Berdych held his service twice but couldn’t stop Federer from winning at 6-4, 6-2. In the second, however, it was Federer, who ruled with a 4-0 lead. At 4-4 in the first set, Federer broke Berdych and served out for the first set. Once Federer got into his rhythm, there was no stopping him. However, Berdych’s own awful poor service allowed the Swiss to nullify his disadvantage. But early on, it was Federer, who began surprisingly poorly as he double-faulted twice and dropped his serve.

And when the Swiss came on to serve he dictated terms to Berdych, whose first-serve performance was a woeful 44%. Federer’s returns of the second service were stinging and irretrievable. Berdych realized how costly it was to miss the first service because Federer played his second service with an unexpected ferocity.
