Tennis is different from everything else on this site, because there is no season table to keep. A tournament starts with a hundred and twenty-eight players and ends with one, in seven days, and then another one starts somewhere else.
Scores and draws
The section covers both tours, ATP and WTA, with results as matches finish and the draw laid out round by round. You can see who has gone through, who is out, and who a player meets next if they win, which is the question anyone following a tournament is actually asking.
The draw view is the useful part. A list of results tells you what happened; a bracket tells you what it means. Seeing that a seed has gone out on the other side of the draw changes how you read your own player, and that only shows up when the whole thing is on one page.
What is not here yet
There is no tennis simulator. A knockout bracket is the easiest thing on this site to simulate, and it is on the list, but it is not built, and saying otherwise on this page would be a lie. Until then the section does the reporting half well and does not pretend to do the other.
