Because the Murray-Nalbandian match was going on and on, and they were going to run out of light. It happens from time to time on the showcourts, especially at Wimbledon, where they start play so late in the day and don't have lights.
Because court no. 2 is the 'graveyard' of champions
A man may fight for many things. His country, his friends, his principles, the glistening ear on the cheek of a golden child. But personally, I'd mud-wrestle my own mother for a ton of cash, an amusing clock and a sack of French porn.
Don't get me wrong as a Scot I'm very happy for Andy doing so well. But I think it's stupid that wimbledon think it's a good decision to have the world number 300 against someone who i don't think is in the top 20 on centre court. That game went on until quite late so the Serena match was moved.
Murray - Nalbandian wasn't a Centre Court standard match but what you have to realise is that Murray has been receiving huge media coverage here in the papers, radio & tv. The general public who have no real interest in tennis have been paying him a lot of attention so he was always going to be on CC due to the level of UK interest. This match was always going to get more tv viewers than the Craybas - Williams match which should have replaced the men's doubles on Court One which was the 4th match on that court and started pretty early.
