D.Van Roost V.S S.Williams
The ball lands right on the mid-court, and bounces up nicely for Serena to give it a good smack. She uninvitedly does so, and whacks the ball so hard you would have thought she'd be better off playing on the ATP tour. But her attempted winner clips the net cord, and sails high up over the air, and over your head and the baseline, landing on the audiences' stand. You can't believe your luck and it took a while to realize that you have won the Australian Open, you go on to win all 3 other grand slams and becomes the first woman to go unbeaten in one tour year, winning 15 titles on the way.
