McDowell insists his best is still to come

GRAEME McDOWELL believes his best is yet to come as he prepares to defend his US Open title in Washington next week, eager to prove he is no major flash in the pan.

The Portrush golfer added his name to the list of recent first-time major winners when he prevailed at Pebble Beach 12 months ago to become the first European since Tony Jacklin in 1970 to win the US Open. And he followed it up with a star turn at the Ryder Cup to cement his place in European Tour folklore.

McDowell, though, is convinced there are more heroics ahead with his Pebble Beach victory acting as a springboard to further success rather than representing the pinnacle of his achievements.
