London - Rain brought more misery at Wimbledon on Tuesday with Centre Court's 80 million ($125 million, 100 million euro) roof moving back and forth as often as the players.
The roof was closed on the All England Club's main arena in the run-up to the start of play, but then reopened just before Spanish seventh seed David Ferrer was due to begin his last 16 clash against Argentine ninth seed Juan Martin del Potro.
However, as heavy rain began to fall, the roof was shut once again, delaying the scheduled midday 13:00 (SA time) start.
On Court One, Andy Murray and Marin Cilic, who had started their last 16 tie on Monday, played just one full game before they were halted with the British fourth seed leading 7-5, 4-2.
France's Jo-Wilfried Tsonga won three games on the trot against Mardy Fish on Court Two to lead the second set 4-1 after the American had claimed the first set on Monday.
On Court Three, Germany's Florian Mayer had extended his lead over Richard Gasquet to 6-3, 6-1.
German 27th seed Philipp Kohlschreiber was 3-1 up in the first set against US qualifier Brian Baker on Court 12.
