Scotland's Craig Lee took a one-stroke lead over American Peter Uihlein and Chile's Mark Tullo on Friday during the suspended second round of the Madeira Islands Open.
Lee shot a 4-under 68 to reach 9-under 135 at Santo da Serra Golf Club.
Uihlein, the former Oklahoma State star who won the 2010 U.S. Amateur, settled for a 64 after playing the first 12 holes in 10 under with an eagle and eight birdies. He bogeyed Nos. 15 and 16.
Tullo had a 69. France's Thomas Levet was fourth at 7 under after a 67.
Fog delayed play for 1½ hours and the round was suspended because of darkness.
