Karlsson leaps ahead as Westwood finally finds form
Karlsson, winner of the title in 1997 after a play-off, took full advantage of the morning session before rain and thunderstorms disrupted the afternoon play, to leap ahead of overnight leader Raphael Jacquelin of France.
The Swede hit two eagles and also chipped in on the seventh for one of his five birdies as he prepares to defend his European Masters title in Switzerland next week.
