Bryan and Sock out to cap incredible six months

American duo Mike Bryan and Jack Sock have the chance to complete a memorable six months together when they play for the title at the ATP Finals on Sunday.

Bryan, who has spent a career accumulating doubles titles with twin brother Bob, teamed up with Sock after his sibling suffered a hip injury and the duo have thrived.

On Saturday the fifth seeds beat Jamie Murray and Bruno Soares 6-3 4-6 10-4 at the 02 Arena and will take on French pairing Pierre-Hugues Herbert and Nicolas Mahut in the final.

Bryan will be seeking a fifth title at the season-ender, but the first without Bob.

"It`s going to be a great day. I am going to be super excited and hopefully I can get to my fifth title here," he told reporters.

Bryan first paired with Sock at Queen`s Club this year and a few weeks later they won Wimbledon and followed that by taking the U.S. Open title together.

"We started off with a great moment in London, winning Wimbledon," said Bryan.

"If we could finish it off strong in London again, winning `the fifth slam` then that would be pretty special."

Herbert and Mahut, who will be in action for France in next week`s Davis Cup final, beat Juan Sebastian Cabal and Robert Farah 6-3 5-7 10-5 in the day`s second semi-final.
