It was reported that Djokovic was the first to win 5 Masters 1000 events in one calendar year. A great achievement. But lets not forget that Rod Laver was first to do this in 1970 at the age of 32. The Championship series was the direct fore-runner of the Master 1000 series. In fact to underscore their equivalency, the first 2 years of the Masters 1000 series (1990-1992) - it was known as the 'ATP Championship Series Single Week' In 1970 Laver didn't do that well in the Slams but in the Championship level events he was head and shoulders above the rest winning: Johannesburg Los Angeles London Philadelphia Sydney (this tournament had a deeper field than the Australian Open that year and best of 5 set matches) http://en.wikipedia.org/wiki/Grand_Prix_Tennis_Championship_Series_1970-1989 So, no Djokovic wasn't the first to do five. I do think that when comparisons between players are done quoting their Masters 1000's wins the Championship series numbers should be included - otherwise what do you do about players whose careers overlapped both eg Beckers? It is clearly inaccurate to list only the 5 Masters 1000's he won when he won another 8 Championship series - 13 seems about right I feel. I should also add that Connors won 5 as well in 1976.
