Murrays on top
Andy Murray and older brother Jamie became the first brothers to simultaneously occupy world number one spots when the year-end rankings were released on Monday.
Murray junior beat Novak Djokovic in the ATP World Tour Finals showdown on Sunday to retain his position on top of the ATP rankings charts.
It was a career-best 24th straight victory for the Scot and capped a fine year in which he won a second Wimbledon crown and defended his Olympic title in Rio.
Meanwhile, brother Jamie and partner Bruno Soares secured their place at the top of the doubles charts as French duo Pierre-Hugues Herbert and Nicolas Mahut were sent packing in their final round robin match on Friday.
Murray and Soares were subsequently defeated in their semifinal by South Africa's Raven Klaasen and American Rajeev Ram on Saturday.
