Farsoe — Bradley Dredge hit five birdies in the front nine and finished with a 5-under 66 Friday as he surged to a three-shot lead amid windy conditions at the Made In Denmark tournament.
The Welshman, runner-up in 2014, bogeyed the 13th before finishing the second round with a birdie and four pars.
That left Dredge at 13 under, three clear of Sweden's Joakim Lagergren, who shot a 70 as the wind picked up at Himmerland Golf and Spa Resort.
South Africa's Richard Sterne (67) and Ryder Cup hopeful Thomas Pieters (71) are tied for third at 9 under.
Tom Lewis, who along with Lagergren and Pieters equaled the course record with a 62 in the first round, needed 10 more shots Friday to finish with a 72.
Shane Lowry, another potential Ryder wild card, improved on a first-round 75 by 10 shots. His round of 65 included seven birdies and one bogey. The Irishman is now 2 under.
Made in Denmark is the last tournament before Darren Clarke will make his three captain's picks for the European team.
Denmark's Soeren Kjeldsen eagled No. 6 and is among five players at 7 under.
