Adam Scott has described himself as "disappointed" after slipping to seven-over-par after the first two rounds of the US Open.
The Masters champion recorded bogeys on four of the opening six holes at Merion on day two, and must wait to see if he makes the cut.
"I was a little disappointed with the way I played today," Sky Sports News quotes the Australian as saying.
"I just lost my rhythm early this morning when it was a bit cold and windy and just fought with it all day long and the putter kind of cooled off. So I would have liked to make some putts and then you're always happy.
"I still see those, you know, four or five-unders possible. It's difficult, but it's still possible with it soft. You just have to hit every shot perfect. And for one day, I mean, it is doable."
American golfers Billy Horschel and Phil Mickelson top the leaderboard at the end of day two.
