day on 10-under for the tournament.
Compatriot Daniel Gavins sank an eagle on the par-five 14th to move into second place with a four-under 68 at Carnoustie, while former Masters champion Danny Willett made the most of a lightning start - two birdies and an eagle in his first three holes - to stand two shots back following a round of 69.
The championship is being held across three courses in rotation over the opening three days - the Old Course at St Andrews, Carnoustie and Kingsbarns - with the final round to be played at St Andrews.
Tommy Fleetwood, who played alongside Hatton in Europe’s Ryder Cup defeat at Whistling Straits last week, carded a one-under 71 that tied him for fifth at seven-under.
