Opponent grazed the ball just as it hit endline. That ball was going to leave the table. Still, ML had a boatload of spin on it. It's all about racket acelleration, contacting the ball at the right height, + getting the first bounce right. Too many people do not contact the bottom of the ball, so they have too much forward speed to make the ball come back, or even land short. It takes timing and good racket speed to make it work. You get this through loose muscles and a lot of training. No one will get it all together in one day just starting out at the newb stage. Excellent timing and racket acelleration are the keys. You can experiment with different heights and blade direction at impact. If you impact the ball below the net, you need to hit slightly forward of bottom or lift upwards during the swing and make the first bounce closer to the net than if you impacted it higher height. This lets you make the ghost serve extreme short and low over net. This takes the most training to get right. It is way easier to impact the ball above net height to make it short and ghost back to net, but it is infinately easier to flick this serve, because it bounces higher.
