US PGA 2013: Graeme McDowell seeks third-round boost at Oak Hill

Northern Ireland's Graeme McDowell believes he needs to shoot a 65 or 66 on Saturday to get into real contention at the US PGA Championship.

McDowell carded a 69 on Friday to lie on one under par after two rounds at Oak Hill.

That put him eight shots behind leader Jason Dufner, and the Portrush player admitted he would need more joy on the greens to get into the mix for Sunday's final round.
