By Iain Rogers MADRID (Reuters) - Novak Djokovic was dumped out of the Madrid Open in the second round on Tuesday when he went over on his ankle and incurred the wrath of the locals on the way to a shock 7-6 6-7 6-3 reverse to Bulgarian Grigor Dimitrov. The world number one, who had a bye in the opening round, was already a break down to the unseeded 21-year-old in the second set when he twisted the same ankle he hurt playing for Serbia in the Davis Cup last month.

Rafael Nadal has repeated his criticism of the 25-second rule between points after being served with a warning for taking too long between points for the second day in a row. The world number five eased into the quarter-finals of the Madrid Masters with a 6-2, 6-3 win over Mikhail Youzhny on Thursday. However, Nadal was warned when facing break point on his serve early in the second set and he doesn't believe such a short period of time between points makes for a good spectacle.
