If one evaluates the performances of the ATP top according to different surfaces, there are discrepancies to the actual evaluation especially on grass.
The new (self-)understanding between Rafael Nadal and Roger Federer will not be torn apart by a closer look at the points achieved this year on various surfaces: Federer is the number one twice (on hardcourt with 5005 points, on lawn with 2500 points), Nadal naturally leads the ranking on ashes (4680 points) – and is his Swiss rival on hard ground after the US.Almost fraternal sharing.
The year 2017 is of course one of the special circumstances, mainly due to the longer-term absence of two players who have dominated the tour over the past few years: Novak Djokovic and Andy Murray.The Serbian has at least achieved a fifth place in the fictitious annual ranking in his few performances on sand, Murray doesn’t have a green branch in any category.Stan Wawrinka could have made a difference on hard ground, but the three-time major champion lets the work rest just as much as Kei Nishikori.
Alexander Zverev is a pattern of constancy: German number one is ranked fourth on both Ash (1575) and Hard (2165) – which corresponds to his current ranking in the ATP world ranking.On both surfaces, Zverev has won a Masters-1000 title, in Rome on sand and in Montréal on faster runs.
Dominic Thiem has impressively underpinned his position as the second-best player on the Terre Battue (2570 points), but in the hard court ranking, the Lichtenwörther would fall out of the top ten with 1055 points.
Least agreement with the “real” conditions prevails on grass, especially because of the few tournaments: Wimbledon finalist Marin Cilic (1590) is behind Federer, followed by Tomas Berdych (855) and US-American Sam Querrey 810), who eliminated the defending champion for the second time in a row on Church Road: 2016 Novak Djokovic, 2017.
