Another Sunday, another championship for men's tennis star Novak Djokovic. This time, it's in the Italian Open, 6-4, 6-4, over Rafael Nadal. With the victory, Djokovic's winning streak is up to 37 matches in 2011, 39 counting two Davis Cup matches at the end of 2010. Djokovic's website has a match-by-match log, which is available here. John McEnroe holds the modern (if not all-time) record with 42 straight match wins to open a season (1984).
