Richie Ramsay shot a 4-under 66 to take a two-shot clubhouse lead in the second round of the European Masters.
The 2012 champion from Scotland had a 12-under total of 128 to sit two strokes clear of American Brooks Koepka, who shot a second straight 65 on the 6,848-yard (6,262-meter) Severiano Ballesteros course.
Another American, David Lipsky, had a 64 to sit a further shot back.
Ryder Cup rookie Victor Dubuisson of France carded a 67 to head a group of players on 8 under.
Edoardo Molinari of Italy, who shared the overnight lead with Ramsay, only managted a 70 to join Dubuisson.
The cut was projected at 1 under, leaving 2010 winner Miguel Angel Jimenez — one of Europe's five vice-captains for the Ryder Cup this month — in danger of missing out after a second straight 70.
