US Open celebrations catch up with McDowell

US Open champion Graeme McDowell admitted a Pebble Beach hangover contributed to him not putting in a better display at St Andrews.

The Northern Irishman fell back to three under at the finish having reached five under through 10 holes of his final round.

After his major breakthrough win last month, where he became the first European to claim the title since Tony Jacklin in 1970, McDowell confessed he partied hard.

The 30-year-old accepted he came into this week not at his peak but, having come so close to making a challenge, he left slightly disappointed.

‘I'm not quite myself at the minute in terms of getting my head screwed back on but after these last two weeks it could have been a lot worse,’ he said.

‘I played beautifully today, the best I've played all week but I finished like an absolute amateur - three-putting 16 and four-putting 17.

‘I didn't quite get the job finished and it has been a frustrating week.

‘Tee to green I controlled my ball pretty but I putted diabolically, which is unlike me on this type of green.

‘I didn't clean up this week the way I cleaned up around Pebble Beach.

‘I gave myself plenty of chances to compete but from four to 10 feet I putted badly.

‘It would have been nice to have rescued a few shots. I could have gone really crazy but missed a ton of chances today - maybe I used up all my putts at Pebble.’
