The 36-year-old American brothers, who are guaranteed to finish the year as the number one ranked doubles' team, now head to the World Tour Finals in London on November 9 looking for a 10th tournament victory of the season.
Both teams forced a break in the opening set before it went to a tie-break, which the Californians won 7/5.
However the newly formed team of Matkowski and Melzer broke Bob Bryan's serve in the final game of the second frame to snatch the set and force a match tie-break up to ten points.
