Doug, hope he does have a better putting round. I've read the stories about the short game and clearly he kicked away a couple of strokes with the miss on the short putt and a bad bunker shot. Else he made the short chances for Birdie and I think made the putts that I would call realistic.
My opinion looking at the round he didn't give himself good chances to reduce his score on the other holes. I think it had as much to do with his approaches as his putting. Just as an example here are some distances that he 2 putted from, 48FT,41FT,24FT,26FT,25FT,19FT,18FT to be realistic I don't care who you are your not going to make many of them.
Par 5's remain the key they are Tigers strength and he need to get back to playing the 5 pars under par as opposed to even or over par.
