McDowell can win at Merion - Clarke

Darren Clarke believes Graeme McDowell has a great chance of adding to his 2010 US Open success when he plays at Merion, Pennsylvania next week.

Clarke, playing in the event after missing the Masters because of injury, said the shorter course would suit his fellow Northern Irishman.

"Merion gives him a fantastic chance of adding a second US Open to his CV," said Clarke.
