hen serving, can I play it into my side wall and have it land in the correct opposite service box?
I’m guessing you can’t, but it doesn’t seem like an advantage if this was in the rules.
You can’t it doesn’t specifically say you can’t hit off wall but rules say the direction of the ball must be towards the box on the opposite side diagonally
You can’t, the rule does say that you have to hit the ball and then it has to bounce inside the service box across the court so by bouncing in the glass first this wouldn’t follow the rules
Ball hitting your glass before it bounces on the diagonal service box, is a fault, just like it is a fault when it hits your opponents' glass before it bounces in the diagonal service box.
