US Open: Clarke hopes sessions with Rotella can reignite form

Darren Clarke has turned to mind coach Dr Bob Rotella again as he aims to regain his form at this week's US Open at Pinehurst.

Clarke credited Rotella's help for turning around his game in 2011 when he won the Open Championship at Royal St George's.

The Northern Irishman has struggled for form since then but he insists that his scores have not been a true reflection of his game in recent months.
