Roger Federer seems quite determined to end a marvelous season on a high note. Ranked second in the world, he has no chance to surpass Nadal by the end of the year but instead, he can add up another beautiful chapter to a perfectly written book the season of 2017 can be reduced at. Moreover, a Winning Streak that started last month at Shanghai Rolex Masters is still in place with Federer having won 12 matches in a row. Beating up Alexander Zverev in yesterday's highlight, the Swiss tennis legend secured a spot in for the Nitto Atp Finals semis.

Fifteen years ago, as the season of 2002 was about to end, Roger Federer made his debut at the year's ending tennis show.

He only made it to the semis and last night he reached the same spot for the 14th time in his career. Basically, he has made one single wrong step and that was in 2008 when he failed to qaulify from the group stages.

Federer makes no wrong moves in London

Returning to London after skipping last year's edition ( the only tie he did so since he made his debut at the ATP Finals), Federer scored a first compelling win over Jack Sock, a firt timer at O2 Arena in London. The second session put the 19-times Grand Slam winner in the same fighting box with the NextGen leader Alexander Zverev. Ranked third in the world, the 20-year-old German turned out to be a difficult rock to crack. Serving brutally well in the key moments, Federer was able to run away with the opening despite trailing by 4-0 in the tie-break.

The second set saw Zverev recovering after a sloppy start to keep the pressure on Federer's shoulders. Eventually, it paid off with Federer being hesitant on his serve. The German won the second act by 7-5 and a third decisive set's certainty brough in a dramatic feeling. It wasn't the case though as the all-wise Federer dismantled Zverev's forehand side piece by piece to secuer an easy win by 6-1.

Roger Federer can see the finish line

A six-time winner of the ATP Finals, Roger Federer hasn't won it since 2011. In the meantime, he lost three finals, all to Novak Djokovic. Now, the coast seems rather clear with his biggest threat Rafael Nadal out of the contest with a knee injury. The third matc of the Roud Robin stages will put Marin Cilic on the other side.

The Croatian looks like an easy target as he has already been eliminateed from the tournament.

The semis means that Federer is likely to cross swords with the second place's occupant from the other group. Grigor Dimitrov cruised past David Goffin earlier today which makes himm the porbale winner of the group. He and Federer are on a collision course for the final.
