Canada's Daniel Nestor won his second consecutive Barclays ATP World Tour Finals doubles crown Sunday.
Third-seeded Nestor and Max Mirnyi of Belarus downed Mariusz Fyrtsenberg and Marcin Matkowski of Poland 7-5, 6-3 in the championship match in London, running his record in the ATP Finals to 32-19. He has won the title on four occasions.
Last year, Nestor and Nenad Zimonjic won the season-ending event.
Nestor and Mirnyi went unbeaten in the round-robin portion of the tournament to finish first in their group then got past the top-ranked Bryan brothers, Bob and Mike, in the semifinals.
In their first full season together, Nestor and Mirnyi won four ATP titles and finished with a 48-19 record.
Roger Federer of Switzerland won the men's title for a record sixth time with a 6-3, 6-7 (6-8), 6-3 win over Jo-Wilfried Tsonga. It was Federer's 39th win in the Tour Finals, tying him with Ivan Lendl for the most in a career.
