It took almost 45 minutes yesterday for them to turn on the humidifier and close the roof to continue the match between Novak Djokovic and Olivier Rochus. This long delay might have killed Rochus' chance of pulling off the upset of the day.
The match went on to five sets and it was almost 11pm before the match concluded. This is the longest match for them since Andy Murray's famous night-time match with Stanislas Warwinka in 2009.
This is also the first time the roof has been closed for a match without the rain.
