See the pitch from where it is released in games,I thought this was a good question and we have nothing?
Personally I got a net to hide behind sitting on bucket to throw to DD. Never really thought about pitch trechetery. Fair question and I do not know. Does it matter?
Glad I could help.
?Matching the trajectory is key. You have choices, sitting-standing and overhand-underhand. Other factors are accuracy and distance from the hitter. I usually prefer overhand, sitting.
