London, UK, 20 November 2015 | tennis.com.au

Bob and Mike Bryan have saved five match points to defeat John Peers and Jamie Murray at the ATP World Tour Finals in London.

The win, which came in the final round-robin match of Group Ashe/Smith, secured the American twins a semifinal berth.

Peers and Murray led 5-3 in the second set tiebreak after having won the first set, but eventually fell 6-7(5) 7-6(5) [16-14].

A win would have seen the Aussie and the Brit advance to the final four in London.

Instead, their maiden campaign at the season-ending event has come to an end.
