How many Grand Slams will Djokovic win in 2012? Djokovic is currently the hottest player on hardcourts and will probably go down as one of the best hardcourt players in history but how would you rate his chances at RG and Wimbledon this year?
Zero. By definition, there is only 1 Grand Slam to be won during 2012, and Mr. Djokovic, (or anyone else) would be indeed fortunate to accomplish it.
"A Grand Slam is the winning all four majors within a calendar year - and only that."
Thus, having to say Calendar Year Grand Slam or CYGS, is unnecessary.
Career Grand Slam became a fashionable term after the long drought in Grand Slam wins.
If the question is how many majors will he win this year, it's always difficult to predict prior to the season. I think 1 or 2, with RG and Wimbledon being the most difficult. Nadal or Federer have the best chance to win 1 or more (and they don't necessarily have to go through Djokovic to do it), Murray, Tsonga probably have the next best chance to win a major, but have to prove it first. Obviously, with a US Open under his belt, Juan Martin del Potro also has a chance if he is completely healthy. Ferrer's chances are slim, but if things fall right for him, it is possible.
