The semifinals at the Nitto ATP Finals are now set:
Roger Federer will face
Stefanos Tsitsipas while
Dominic Thiem versus
2018 champion Alexander Zverev. Both the World #1
Rafael Nadal and World #2
Novak Djokovic were eliminated via different paths in the last two days.
In a blockbuster showdown between Federer and Djokovic (their 49th career meeting) for the semifinal slot, Federer shocked Djokovic by defeating his rival in straight sets 6-4 6-3 to bring
their head to head of 23-26 in favor of Djokovic. Interestingly, the result of this match also decided the World #1 race for 2019. Nadal claimed his 5th yearly World #1 (2019, 2017, 2013, 2010, 2008), matching the other members of the trivalry: Djokovic (2018, 2015, 2014, 2012, 2011) and Federer (2009, 2007, 2006, 2005, 2004). The significance of the Federer-Djokovic match was set up after Dominic Thiem beat Djokovic in one of the best matches of the year: 6-7(5) 6-3 7-6(5). Thiem's victory meant that Djokovic wouldn't gain undefeated ranking points in the ATP Finals, thus making his task to reach the #1 spot that much more difficult.
In fact this year's ATP Finals was one of the most thrilling in years. In addition to Thiem-Djokovic and Federer-Djokovic there was another notable match in Medvedev-Nadal. Medvedev was up in the third set 1-5 3-40 on Nadal's serve and the Russian twice served for the match at 5-2 and 5-4 but eventually he lost in a third set tiebreak. Other important wins were Zverev's first win over Nadal and Tsitsipas's first win over Medvedev. In the end, despite winning two matches in the round robin round (both 3 set victories, against Medvedev and Tsitsipas) Nadal was eliminated when Zverev defeated Medvedev in straight sets, claiming the final semifinal slot to join Thiem, Federer and Tsitsipas.
MadProfessah's prediction: Federer d. Tsitsipas and Thiem d. Zverev.
