Joel,
Check out the other Baltusrol thread, where I posted an aerial of the course. You can see that #7 has maybe 20 yards between the back of the center fairway bunker and the green, although in that pic, 10 of those yards are rough. Don't know if that rough is mowed to fairway height for the PGA.
#7 is in the upper right of the 'bottom bulge' of holes.
