Looking back at Roger Federer's record 6 title triumphs at the ATP Finals
- Federer is the most successful player at the season-ending event, and each of his wins has been memorable.
4th title: 2007 Shanghai
Fernando González became the first player in 19 attempts to beat Federer in a group-stage match at the ATP Finals, but the Swiss maestro overcame the hiccup by topping the group following straight-sets wins over Nikolay Davydenko and Andy Roddick.
For the second year year in a row, Federer met Rafael Nadal in the semifinals following a loss in the Roland Garros final which denied the Swiss a calendar year Grand Slam. And for the second year in a row, Federer beat his nemesis in straight sets 6-4 6-1 for one of his most lopsided wins over the Spaniard in the duo's storied rivalry.
Federer beat another Spaniard David Ferrer in the final to lift his fourth title at the tournament in six appearances.
5th title: 2010 London
In his ninth appearance at the ATP Finals, Federer beat David Ferrer, Andy Murray and Robin Söderling in straight sets to reach his 8th semifinal at the tournament.
Federer beat Novak Djokovic in straight sets in the last-four to set up a title clash with his arch-rival Nadal.
In his third meeting with the Spaniard at the ATP Finals, Federer emerged victorious in three sets to equal Ivan Lendl and Pete Sampras' record of five triumphs at the tournament.
6th title: 2011 London
Making his 10th consecutive appearance at the season finale, Federer navigated through a group containing Jo-Wilfried Tsonga, Rafael Nadal and Mardy Fish to go 100% in group-stage play for the 7th time.
In a rematch of the 2007 final, Federer beat David Ferrer in straight sets in the semifinal to set up a title match with Jo-Wilfried Tsonga.
The Swiss maestro beat the Frenchman for the third time in as many weeks (2011 Paris final, 2011 ATP Finals round robin, 2011 ATP Finals final) to become the first player in tournament history to win 6 titles.
In the process, Federer also became the oldest player to triumph at the season finale.
