It is so easy to talk about the Roland Garros-Wimbledon double—that elusive cross-Channel double slam achievement, all the more remarkable for being both held within a month. The greatest players have won it, indeed only the very greatest—Laver, Borg, Nadal, Federer.
There is a comparable achievement, however, in the trans-Atlantic slam, the Wimbledon-US Open double, with two grand slam victories at London and New York within the space of two months. Perhaps there has always existed a disconnect between the two—that European/American, Old World/New World thing. It is no less mighty a feat, nonetheless.
Like the said French-Wimbledon double, only the very best, too, have won it—the fact that a few more have done so does not by any means diminish the difficulty of it. Only seven in the Open Era can be said to have won the Atlantic slam, that latter, swifter half of the true holy grail of the Calendar Grand Slam.
There is added interest, of course, because Novak Djokovic stands in 2011 to add his name to this illustrious company, as he stands on the brink—maybe his best chance ever—of claiming his first US Open title.
