Irishmen Graeme McDowell and Rory McIlroy are both still in contention for the US Open, with the pair at two over and one over respectively.
Although they are still well behind leader Ricky Barnes, the pair understand that the thin nature of the margins involved and the severity of the weather conditions means anything can happen.
McDowell is frustrated with his failure to capitalise on some chances but reckons he is one quality round away from being right in the mix.
"It leaves me nine shots back but I still feel like I am in this tournament. You just have to be very patient out there," he said.
"I watched a bit of the coverage yesterday and saw guys making birdies all over the place and when you are watching it you feel you can just go out and do that too but as soon as you start missing fairways or hitting it the wrong side of the hole then you are struggling.
"It's tough, it's a US Open and par is supposed to be a great score. You have to try and keep remembering that."
"I am in there for the final two rounds, whenever they may be, and I have a chance to do something here - I am going to need a good one, a 66 or 67 in one of the remaining rounds but I'm playing well enough to do that."
McIlroy gave an insight into how the constant rain interruptions have affected him, and the generally gruelling nature of things.
"The conditions do throw you a bit off your rhythm. I know everyone says you just take it one hole at a time but you don't know how many holes you're going to get in," said the Belfast man.
"I've played six holes today and I might only play six holes. I didn't play any on Thursday and I played 30 yesterday. I went to bed at 11pm and got five hours sleep before coming to the course. It's a gruelling test in so many respects.
"It's a US Open course and its tough and when you miss a green it's difficult to get up-and-down. The difference of two or three shots in a round is nothing really. It's a couple of putts here and there and a missed fairway, that's all," he said.
