CBS offered a ground level shot (from behind) of DJ's second shot into #2 today (Sat). This is one of the highest elevations on the course. The view showed the "rough" at the bottom of the foreground... it looked at least three inches long! I don't think they didn't mow it due to rain. The ground would not be too wet to mow on top of that hill.
EDIT: I don't remember the "second cut" ever being more than 1/2 inch or so. Just enough to reduce the spin.
