ATP Challenger Tour Finals · 2012 →

The 2011 ATP Challenger Tour Finals was a tennis tournament played at the Ginásio do Ibirapuera in São Paulo, Brazil, between November 16 and November 20, 2011.^[1] It was the first edition of the event. The tournament was run by the Association of Tennis Professionals (ATP) and was part of the 2011 ATP Challenger Tour. The event took place on indoor hard courts. It served as the season ending championships for players on the ATP Challenger Tour. The seven best players of the season and a wild card awardee qualified for the event and were split into two groups of four. During this stage, players competed in a round robin format (meaning players played against all the other players in their group). The two players with the best results in each group progressed to the semifinals where the winners of a group faced the runners-up of the other group. This stage, however, was a knock out stage.^[1]
