In July, the Bryans became the first team in tennis history to hold all four majors and the Olympic gold medal at the same time with a third Wimbledon title. They fell short of a calendar-year Grand Slam when they lost in the semifinals of the U.S. Open.
The twin brothers also won 11 titles in 2007 and 2010. They could win a career-high 12th title in a single season at the ATP World Tour Finals in London.
"We're not just looking ahead to 2014. We want to finish the season the way it started," Bob Bryan said. "We can see the finish line. It's only eight more days to the season. We've definitely put a lot of mileage on our bodies, but we can see it and we're going to try to race to the finish line."
The top-seeded Bryans avenged their loss to Peya and Soares in the final of the Valencia Open a week ago in Spain, breaking their opponents five times while dropping serve twice.
"I thought Mike, he returned fantastic," Bob Bryan said. "I don't feel like I returned my best match. I might go back to the practice court and hit a few more. But today was about Mike's return, I thought I did some good work at the net."
