Masters 2014: Darren Clarke says Augusta getting tougher

Darren Clarke says he believes the Augusta course is getting tougher after posting a closing 76 to end the Masters on nine over par.

"I played quite nicely but you are always on a knife edge here - I had hoped for better but it's getting tougher and tougher here," said the 2011 Open champion.

Clarke's card was marred by two double bogeys and three bogeys on Sunday, but he also recorded three birdies in his final 18 holes.
