The first real ladder game against a 5.0 player

What happens today (fact)

  • This is my third ladder match at Milton tennis club.  My opponent is Andrew.  He ranked two spot(#2) above me(#4). 
  • The weather wasn’t great.  We almost cancelled the match due to the rain earlier. Realizing our upcoming schedule might not fit for another match, both of us made effort to get to the court and finish the ladder match. 
  • The result is one-sided.  I lost by 1:6.   We chose to use the 6-game instead of the 8-game pro set due to the weather delay.  The game only lasted 25 minutes.
  • Total points played: 45.  I won 38% of them (17 of 45).
  • I served quite well today (88% first serve in) and had 5 service winners.  

My hot takes 

  • I lost today because I feel my opponent is the better player
  • I wasn’t able to match my opponent’s intensity & shot speed.  When feel pressured and rushed, my rallies were often short. This gave my opponents too many chances to move forward and attack inside out.  This momentum keeps going and I was in a hole 0-4 very quickly.
  • My word playing at Milton’s Court 1 (showroom court) is 0 for 3 so far.  (lost to Henry, Suriyan, and now Andrew)I should avoid playing at this court for important matches in the future 🙁
  • When holding break points twice, I chose to play defence and let my opponent dictate the points. This works with ppl with/below my level, not today. When losing those two precious games, I lost my momentum and  my confidence

My post-game analysis after watching the video from SwingVision- 

  • I lost today because I chose the wrong tactics – I played too safe and bet my opponents would beat himself with unforced errors.  In my experience, It never worked when playing against opponents with both skills & experience.
  • My defense wasn’t up to my standard.  There are a few times when Andrew started to attack inside-out, and my returning shots were immediately falling short.  That makes me an easy target to get “finished” , and this led to the quick drop of my confidence. 
  • Even though my service was solid, I wasn’t hitting enough on his backhand, particularly for my 2nd serve.  As a result, he can attack my 2nd serve with ease, and got 2 winners out of my first two service games.  That also led to me having doubt of my abilities in the match.

Next steps

  • In order to work on my aggressiveness, the slinger bag I bought a few months ago is suitable to work on “techniques”.  
  • Mental part would be more difficult – essentially how can I feel more “confident” to generate my own pace ?  I guess the only thing I can do is to play against players slightly above my skill level this summer. 

 

 

 

First outdoor game in 2022 season – my tennis journal #1

Finally, I am able to play my first outdoor game, recorded using my newest equipment fence cap (bought on Black Friday 2021). It is a pro-set game with Kevin – my doubles partner from Credit Valley Club Inter-county “B” team. We didn’t play very often recently, as he spent more time on doubles and I focused on singles match plays.

The game was played at Glen Abby community part upon my request. The weather is cloudy with mild wind conditions, 8 degrees celsius in early after. I believe this to be an ideal weather condition for tennis, but Kevin feels it is a bit too cold. He said the balls feel too hard with the cold temperate. My topspin heavy style neutralized the bad weather condition, as I usually don’t need to hit the ball perfectly to generate points.

For the actual scores, I won the 1st set 8:3 by winning the last 4 games straight. The 2nd set was much closer and ended with 1-1 when the times ran out (the total score for the 2nd set was 15-15).

My conditioning is still nowhere close to my peak level. If we have enough time to finish, the 2nd set would be a lot closer. Fatigue seems to impact me much more than Kevin.

What I like about my game today is I was able to hit 2 winners on the forehand cross-court, each with over 85km/h on the line. I don’t usually attack that angle on my previous matches

What is interesting is my backhand slice shots type % – only 28% slices. I used to only use slices on my backhand so this is definitely encouraging to see. It could also indicate Kevin didn’t attack my backhand with deep balls much.

2021 Tennis Journey Recap

2021 is a challenging year for me.  I am quite satisfied with the progress I have made with my tennis journey.  I believe I became a better tennis player overall with the technology I have been using.

If you have arrived here, I hope you are a tennis fan (not just a speculator) like me, who is curious to learn to adopt modern technology to improve and enjoy the game. Here are the three things I am aiming to help you achieve :

  • Get a better understanding of how to get the most value out of SwingVision
  • Learn some new tricks and avoid the pitfall I experienced
  • Be inspired to improve your own tennis

Tennis score tracking and exported data analysis with Apple Watch using Swing App

Tennis score tracking and exported data analysis with Apple Watch using Swing App

During the winter of 2018-2019, I was able to take my tennis tracking journey into a new level.  By now most of my tennis hitting partners are calling me a “data nerd”, clicking my watch like crazy during the game. But when I show them the stats after the game, they all (seem to be) impressed.

I did the following two new things in particular:

  1. Used the “Point by Point + ” score tracking in the Swing App to track all the points I have played. In total, I tracked 18 matches over the last 4 month, all of them were single matches and played in 1 hour.
  2. Exported the captured data into spreadsheets. By analyzing the data set, I was able to identify some of the limitations, as well as some opportunities to further enhance the analytics experience.

Before we dive in, if you are interested in knowing the tennis tracking tools and methodology, or a high-level overview, you can check my 1st blog post of this series: Tennis tracking after 18 month of usage. Or if you prefer to track drills instead of match, you can check out my last post on advanced tennis shots tracking.

Advanced Analytics with Swimming data from Apple Watch

Advanced Analytics with Swimming data from Apple Watch

This blog post is aiming to provide a step-by-step guide to perform advanced analytics on swimming data, captured by Apple watch.  Microsoft PowerBI and Python on Jupyter Notebook are the primary tools to prepare, analyze and visualize the data.

You will learn how to export the workout data efficiently to your PC, make necessary data transformation, and understand what metrics and dimensions are available.  Then I will walk you thru how to analyze the data to answer typical questions related to why certain behaviors happened.   You will then see my preliminary attempt to use advanced analytics tools to predict future swimming performance.

Most importantly, you will find quite a few reference articles related to this topic, hopefully fulfilling your intellectual curiosity.

It is also the #3 articles of a series, the previous articles can be found here:

#1: How to use Apple Watch to monitor and improve swim performance

#2: Improving swimming performance with Apple Watch(WatchOS 4)

Lessons learned from an unexpected doubles tournament

Lessons learned from an unexpected doubles tournament

Tennis is a big part of my personal life.  Playing competitive level matches since 2006, I have won a few tournaments in the “club” level.  Ironically, I have never played in a doubles tournament ( never a fan of doubles game, and often complain about not even getting sweaty), nor have I played in a game organized by the companies I worked for (tennis might be such a “minority” sport that didn’t get much attention).

I broke both rules last week.

It was the 1st “3M Open” tennis tournament – featured only doubles matches. One of my colleagues in the lab signed me up for it.  We have played together a few times in the past but never played doubles as partners.  For both of us, the original goal was very clear –

“Enjoy the sunshine and have some fun. “

In the end, we brought the “3M cup” back home by winning three straight matches in a row. When I look back today, the experience was 100% memorable. But “fun” is not the appropriate word.  Instead, it is more of the mix of drama, pressure, heartbreak, teamwork, and a sense of relief.

Let me tell you why:
