The Grand Slam again!

Between Tiger Woods and Rafeal Nadal, who has the greater chance of completing the grand slam this season? I would go for Nadal. He has already won the Australian open. The French open, which is the next grand slam event, is his for sure. After all, he has won it the last four years and is unbeaten there. It is also played on clay court, where he is invicible! The next one, Wimbledon, he is again the defending champion. People might question his grass court expertise but he has reached the final the last three years and last season, won it. Finally, the US open. This is where he has so far not been able to achieve any result of any significant so far. For a player of his stature, it is surprising. Anyway, I will stick my neck out and say he will win the US open this year and with that, achieved the unthinkable of winning the Grand Slam.
As for Tiger Woods, let him win the Masters first before any talk of the Grand Slam can be entertained.
