Fox says it was one of the best rounds he's ever played.
"Probably the best round I've played in a tournament," Fox said. "I would not have thought 64 was out there at the start of the day. It looked like there's a few good scores from the guys.
"I think the only saving grace with this wind direction is you either play a hole straight down or straight into. There's not too many cross breezes. I made a couple of eagles obviously, which was nice. I hit a lot of shots inside sort of 15‑foot and made a couple of those, which is not really what you expect to do today.
"I kind of never really felt like I was under any pressure out there, which in conditions like this, that's always nice. Looks like it's going to be a couple short but I'm certainly not complaining."
