Everything in the round started well and then arrived at the 6th. Straight down wind the 202 yard par 3 at Sprowston Manor. Selected a 4 hybrid to play a slight fade and connected purely. As the ball landed on the green i originally thought it had gone to far.... but my playing partner said it went in which i didnt believe and didnt really celebrate but as I got closer he started to record on his phone. As we approached the hole there it sat in the bottom of the cup. And it was a slam dunk and damaged the ball on the ferrel on the bottom of the flashback. This is when we celebrated. This day I went on to record a record round of 75 which was +4 over par. I retired the ball due to the damage and have it in a glass unit at home to remember the hole in one.
