Murray makes short work of Wawrinka

It was also confirmed that Jamie Murray and Brazilian partner Bruno Soares would end the year as the world’s top-ranked duo, courtesy of a defeat for rivals Nicolas Mahut and Pierre-Hugues Herbert. 

Jamie has made a habit of beating his higher-profile brother to milestones. 

He won a Grand Slam title - the 2007 Wimbledon mixed doubles - five years before Andy won the US Open. 

Jamie reached number one in the ATP doubles rankings in April, seven months before Andy hit the singles summit. 

Now he has clinched the yearend top spot for the first time with Soares, a few days before Andy can match him and confirm he is the top dog in men’s tennis. 

Murray junior will meet Serb Djokovic in the final when not just the title but the year-end number one ranking would be up for grabs.
