Novak Djokovic inflicted the first clay-court defeat on world numero uno Rafael Nadal in nearly two years and kept his own unbeaten start to 2011 as he won the Madrid Open final 7-5 6-4 at the Caja Magica. Djokovic extended his record in 2011 to 32 consecutive victories, the second best start to a season after John McEnroe’s 42 matches in 1984.
