New York - Frenchmen and Pierre-Hugues Herbert won the US Open men's doubles crown on Saturday with a 6-4, 6-4 victory over Britain's Jamie Murray and Australian John Peers.
Mahut and Herbert became the first all-French duo to capture a US Open men's doubles title. It was also their first Grand Slam men's doubles crown.
They were Australian Open runners-up earlier this year while Murray and Peers suffered another near miss, having lost the Wimbledon final in July.
The French duo had won their only prior meeting with Murray and Peers in a 's-Hertogenbosch semi-final earlier this year.
Herbert was 0-4 at Slams before teaming up with Mahut at this year's Australian Open and they are 14-3 since.
Both Mahut and Herbert reached an ATP singles final this year as a qualifier, Herbert losing at Winston-Salem and Mahut winning at 's-Hertogenbosch.
Murray, the brother of former singles champion Andy Murray, was 9-23 in majors before partnering with Peers at the 2013 French Open and they have gone 23-10 since.
Other than US siblings Bob and Mike Bryan, Murray and Peers are the first team since Daniel Nestor and Nenad Zimonjic to reach consecutive Slam men's doubles final since the 2010 French Open.
