US Open 2015: Graeme McDowell on Chambers Bay's bunkers

Graeme McDowell says deep bunkers such as the one 90 yards short of the 18th green must be avoided at Chambers Bay, this week's spectacular US Open venue.

This week will be the first time a major is played at the course near Seattle, and views on the new venue appear mixed.

McDowell is aiming to repeat his 2010 US Open victory, when he triumphed at Pebble Beach.
