- Serena Williams's coach raised the prospect of the world number one skipping the remainder of the season on Tuesday as she struggles to come to terms with her failure to clinch a calendar Grand Slam. Patrick Mouratoglou told ESPN that Williams was intensely disappointed. "She was two matches away from something really big, so it was very painful," said Mouratoglou. "Any loss is very painful for her, but this one even more than usual. So it just takes time to recover from it, and when the motivation comes back, which I don't doubt it will, then it will be time to start tournaments again."
