US Open: Graeme McDowell looks to improve position at Pinehurst

Graeme McDowell admits he needs a "big weekend" after a disappointing second-round 74 at the US Open.

It put the 2010 champion from Northern Ireland on two over par for the tournament led by Germany's Martin Kaymer on 10 under.

McDowell felt Kaymer was in control of the tournament saying: "No-one else is going to get to 10 under, that's a fact."
