He's been hitting it really well, but haven't been able to get much out of the round. Made the third birdie of the day at 18 now, but with two bogeys only one under par for the day.
One under par after three rounds will most likely not be enough. If he's going to have any chance at winning, he will need a great round tomorrow, 65 or less. Today's round could've been 65 or better, but just didn't get the putts he needed.
