Presnell, who earned the right to play the event via a dramatic Sectional Qualifying playoff, was learning the ropes as quickly as he could and was tapping into Ogilvy's knowlegde as an experiecned US Open campaigner and former winner.
"I had thought about not playing in Mexico last week but I have a job to do on the Nationwide Tour and unless something amazing happens this week it is not going to get me on the the PGA Tour so first things first.
"This is a dream to get into a major and for it to be the US open and to play on such an establishment as Olympic it is fantastic. It is a bit of an adjustment playing such a strong golf course as I don't play too many like this.
"Talking to Geoff on the way round it is clear you just have to bite your tongue and accept there are going to be some bad holes and hopefully a few good ones and just be happy with what the result is."
"I talked with my coach Darren Cole by phone last week and made a couple of adjustments and the ball is coming off the clubface pretty good, he added referring to the state of his game.
"This is a strong golf course in fantastic condition and it is exciting to be here."
Presnell plays at 9.16 in round one.
