Bethpage Black has only 7 holes where the fairway runs into the green. Since all of the par-5's have this feature, only 4 out of 11 par-4's have fairways running into the green, which seems incredibly low.
What courses have fewer, either on the par-4's or overall?
Pine Valley came to mind, but even it has 9 out of 18, if you count holes where the fairway stops 100 yards short of the green but re-starts at least 30 or 40 yards before the green itself.
