Serena Williams is through to the last four of the US Open, but if she has to dig any deeper she might find herself halfway to Australia. For the third successive match she needed to recover from a set down, this time against the sorcery of the event's most unlikely quarter finalist, Tsvetana Pironkova. The American proved to be Mother Superior, but could only admire the resourcesfulness of unranked Pironkova, playing her first tournament in more than three years. 'It just showed me how tough mums are, if you can birth a baby you can do anything,' said Williams. The Bulgarian was spent towards the end, and will now travel back to Bulgaria to see her two year-old son.
