Have you ever lost a match 6-0 6-0? Well, Maria Sharapova lost a pro match by that score to Lindsay Davenport a couple years ago. Have you ever lost a match in which you had match points? Roger Federer did during an epic match against Rafael Nadal. Ever totally whiffed on an overhead or hit a serve off the top of the frame over the far baseline? If you watch enough pro matches you may have witnessed these surprising
moments and a few others. But how is it possible for an elite, professional athlete, one of the very best, if not the best in the world, to miss such a big chance, e.g. match point, or blow such an easy shot, e.g. a sitter overhead. Actually, it's not that surprising if you really think about it. Tennis is a game of precise timing and critical moments which can vanish with a slight loss of attention or when a player is just having a bad day... don't we all from time to time?
