The Murray brothers are trying to make being No.1 a family business, with older brother Jamie securing the top spot in the doubles team ranking while Andy leads the competition for the No. 1 singles ranking.
On Saturday, Andy Murray beat Milos Raonic in an epic three-setter, 5-7, 7-6 (5), 7-6 (11) to advance to the final.
Jamie and his doubles partner Bruno Soares will finish the season as the top doubles team, clinching their position when Nicholas Mahut and Pierre-Hugues Herbert dropped all three of their round robin matches in the ATP Tour Finals. In the individual doubles rankings, Mahut is No. 1, but Soares could move in front by winning the tournament. Jamie reached the individual doubles No. 1 ranking during the season.
