position yourself better. (get in the correct recovery sports)
get faster and quicker
guess which way if you have to (like pros do returning serves)
hit deeper to give your opponent less angles
if you hit to the middle, you give him less angles, but then its easier for him to hit to either side.
if you hit crosscourt, he can hit more angled crosscourt, but you also give him a harder down the line shot.
if he pulls you out really wide, you can lob it to give you more time to recover.
also, if he pulls you out wide, its usually better to hit it back cross court to give him less open court to hit a winner
but hitting down the line works too sometimes
i hope this helped
