At 9 and 10, the overhand throw becomes a repeatable machine. The grip gets found by feel without looking, the feet learn to flow INTO the throw with a shuffle toward the target, and accuracy gets measured with ladders and streaks. The glove-to-hand exchange starts its career too, and in softball it matters even sooner than in baseball: sixty-foot bases mean the infield clock is genuinely faster.
This session runs about 45 minutes at thirty to fifty feet. One idea becomes furniture: throws aim at the CHEST, always, because chest-high is catchable and everything else is an adventure. Arm care stays simple: warm up throwing before throwing hard, and any arm pain means stop, at every age.

Sixty-foot bases: runners arrive a beat sooner than on a baseball diamond, so infield outs are won in the glove-to-hand half-second even at 10U. Quick-catch counts, logged monthly, are the most predictive backyard number for infield playing time.
Gently steer toward over-the-top-ish at this age: it is more accurate, easier on the arm, and the base every position builds from. (Infielders add lower slots later, on purpose, for speed.) The fix is usually the FEET: a proper sideways turn and step makes the arm slot rise on its own.
Informally, yes: some comfortable stretched-out arcing throws at the end of catch build arm strength safely, at this age and up. Structured programs come later. Warm before far, easy effort, and any arm pain ends the day.
