As always after a Major, the ATP ranking list has seen some significant changes and shifts, with many losers and gainers ahead of the last stage of the season. The defending US Open champion Novak Djokovic failed to go all the way again in New York, retiring in the fourth round against Stan Wawrinka with shoulder problems and leaving the door wide open for his closest rival to seize the opportunity and reducing the gap at the top of the standings.
Rafael Nadal conquered the fourth US Open crown following a thrilling triumph over Daniil Medvedev in just under five hours, going two steps further than in 2018 and standing only 640 points behind Novak in the battle for the ATP throne.
Nadal is the only four-time champion on the Tour in 2019, claiming two Majors and two Masters 1000 events to lead the ATP Race, having nothing to defend in the rest of the year after ending 2018 season following that retirement at the US Open.
The pressure is on Novak who has caught Jimmy Connors' 268 weeks on the ATP throne, standing just two behind Ivan Lendl. The Serb will pass the Czech as well but he could lose the no. 1 position after Shanghai, having 1000 points to defend there.
Roger Federer lost in the quarter-final to Grigor Dimitrov in five sets, struggling with back pain in the deciding set and missing another chance to grab the first US Open crown since 2008, staying third on the list and far in front of the closest rivals.
Alexander Zverev or Dominic Thiem are not there anymore, with the Russian Daniil Medvedev becoming world no. 4 for the first time in a career after an incredible summer and 3100 points earned in the last four tournaments played after Wimbledon.
Despite tiredness and fatigue, Daniil gave his 120% in New York to advance into the first Grand Slam final, battling with Nadal like almost no one before after losing the opening two sets and failing to produce one of the most stunning comebacks in the Major title matches after running out of gas in the decider.
Medvedev is almost 700 points clear of Dominic Thiem who had to bow out from the US Open in the first round, still holding a nice lead over Alexander Zverev who had another Grand Slam tournament to forget. Stefanos Tsitsipas, Kei Nishikori, Karen Khachanov, Roberto Bautista Agut all Fabio Fognini suffered early exit in New York, staying ahead of the quarter-finalist Gael Monfils and the first-time Major semi-finalist Matteo Berrettini who gained 12 places to crack the top-15.
The quarter-finalists Diego Schwartzman and Stan Wawrinka are back inside the top-20, with John Isner barely staying in the top-20 after the third-round loss in front of the home fans. Grigor Dimitrov used a favorable draw to score four wins (one walkover) and reach the semis as the lowest-ranked player since Wimbledon 2008 and since 1991 at the US Open, returning into the top-25 for the first time since February and hoping for more of the same in the rest of the season.
Failing to compete at the US Open and losing a massive amount of points, Juan Martin del Potro is out from the top-70 for the first time in three years, working on a comeback after another knee injury and hoping to play a couple of tournaments before the end of the year.
Alexander Bublik, Soonwoo Kwon, Kamil Majchrzak, Dominik Koepfer, Tommy Paul and Gregoire Barrere are on a career-high ranking in the second top-100 group, with six new players in the elite in comparison to the previous ATP list. ATP Ranking list
