I don't think there's a set time, it just seems to come out between 12 and 2pm the day before, but I'm 99.99% sure it will be:I think Djokovic wins regardless, he is the only one seems to be able to get into Nadal's head and make him play badly, look what he did to him in Australia. For Federer to beat them both at 38 years old would be one of his greatest achievements even for him, just cant see it happening.
@The Bridge Lad What time will they announce the order of play for tomorrow?
Djokovic vs RBA
Federer vs Nadal
Fedal were both on last yesterday, so rest wise it makes most sense, plus with that match likely to start around 4pm (assuming ND wins in 3 or 4), it will get the biggest ratings with people coming back from work to see the last couple of sets. I can't see any other scenario, and at least the first semi final won't last 6 and a half hours this year
