I am still hopeful for Fed, but he worked the hardest in the last round. He needs to start quick against Rafa IMO. Agut is new to these stages, but I have paid more attention to him since the Murray match last year. He might well be able to give Novak a tough workout. He seems to end up playing pretty long sets. A grinding awkward player who seems to stick around and on a good day can beat very good players.
