You need to just realize that some holes, like #9 are just not a birdie hole, unless you hole something from the bunker or the rough. All the other holes have their birdie chances, you just need to be on. The guys that can shoot under 60, are not doing it every time. But they know, just like everyone should know, the best place to leave your approach shot. Aim for uphill putts and straight putts.
Holes 1-9
1. Left of pin, about a yard or two long
2. Short and a little left (but the valley will usually make it still a right to left breaker)
3) Short of pin
4) anywhere close to pin leaves easy putt
5) short left leaves fairly straight
6) short and short left leave uphill putts
7) get it tight, but pin high right leaves easiest putt for me
8) happy with par, short of pin leaves mostly uphill
9) will aim for bunker, not going for birdie
Little practice in planning your next shot goes a long way. Hope that helps on the front.
