Re: There is no finish line...
Yet to come my personal favorite would be the as-yet-unacheived "career double slam." It means, 2 or more at every slam. would that be crazy or what? One more Rolland Garros and he's done. (Laver did it but only half of those were in Open era, and back then the slams were not played on as many different surfaces.) OK I did not say it would be easy!
