Ryan Fox was surprised on Friday to find himself leading the Irish Open after the opening round, despite his impressive form this season.
Fox had eight birdies, including seven in his last 11 holes, in a flawless 8-under 64 at Mount Juliet. He has a one-shot lead over Frederic Lacroix, Jorge Campillo, Fabrizio Zanotti and Marcel Schneider.
Fox, who lost a playoff for the 2018 Irish Open to Scotland's Russell Knox, won the Ras Al Khaimah Classic in February, finished runner-up in the Soudal Open and Dutch Open and was third in the BMW International on Monday.
"I'm more surprised, to be honest, than anything else," the 56th-ranked Fox said. "I've been fighting it on the range the last couple of days and a 64 certainly didn't look likely early in the round.
"I made a couple of birdies but I was scrapping away and hit a great wedge on my eighth hole (the 17th) and made a few putts as well. So just one of those days that shows how important patience is in a round of golf."
