"I had to hit off my knees on nine, then on 14 I had half of my leg was up the wall and the other half was inside it," Ko recalled of her adventures in the bunkers on the course.
"There were multiple times today when I was like 'man, I could do with being lefthanded for a few of these shots.' But the sand is pretty fluffy, and I think the ball settles down after it hits the bank or it rolls in.
"It's not easy but for both of those I said 'okay, don't make a fool of yourself. All of your core exercises are right for this moment, so keep your core tight, keep your legs tight, and just hit it – and at least don't faceplant'."
The shot at nine seemed to turn things around, as she went on to finish one-under for the round.
"It's great that I'm around to play in the weekend. I've been trying to think these last few weeks 'what's meant to be will be', but at the same time it's like, man, if what's meant to be is for me to miss the cut, that would be disappointing," Ko said.
"I don't think you can take yourself out of it, especially around a golf course like this. If you're confident with the putter and hitting it pretty solid, I think you have a good chance. Minjee [Lee] showed [at the Evian Championship] you could be a few shots back and be able to be the one lifting the trophy.
"There's still so much golf, so you can't count yourself out. I'm just going to stay to my same strategies, be in a few less bunkers – none would be fantastic."
