I watched a bunch of interviews with Lee Trevino a while ago. Regarding one of the majors when he beat Jack down the stretch (I don't remember which) he talked about his low ball flight and that on this particular tournament and final day(s) the greens were very receptive and could hold his low ball. He said that he knew then that he had a really good chance to beat Jack and he succceeded.

So Lee couldn't hit the ball high anytime the situation called for it. At least not with the same degree of precision as he had when he hit it low.
