Bryans edge Pospisil-Sock for Miami title

   Bob Bryan and Mike Bryan are developing a nice rivalry with Vasek Pospisil and Jack Sock.
   The top-seeded Bryans edged second-seeded Pospisil and Sock 6-3, 1-6 [10-8] on Saturday to win their fourth Miami Open title.
   The 36-year-old Bryans evened their record against Pospisil and Sock at 2-2, including a loss two weeks ago in the Indian Wells quarterfinals. The teams met for the first time in last year's Wimbledon final, won by Pospisil and Sock 7-5 in the fifth set in their initial tournament together.
   The Bryans, former Stanford All-Americans, have won 33 Masters 1000 crowns and 105 titles as a team.
   All of the Miami doubles finalists except Pospisil live in Florida, which has no state income tax. Pospisil, a 24-year-old Canadian, lives in the Bahamas.
   The Bryans grew up in Camarillo in the Los Angeles area, and the 22-year-old Sock is from Lincoln, Neb.
