American pair Mike Bryan and Jack Sock have saved a match point in the deciding tiebreaker to beat Pierre-Hughes Herbert and Nicolas Mahut 5-7, 6-1, 13-11 for their first ATP Finals doubles title together.
Having failed to take advantage of five championship points during the tiebreaker, Bryan and Sock then had to save one against their French opponents before finally closing out victory on Sunday.
The 40-year-old Bryan has now won the season-ending tournament five times. He won four times with his usual partner and brother Bob, who has been out with an injured hip since May.
Sock and Bryan have dominated since teaming up, winning Wimbledon and the US Open before finishing their season in style in London.
The French duo’s season is not over yet. Herbert and Mahut are part of their nation’s squad for the Davis Cup final against Croatia, which starts in Lille on Friday.
