I know the feeling. Been a long time since I’ve been in the 70’s.
Sitting at 69 on par 4 #17 tee. Hadn’t hit a poor drive on the day. Faded it into the fence line (right side). Ball was unplayable. I wound up with a 7.
#18 tee. Par 4. No worries at all. Slice OB right. Almost missed the ball as it went way off the toe. Finished with a double bogie #6.
13 strokes on final two holes (5 over). Bogie, bogie would have put me at 79.
I hadn’t had anything worse than a bogie on the day. I never felt any nerves at all and still lost my final two drives right. Finished with 82.
Still all good. My closest competitor finished w/85.
