"I probably need to throw a couple of thanks out too. I struggled last week here with my back and I have my physio out here, and the Tour physio has helped me out over the weekend and I feel 100 per cent this week which was nice.
"Shaun Norris was nice enough to give me a putting tip on Tuesday when we played a practice round together and that seemed to work pretty well too, so big shout-out to those guys."
Known for his big hits off the tee, Fox also backed up his power with finesse on the greens.
"I hit it in the greenside trap a couple of times and got up and down. It is the kind of golf course where you feel like you've got a lot of opportunities and it was nice to take advantage of those today and then hole a couple of longer putts on some of the tougher holes to keep the round going.
"I worked hard today on just focusing on every shot, obviously my body felt a bit better today than last week, I felt like I could do what I wanted to do and I wasn't fighting it so hopefully I wake up tomorrow feeling good and I can keep doing what I'm doing."
Fox is searching for his first event win since 2019 and his second on the Tour.
