How many players were bumped up in 2017?

Part 5, USTA Adult Tennis League Stats, 2017

Every USTA tennis league season players seem to anticipate year end NTRP ratings level changes. Let's see how many players were bumped up or bumped down in 2017.

tennis league stats

About 44,000 players of the 300,000 that played in 2017 had a rating change - either a bump up to a higher NTRP level or a bump down to a lower level. This is about 15% of all players.

Now let's see how many players moved up and down, and whether anyone moved more than one NTRP rating level.

tennis league stats

The graph shows how many players were bumped up or down by how-many levels. For example, the "-1 " means a player dropped one level. This could have been, for example, from 4.0 down to 3.5, or 3.5 down to 3.0.

Several things stand out. About twice as many player went up one level than went down one level. Does this mean there is rating level inflation? Or that players gets better over time?

It's interesting to see that 700 players were bumped up 2 levels but that only 35 went down 2 levels. Next week we'll look into how many bumped up players were self rated.

We'll also look at whether some Sections have more than their fair share of level changes.

Where do you rank in USTA matches played?

Part 4, USTA Adult Tennis League by the Numbers, 2017

We've had several questions along the lines of "Where does my number of matches played rank?" This post will focus on this one question.

tennis league stats

This might look complicated but it's really very simple.

To answer the question, "Where do I rank?", count or estimate the number of USTA league matches you played in 2017. Then look across the bottom for your number. Then follow the bar straight up to see what percentile you're in. The percentile is the number on the left side.

For example, if you played 9 matches, you are in the 53rd percentile, which means you played more matches then about half of all USTA League players. If you played 20 matches, you are in the 83rd percentile. To rank in the top 10%, you need to have played 27 matches.

And to be a One Percenter requires that you played 54 USTA tennis league matches. About 3,000 players did this. It would be nice if the USTA gave those players recognition. I don't know if they will, but Tennis League Analytics will give the first 10 One Percenters who contact us before February 21 a free Player Strength Rating Report.

By the way, the chart does not show the 700 players that played more than 70 matches. Just image that the Matches Played numbers at the bottom keep going to 223 and the bars are all pegged at 100%. If you want to see how many matches the top 30 players played, look at the previous post.

We'll keep it short today. We will continue these types of posts throughout February. Email your questions or contact us via Twitter or Facebook.

Who plays the most USTA Matches?

Part 3 in USTA Adult Tennis League by the Numbers, 2017

Last week we were asked, "What's the most number of matches played by one player?" So in part 3 of USTA Adult Tennis League by the Numbers we'll answer this by section and nationally.

Previous posts in this series showed that about 300,000 adults played USTA league matches in 2017. The average number of league matches played: 12.4.

Let's see how the average number of matches differs by USTA Section.

tennis league stats

The Northern, No. California, and Southwest Sections lead the way with the highest average number of matches played by adult USTA player. At first glance, Northern at number 1 seems surprising. The weather is not conducive to year-round tennis. Northern is a small section. You can see this in a USTA section map from our June 18, 2017 post here.

Because Northern is small relative to the other sections, its average can be influenced by a few players that play a lot. The median may be a better indicator. The median is the number in the middle - half the players played fewer, and half played more. Let's see.

tennis league stats

The median for Northern is smaller than its average, but the same is true for all the sections by 2 to 5 games. This means that the average is pulled up by some players that play a lot of matches. Let's see the largest number of matches played by one player in each section.

tennis league stats

This is impressive. The most matches played by one player in each section ranges from approximately 75 to 225. Wow. Let's look at the top 30 number of matches played by one player.

Top 30 Number of Matches Played
NTRP Section Matches Played
4.0 southern 223
4.0 southern 193
3.0 southern 166
3.5 southern 158
3.5 southern 158
3.5 southern 158
3.0 southern 152
3.5 mid atlantic 151
3.5 southern 141
4.0 mid atlantic 140
4.0 mid atlantic 140
3.5 southern 134
3.5 southern 133
3.5 southern 130
4.0 southern 129
3.5 florida 128
4.0 no. california 127
4.0 mid atlantic 126
4.0 southern 125
3.5 mid atlantic 124
3.5 eastern 123
4.0 southern 121

4.0 southern 115
3.0 southern 115
4.0 southern 114
3.5 southern 113
3.5 southern 112

Which turns out to be:

Section Count
Southern 20
Mid Atlantic 7
Eastern 1
Florida 1
No. California 1

USTA Adult Tennis League 2017 by the Numbers, Part 2

How many players are in each NTRP Level?

This is the second installment of our blog series on interesting USTA tennis league statistics from 2017.

Let's look at how many of the approximately 300,000 adult league players were in each NTRP level at the end of 2017.

tennis league stats

You might notice a few curious things in this chart. What's with the NTRP Rating of 0.0? We researched this and it appears that the USTA assigns a 0.0 NTRP rating to players who have not played enough matches to keep a Computer rating. Those players must self-rate for the new season. In this case, for the 2018 Season. The USTA has a FAQ page about these types of things here though the 0.0 Level is not explicitly mentioned.

There are no league players at 1.0 or 1.5. And while 6.0, 6.5, and 7.0 appear empty, there are, respectively, twelve, six, and nine players at those levels.

In terms of percentages, here's an easy way to look at the numbers:

Percent of USTA Adult League Players by NTRP, Year-End 2017

Ignoring the NTRP 0.0 Level

NTRP Group        Percentage
3.0 and below 31%
3.5 34%
4.0 and above 37%

Roughly, one-third below NTRP 3.5, one-third at 3.5, and one-third above 3.5.

A 4.0 player is in the top 37% of players. A 4.5, top 11%. And a 5.0, top 2%.

USTA Tennis League 2017 in Review, Part 1

2017 By the Numbers

In 2018 Tennis League Analytics will again cover USTA Adult League Championship events and blog about the strongest teams by flights. Until then we'll look at interesting 2017 USTA League numbers.

Almost 300,000 tennis players participated in USTA league matches in 2017, which is about 12,000 more than in the previous year. The chart below compares 2016 to 2017 by Section. USTA Southern really stands out not just because of their sheer size but also because of their growth. WOW!

And would you have guessed that the next largest USTA section by players is the Midwest?

tennis league stats

To see what these numbers look like on a USTA section map, check out the three maps that Tennis League Analytics posted last July - they appear on our blog archive here. The USTA section maps show counts that combine 2014 to 2017, but the proportions are similar to 2017's numbers.

These 300,000 USTA Tennis League Players competed in about 1.25 million USTA League matches. The next chart shows the split of singles versus doubles. About three doubles were played for every singles match.

tennis league stats

The average number of matches played by a 2017 USTA Adult League player:     12.4. How many did you play?

We'll continue to look at more stats next time. Do you have interesting question?

How about the top-ten list of most matches played by a player? Statistics by gender? How many players were bumped-up? Were any players bumped up by more than one NTRP rating level? Which USTA Section has the highest average rating?
