Roger Federer is already through to the semifinals by winning his first two matches without dropping a set and today will face Juan Martin del Potro. David Ferrer faces Janko Tipsarevich in the other round-robin match.
If Federer wins a set off of del Potro he will be at the top of his group and thus play Murray in the semis while Djokovic will play either Del Potro or Ferrer (whichever wins by losing the fewest number of sets or games).
So, the most likely semifinal match-ups are Djokovic vs Ferrer and Murray vs Federer with a Djokovic-Murray final match for the title of player of the year on the line.
