Bob and Mike Bryan say they are developing a rivalry with the doubles team of Vasek Pospisil and Jack Sock, having played them in four big tournaments since the Canadian and American began playing together at Wimbledon last year.
The Bryans defeated the duo to win the Miami final, 6-3, 1-6, 1-0 (10-8), for their fourth career title in Key Biscayne.
The two teams have now split their four meetings, starting with Pospisil's and Sock's win over the Bryans at the Wimbledon final. The Bryans then won in Cincinnati before Pospisil and Sock took them down in Indian Wells, where they went on to win the title.
The 16-time Grand Slam champions have taken note of the rapid rise of the 24-year-old Pospisil and 22-year-old Sock, though both are still full-time singles players. Their climb up the rankings means the two teams could be meeting in big matches regularly.
"The rivalry is young," Bob Bryan said. "They're going to be seeded No. 2 now with those big results. When we meet, it will be in big matches, and that can only add to a nice rivalry."
Pospisil is No. 8 and Sock is No. 10 in the doubles rankings.
