Harrington 'felt flat' on Oklahoma greens

Padraig Harrington arrived at Southern Hills hoping to add the US PGA Championship to the Open title he won at Carnoustie last month but a third round 72 left him 11 strokes behind leader Tiger Woods and his dream in tatters.

Harrington carded just one birdie as he dropped to four-over for the tournament, with his opening-round 69 now a distant memory.

'I played a bit better but a couple of things went wrong,' Harrington said.

'I don't know if I was flat going out or the poor start but I certainly felt flat and struggled on the greens.'

Harrington bogeyed the first, sixth and 10th and recorded the only birdie of his round at the par-five 13th.

'The pins were tougher today. Tee to green I was fine but I struggled with reading and pace,' he added.

'That's normally a sign of probably just being out of the tournament and I needed that bit of adrenaline to keep me going.'

Harrington admitted his hectic schedule since he won the Claret Jug has taken more of a toll on him than the 100-degree temperatures at Southern Hills this week.

'I don't have a problem with the heat, but I definitely needed a bit more in the tank after all that's gone on since Carnoustie,' he added. 'A bit of adrenaline was missing.'
