Bradley Dredge, a winner already this summer on the Challenge Tour, carded a best-of-the-day 67 to take the lead at halfway in the BTC Slovenian Open in Bled.
It gave the 26 year old Welshman a 36-hole total of 135, 11 under par, and a one-shot lead over Ireland's David Higgins.
Dredge, who won the Is Molas Challenge in Sardinia last month, carded one eagle and seven birdies in his 67, a figure matched by Stuart McGregor with an eagle and six birdies, which enabled the Scot to climb into joint third place on nine-under-par 137.
He shares third spot with overnight leader Dominique Nouailhac of France, who carded a 70, and Thomas Norret of Denmark with 68.
Higgins went one better than Dredge and McGregor. He carded two eagles and five birdies in his second successive 68 to be in the running for the title for the third successive tournament.
The cut came at two-under-par 144 and 50 players will contest the final two rounds over the weekend.
