Federer & Djokovic Lead Indoor Performers At The Nitto ATP Finals

The FedEx ATP Performance Zone provides insight into the success of the London competitors indoors

The Nitto ATP Finals is the world’s most prestigious tennis tournament, with the top eight players battling it out for the trophy at the season finale. But since they will be playing inside The O2, which of the octet has been most successful indoors in their career?

Three members of the field have previously lifted the Nitto ATP Finals trophy, but nobody competing has won as many matches or at a higher rate than Roger Federer. The Swiss superstar tops the active leaderboard in both categories.

Federer could potentially earn his 300th tour-level victory indoors next week in London. He holds a 296-68 record indoors, having won more than 81 per cent of his matches. No other active player has 150 wins indoors.

The 38-year-old has captured 26 ATP Tour trophies indoors, which ranks fifth in the Open Era. The nearest active player on the list is Andy Murray, who has 15. Federer holds the record for most titles at this event with six.

"You’ve got to be sharp, I think,” Federer said last year. “You’ve got to be explosive. You’ve got to be quick in your decision-making.

“Playing aggressive and playing forward and taking charge of the point is definitely what you should be doing indoors.”

 Player  Indoor Record  Indoor Winning Percentage  Indoor Titles
 1. Roger Federer  296-68  81.3%  26
 2. Novak Djokovic  148-40  78.7%  13
 3. Daniil Medvedev  40-18  69.0%  2
 4. Rafael Nadal  82-37  68.9%  3
 5. Stefanos Tsitsipas  27-14  65.9%  2
 6. Alexander Zverev  40-26  60.6%  3
 7. Dominic Thiem  46-33  58.2%  2
 8. Matteo Berrettini  9-7  56.3%  0

But Djokovic, a five-time champion, is not far behind. The Serbian ranks second in the field in both wins and winning percentage indoors. The 32-year-old owns a 148-40 record, emerging victorious 78.7 per cent of the time.

Federer and Nadal have distanced themselves from the pack in this category, according to the FedEx ATP Performance Zone. Nobody else playing in these Nitto ATP Finals has won more than 70 per cent of their indoor matches. The closest is Daniil Medvedev, who has used his indoor success over the past couple of years to propel him into the Top 5 of the ATP Rankings.

Medvedev, who has won 69 per cent of his indoor matches, has the best record indoors this year with a 12-2 mark. The Russian has lifted three of his seven ATP Tour trophies under a roof, with all of those triumphs coming in the past two years.

World No. 1 Rafael Nadal is right behind Medvedev, having won 68.9 per cent of his indoor matches. The Spaniard, who holds an 82-37 indoor record, will hope to play his best at The O2 as he battles Novak Djokovic for the year-end No. 1 ATP Ranking. Winning two round-robin matches and then advancing to the final would guarantee the lefty accomplishes the feat for the fifth time, tying Djokovic, Federer and Jimmy Connors for second all-time.

Stefanos Tsitsipas ranks fifth among 2019 Nitto ATP Finals competitors having won just short of 66 per cent of his indoor matches, and reigning season finale champion Alexander Zverev is sixth with a 60.6 winning percentage.

Rounding out the London field are Dominic Thiem, who has won more than 58 per cent of his indoor matches, and first-time qualifier Matteo Berrettini at over 56 per cent.
