Oh so very close..... I almost aced a par 7 hole

. Let me tell you the story. Lined up on the par 4 10th hole at a course here. Noticed that the course was almost empty so I decided to pull out my driver and hammered my tee shot. I watched that ball fly 200 or so yards then curved and started coming back along the par 3 11th

. Went to look for the ball and it was 6 feet from the hole. I about laughed my butt off after I saw that. Good thing there wasn't anybody on that green. Any tip on how to cure my "boomerang" slice?
