Graeme McDowell boosted by US Open challenge

Graeme McDowell says his belief in his ability to win another major has been renewed after tying for second place at the US Open at the Olympic Club in San Francisco.

The 2010 US Open champion was left to rue a slow start to his round and "too many missed fairways".

McDowell compared playing a major championship to "a rollercoaster ride" and said he was "very proud" of his efforts, taking a "huge amount of positives" from the week.
