already gave u an example. simple example that the article is a total lie: Federer has never won simultaneously on clay grass and hard. still that point is as a record in the article, there are so many others like it. the only time fed ever won clay was on 2009 when he lost the US open. so it was not simultaneous! this article is a fan puffery. not that much of wiki is not.. idiotic waste of time!108.78.177.132
