Djoker and Berdych have a history of playing tight matches. Matter of fact, in their last four meetings together, no one has managed any straight set wins. All the wins have been three setters. Since both are in solid form, I expect the same for this match. Even though Djoker may pull this one out, Berdych wont go out without a fight.
I believe the Over 21 games is an easy winner today.
