WTN lookup now available on ITF's site with additional features

After many e-mails from the USTA about it, the ITF World Tennis Number (WTN) was rolled out on usta.com about a month ago, and today I got an e-mail that it is now available on the ITF's worldtennisnumber.com site.

The player search page has a footnote that it is currently only showing USTA players.  I'm not sure why this is as the LTA launched WTN about six months ago so you'd think those players could be available too, but at least for now they aren't.

The search is interesting in that it seemingly only lets you search by surname (last name) or a tennis ID.  The type ahead last name search isn't terribly useful as there are often many players with the same last name and the player you are looking for may not be in the four they show.  So you have to finish your search and get the full list which can then be filtered by gender, country, and singles or doubles WTN.  This is an interesting way to search as if you knew the WTN, you probably wouldn't be looking!

But you can put in a range and narrow it down and presumably find who you are after, at which point you can click on them and get a page that is similarly branded to what the USTA sites shows, but with more detail!  The same animated WTN widget is there with singles and doubles WTN and Game zONe numbers, but on the overview page you additionally get:

  • Match activity with a count of unique singles opponents, average singles interval, and average doubles interval
  • Rating range that can show the range for singles and doubles for all time or the past year
  • A chart of "player tournament matches" showing the count of wins and losses by month, filterable by singles or doubles, although it does appear to include USTA League matches too, not just tournaments
  • A results summary with the win-loss record which can be filtered by singles/doubles/both and different time periods

Based on the results summary, it does appear it includes matches, for me at least, that were played in 2016, so I'm guessing that is roughly when the data starts the USTA provided to the ITF, which is consistent with what we've seen/heard elsewhere.  In fact, one can go to the Results tab and there, the date filter goes back to July 1st, 2016 so that appears to be the start date for WTN.

The Results tab is also where you can see more details with the specific matches including the players, their WTN, and the score.  They are actually grouped by event/league which is kind of nice, but oddly had a a stray match that wasn't in the right league.  The WTN shown does seem to be the WTN at the time of the match, so you can see how it changes.

Then there is a Head to Head tab where you can search for another player and see a head to head comparison of WTN ratings and if they've played, the records.  It seems to only do this for singles matches though so you can't find your stats with a partner or against a doubles opponent.  It will also show competitors in common which may be useful if you are scouting a future opponent.

All in all it is a nice presentation and it does provide more information than the USTA's site does and adds some additional useful context to help understand more about your WTN and playing history.

  1. Just looking briefly, you can type in full name(first and last) into the search and you'll get all players by that name listed, which is better than just getting every player listed by a last name. No idea why they say to search by last name or ID only.

  2. I’m missing match results from earlier this summer (probably close to when it went live). Curious if anyone else is noticing the same.

  3. It is nice that the doubles rating is so much more accurate than the UTR doubles rating! In UTR they tie your doubles rating so closely to the singles rating that doubles players that have won national tournaments can never be more than around 1 UTR point higher than their singles UTR even though in singles they can only win a few rounds. WTN seems much more accurate. Any word on when they will enable you to sort and rank by WTN?
