Roger Federer was convincingly involved in the ATP finals in London. On Sunday night, the Swiss backed 6: 7 (4), 3: 6 against Kay Nishikori in their first group encounter.
Statistics show that this is the first time in the glorious career of the Master, where it does not win a game in the finals of the final Masters. Until the previous night, only 6 were the losses of Federer in the groups, but in each case he was at least established.
The defeat of Nishikori is also the fifth consecutive tennis player of Federer. The last player of the "ten" that the Master was defeating was Grigor Dimitrov at the end of Rotterdam in February. The last time the Swiss entered a similar series of consecutive defeats against the top 10 players was in the 2013 season, when they lost 7.
Another curious fact: Federer's defeat on behalf of Nishikori guaranteed Rafael Nadal to end the year as No. 2 in the ranking.
