hole in one at glendale

First week back playing in league after a month,.. last to hit in my foresome, only one ball on the green about a mile from the hole,... Felt a right to left wind pin was back of green at 158yds, pulled my 7iron (AP2) hit a high slight draw which came back online right at the flag Then the ball dissappeared, my playing partners said it's in the hole, I thought it went pass the flag and rolled off the back of the green! When I got to the green didn't see an thing behind the hole,... so looked the the cup and there it was my first ever after 20 years of golf
