US Open 2015: Shane Lowry maintains Chambers Bay challenge

Shane Lowry admits he is struggling to contain his excitement as he heads into the final round of the US Open only three shots off the pace.

Irishman Lowry, 28, again impressed on Saturday and was only two behind midway through Saturday's round before two late bogeys hindered his progress.

"You can't get ahead of yourself. A couple of times today, I did let myself think ahead to tomorrow and I gave myself a slap in the face fairly quickly," said the Offaly man, who is wearing black all this week as a mark of respect to the Irish students who died in a tragic incident in California on Tuesday.
