And an intriguing line up in the semi finals. Federer in his 43rd Slam semi final against Chung who played incredibly against Djokovic, and Cilic who has looked very strong against Edmund who must be pinching himself. You would suspect a Federer Cilic final but both Chung and Edmund will be feeling confident after their last performances.
For the women Kerber has looked the class act but both Halep and Wozniacki have improved through the tournament. The questions remain about their ability to shut out the nerves but both have the game to win. Mertens seems nerveless up to now but to beat Wozniacki and one of Kerber - Halep would be astounding.
That both Nadal and Djokovic have injuries again will beworrying for promoters of upcoming tournaments. Given that, I suspect, neither would have played Davis Cup,they would gave a little recovery time planned anyway but were Federer to do as he did last year and avoid the clay season, and with Murray unlikely to be fit for it, a loss of another of tgd 'Big Four' would surely have an impact.
