G.O.A.T.
This pushing tactic only works because they get shots that can be lobbed.
These guys used to give me trouble as well until I put in the effort to develop better footwork and a flat forehand drive which is also works to handle the short, soft sitters (those gave me trouble as well).
I hit a lot of hand toss shots - start near the service line, hand toss a high ball behind towards the service line, footwork to get into position, then drill a flat hard shot. To me, this has been much more effective than hitting against a ball machine.
Sadly I have the most difficulty with those shots due to shoulder surgery. I'm much better swinging low to high. Anything flatter tends to tweak my shoulder and risk dislocation. So I'll probably always be vulnerable to the lobber. But admittedly, they have to be a really good lobber to beat me these days.
