i was actually wondering earlier this week about gravity and the putting green. i play alot of very hilly courses.
i heard a commentator saying to never ground your club behind ball then you are never considered to have addressed it. something he learned from nicklaus.
the commentators seems to love delaet yesterday. the guy has crazy fast tempo i think. seemed to be much longer than anyone else. made it in 2 (the fringe) from 635 yards. not bad
