Unless you've been living under a rock, you know tennis has been dominated by three men for the better part of the past decade, Federer, Nadal and Djokovic, who hold a combined 34 Slams and counting and an incredible amoung of weeks at #1 (basically ever since Federer became #1 after AO 2004).
Up until this Friday, the only men to beat all three of them in Grand Slam events was Tsonga, but with his win over Federer Murray has joined him
Active players only one win away from doing this include:
Del Potro - needs a win over Djokovic
Berdych - needs a win over Nadal
Soderling - needs a win over Djokovic
Might want to add Hewitt to that list mate. He actually has destroyed Nadal twice in a slam and gave a severe beatdown to Nole at the US Open in 2006 that arguably taught the Serb everything he knew about the game and created the monster we are seeing today. Just needs that elusive win over Rogi, but unlike the rest of the players on your list, he has time on his side...
