Had some family around for pasta Sat evening so got my rounds in after they left. The champagne must of done something as I hit 8 under for round 3 and was 3 under for the first 7 holes in round 4 and 22 under for the tournament. Then hit a driver by mistake on hole 8 when I have hit a 3 wood on the 3 previous rounds. Tried a punch shot that went right into the water behind the green, a triple bogey and a bad temper which probably caused a double on 13. Managed a couple of birdies on 17 and 18 but the damage was done. Kicking myself because my course management had been very good and left myself ideal distances on many holes.
