Actually, I was using another competitor's ball but due to scuff marks, i changed my ball a hole before this par 3. I went into my golf bag and pulled out a new sleeve of titleist Pro V1 on hole #12. I was saving these ball for my next tournament but decided to use a new ball. Happy that i did. On hole #13, a 165 yards to the hole. I pulled out my 160 yard club, which is my #5 hybrid and took a slow easy swing not wanting to dirty or scuff the ball and hit it straight to the green. It landed approximately 160 yrs and rolled straight to the pin and disappeared in the hole. I was hesitant not knowing for sure it went in, but my partner's yelled and cheered!!!. "You got hole in one".
