Firstly, here’s my scorecard for the semi-finals:

Serena Williams defeats Agnieszka Radwanska in straight sets   (Correct)

Angelique Kerber defeats Johanna Konta in three sets   (Correct winner but in straight sets)

Novak Djokovic defeats Roger Federer in four sets   (Correct)

Andy Murray defeats Milos Raonic in four sets   (Correct winner but in five sets)

And the final predictions:
Williams defeats Kerber in straight sets

Djokovic defeats Murray in four sets

If both predictions come true, there will be ties for some historical landmarks.  More on those later – if they come true, that is.
