 Hey and welcome to one minute tennis lessons with the tennis mentor. When playing doubles you and your partner are responsible for covering around 50% of the court. Lots of players assume that that 50% is divided between a line down the centre of the court. However you're going to be more effective if you split that court into diagonally. These players are going to struggle when they're picking up a much shorter ball or covering the lob. This player at the net will also be afraid of intercepting and taking some of their partner's shots. If you split the court this way this player is going to have a much better chance at picking up a drop shot that lands here and this player is going to have a much better chance at covering the lob. This player will also be more confident when looking to intercept and it's going to be much easier for them to cover all of the court.
