Ma Long's Serve and Other Top Ten Players
In my blog on Nov. 24, I pointed out how blatantly illegal world champion Ma Long's serve was, and in particular how he illegally hid it with his head so the opponent couldn't see contact. (Here's the five-picture sequence.) This is now mostly the norm at the world-class level. However, since that time several questions keep coming up, both in online forums and via email. Specifically, some have argued:
- This was a fast, down-the-line serve, and so isn't his normal serve, and so doesn't show that he hides his serve normally.
- That he only occasionally hides his serve.
- That when he hides his serve, he usually does it with his arm, not his head.
So let's look at the video and see what's really happening. For this, we'll use the video of the Men's Singles Final (12:47, with time between points removed) earlier this year when he became World Champion. We'll only use pictures and video in the three games where he's on the far side (where it can be clearly seen). The video sometimes zooms in from the side when he's serving, and so you can't see clearly if he's hiding the serve on those point, so I've skipped those serves. In the end, there were exactly 21 serves on the far side where you could see whether he was hiding the ball or not. Below are links to all 21, both the video and a still image.
So what do we learn by watching the video?
