Bryan brothers reach year-end final in style

The American twins will be going for their fourth title at the season-ender on Sunday against Brazil's Marcelo Melo and Croatia's Ivan Dodig, although they have not triumphed since 2009 when the event first switched to London.

Melo and Dodig beat Lukasz Kubot and Robert Lindstedt in a deciding set match tiebreak.

The Bryans dropped only seven points in a one-sided opening set, an unusual occurrence this week when the doubles matches have been fiercely contested, but they had to work a bit harder in the second set against the fourth seeds.

The 16-times grand slam champions have already guaranteed the year-end top ranking for the 10th time in the last 12 years and will cap another great year with victory on Sunday.
