Fed has not lost a set so far. I don't think he will do so in the final as well. However, I must admit that
I am not so confident about my number of sets prediction, although I am very confident about the final result.
Sure, Cilic played lights out in USO'14. But, I don't think it is a repeatable experiment.
Unlike some other folks, I don't think Fed was physically tired during that USO match. But, I do think
Fed was mentally tired; however, that was not the primary cause of his loss. I think he would have lost
that day as it was an extraordinary performance by Cilic (kind of reminded me of Rosol taking out Rafa at
Wimbledon with booming serve and lights out game).
I voted for Fed in three. But, even if Cilic wins a set or two, I do believe the choker in him will
make an appearance soon.
I think the only way Cilic can win this match is in straight sets with a repeat of lights out performance.
If it is anything other than lights out tennis, Fed will find a way to win and/or Cilic will find a way to
choke (see W'16).
