Is there a viable alternative to the overhand serve?
I, like many, have shoulder pain with the overhand serve. It's been a long term problem, and I've rested it before, but overhand serving just hurts, even if I haven't hit on it for months. No other aspect of the game is painful, and I'm wondering if there is some alternative to the overhand serve (without an underhand serve).
I suppose the only possible alternative to this is a type of sidearm serve. Has anyone seen this used?
