I have been figuring out the ranking system in tennis recently. I took a look at the page for the 2017 Men's singles for the US Open.
It has the current ranking points for each player, how many points they are defending at the US Open and the minimum number of points they will end up on afterwards (assuming they play and lose one match).
However, one line I could not figure out was:
30 | Argentina | Diego Schwartzman | 1,280 | 10+90 | 10+45 | 1,235 | First round vs.
So, he is defending 10+90 points from last year. Last year Diego Schwartzman got knocked out in the first round and did not have to come through qualifying so should have gotten 10 points surely? Also it says his minimum for this year is 10+45 but surely it should be 10?
He is the only player listed like this (everyone else has 10 as their minimum ranking points) and I can't figure out where the 90 and 45 points come from.
