Girl 16s Junior Match Analytics 2.17.2019

Every week now I’m going to be featuring a junior tournament tennis match and breaking down the data to reveal the tactical and strategic plans implemented by my player.

As our coaching team across the globe continue to analyze and map data from Junior match play (ages 10-18), the number 2 and the number 3 are the most popular shot rally lengths.  Analyzing the data with players on the court before practice is essential to leading a player to understand how to capture and keep momentum from point to point.  Even breaking the points down to controlling momentum shot to shot!

This match features two players ranked in the top 100 of North Carolina Juniors, Girls 16s division.

In this match, we see 3/4 points ending 0-4 shots, this data continues to resonate how important the First Strike 2-shot sequences (pattern + combination) are in match play.  Player’s who become familiar with the Top 7 S/S1 and R/R1 Serve, Forehand, and Backhand combinations, the more likely they will succeed in executing them in match situations.

Next, a look at the Win% in each of the Rally Length Categories, knowing the rally length of each category is the first piece of information to educate your players and reverse engineer your practice.  The win percentage is another important metric to analyze with your player, the goal to achieve is winning 55% of the total points in a match.  Here’s the breakdown from this match.

Even though Oliver only wins 43% in the First Strike phase of the point, she did win the points 0-4 when it counted the most, as well as dominating in the next 2 phases of the point, the Patterns of Play phase (5-8) at 72% and Extended Rally phase (+9) at 92%.  Overall Oliver hits the magic number of 55% total points won for the match.

The Rally Length Win/Loss Ratio Chart shows that Oliver did a better job this week managing the S/S1 First Strike phase.  She still struggled this week on the S1 after hitting a 1st Serve and Return after receiving a 1st Serve, so back to the practice court this week to improve her First Serve Return %.

As you can see in the chart above, the errors are occurring after hitting 1st Serves or receiving 1st Serves.  We visited the areas on the practice court the week after this match and found that with the S1, the reset movement after the Serve needed to be sharper.  Also, the 1st Serve Returns needed to be struck more precise deep and down the middle third of the court.

 

Now we move on to the Momentum Flow Charts for each Set and Tiebreakers.  The Momentum Scoring System Chart is also helpful for a player to recognize how many Momentum and Conversion Points are being won or lost.

The point is the object of momentum in tennis.

In this 1st Set of the match, the difference was in the number of momentum points that Oliver won vs. Jones.

Jones won the 2nd Set 4-6.  Below is Momentum Flow Chart for the 3rd Set Tiebreaker, Oliver won 10-8.

The 3rd Set Tiebreaker is a perfect example of how Conversion Points (winning 3 points in a row) are weighted more than Momentum (winning 2 points in a row) Points.

  1. I like very much that you want to use data from the match to analyze the performance and to set new goals to improve your player.
    My comment is that it is confusing for me to read…you use S0,S1,S2,S3, etc. also the same for the Return…
    Could it not be simplified? shot 1, 2,3,4 (shot 1 or ball 1 is always the serve and shot 2 or ball 2 is always the return, shot 3 is always the S+1, shot 4 is always the R+1, etc.?

    1. Yes, S1 – the 1st Shot after the Serve, R1- the 1st Shot after the Return. The reason for using this logic is to have the player understand that the Serve and Return are not ground strokes and are differentiated from all other shots. The system can be easily understood when explained in this context. You can read other articles on my blog that explain more, for example the articles on the 2016 Orange Bowl Jr Championships
