The fifth day of the 2012 ATP World Finals presented the tennis world with a slate of marquee matchups, including two round-robin matches featuring four of the Top Seven men's singles players in the world.
Though in each of the two singles matches, the higher seed won, for the two perceived underdogs, the losses represent lost opportunities to build confidence with victories over marquee opponents.
Here are the scores from Day 5 matches at the O2 Arena in London, England.
(1) Novak Djokovic def. (5) Tomas Berdych; 6-2, 7-6 (6)
(3) Andy Murray def. (7) Jo-Wilfried Tsonga; 6-2, 7-6 (3)
(5) Mahesh Bhupathi and Rohan Bopanna def. (2) Max Mirnyi and Daniel Nestor; 7-6 (5), 6-7 (5), 10-5
(4) Robert Lindstedt and Horia Tecau def. (8) Jonathan Marray and Frederik Nielsen; 6-3, 7-5
After another slate of star-studded matches, here are some of the players who underperformed on Friday, and will be disappointed with their showings at the 2012 ATP World Finals.
All year long, Jo-Wilfried Tsonga has appeared to be on the verge of taking the next step in his career, and win a major title, or even an Olympic singles medal, but despite reaching the Semifinals at Wimbledon and the French Open, the big Frenchman has failed to win a signature title.
At the ATP World Finals, Tsonga was even more disappointing, as he dropped all three of his round-robin matches, culminating with a lopsided loss to Andy Murray on Friday.
He was hopeful heading into the tournament, as he reached the finals at last year's edition of the event, but the world No. 8 will have to wait a little bit longer to take home his first major championship.
Max Mirnyi and Daniel Nestor
As the No. 2 seeded doubles pairing in the field and the reigning ATP World Finals champions, Max Mirnyi and Daniel Nestor entered the 2012 tournament with aspirations of repeating, but they struggled mightily during the Group Stage.
As the top-ranked team in Group B, Mirnyi and Nestor lost twice and wound up third in the final group standings, meaning that last year's champions won't even advance beyond the round-robin phase of the tournament.
