SweetiePie, you may have seen my say this in a few other threads, but here goes again.
Before I start, by saying this, I'm not trying to say that "hey my game is better than yours" or anything of the sort. Hell, I barely have 200 Ranked Rounds Played, but I seem to have a grasp on Oakmont. I understand I'm not the best Oakmont[er] out there, and my scores will likely be topped soon.
Firstly, when I shot 57, I had 17 greens where I was putting. I had 17 because I holed out for Eagle on #2. Out of these 17 holes, I 1-putted 12 of them. Impossible greens? Very doubtful. I'm sure you're familiar with the ones that I, like you, struggled with.
#8 and #9 are the two I 2-putted on the front. On the back, I 2-putted #13, #16, and #18.
It's hard for me to give tips on how to control these putts. Everything I did that round was working. I couldn't miss. After three straight birdies on the back, I decided it was time to take it easy and try to save a good score and maybe shoot 60 if I'm lucky. I lipped a 40 footer on #18 for birdie, I made the putt of my lifetime and #15 from 25 feet away, and many other apocalyptic-esque hasppenings.
The weird thing is, the only advice I can try to offer you is don't try to make the long putts. I know this seems pretty hypocritical of me as I drained many long putts that round, but the weird thing is: I wasn't trying to. I told myself on some of these putts "Ok, I'm 40 feet away. I'm conscientiously aware that leaving myself a 5 footer coming back could result in bogey. We all know how hard it is to leave a putt short at Oakmont, so I decided to take A LOT off of that putt, enough so that I believed it would never get to the hole. I played a ton more break than I usually would and dinged it. What happened? It lipped the freakin' hole! Luckily it wasn't traveling too fast and I ended up with a 1 footer for the par.
The advice I want everyone to hear (whether brand new or a seasoned pro) is that you need to leave yourself with a simple putt coming back if you miss. Remember that pars don't lose a stroke, but bogeys take away that birdie.
Sorry if my egotistical rant is useless information, I'm just saying... that's what happened.
