Berdych continued to roll with the momentum in the second set as well as he broke Federer in the first game and got another break in the seventh game. However, Federer broke back immediately in the next game and then held his service game to reduce the gap to 4-5 scoreline in the set.

In the fourth set, both players fought hard for their way and no breaks were exchanged until 5-3 scoreline where Berdych broke Federer and then served out for a place in the semis.
