In his discussion of the value of stopping attacks in the left-hand corner of the padel court, Sandy focuses on the difficulties of taking on attacking slice smashes that have a lot of side spin. The height and revolutions of the ball determine whether or not to employ the double glass; players are more likely to come across low, revolving balls on the left side.
The video illustrates how to properly defend against viboras and bandejas while also setting yourself up for flatter or top-spin smashes. It all starts with remaining in position and being aware of which glass the ball contacts first.
Sandy emphasizes the value of repetition and confidence in this area, urging players to let the ball contact the glass in order to better analyze the rebound and develop their talents. For individuals who find this particular feature of padel tennis particularly difficult, the movie also contains a course on the walls.
