Luss, Scotland -- Darren Clarke increased his tournament lead to three strokes Friday, halfway through the European Tour's Barclays Scottish Open.
Despite heavy rain conditions throughout the round, Clarke shot a 4-under-par 67 Friday and is at 10-under 132 after 36 holes.
He is three strokes ahead of Edoardo Molinari, who had a 69 in his second round. Bradley Dredge and Peter Hedblom, who also each shot 69 Friday, are tied for third at 6-under. Francesco Molinari, also with a second-round 69, is in fifth at 5-under.
Clarke, whose first-round lead was one stroke, had five birdies and one bogey Friday. He played the back nine first and three-putted from 20 feet on No. 11 for his only bogey of the first two days.
