At 9 and 10, the throw becomes a repeatable machine. The four-seam grip gets found without looking, the feet learn to move INTO the throw (a little shuffle gathering momentum toward the target), and accuracy gets measured with ladders and streaks. The exchange (glove to hand) starts its career here too, because infield play at every level is mostly how fast and cleanly that transfer happens.
This session runs about 45 minutes at thirty to fifty feet. One idea gets repeated until it is furniture: throws are aimed at the CHEST, always, everywhere, because chest-high is catchable and everything else is an adventure. Arm care stays simple at this age: warm up before throwing hard, and any arm pain means stop, at 9 exactly like at 19.

Because chest-high is the only universally catchable throw, and at 9 and 10 most errors in real games are throws, not catches. A kid who bores their catch partner with chest-after-chest is building the exact reputation infield coaches hand positions to.
The transfer from catch to throwing grip, done at the middle of the chest with the feet already moving. It matters immediately: quick-catch counts at this age predict infield playing time better than arm strength does, and the habit is pure volume, thirty seconds at a time.
Informally, yes: finishing catch with some comfortable stretched-out throws (fifty or sixty feet, arcing, easy) builds arm strength safely. Structured distance programs belong later. The everyday rules already cover it: warm before far, effort easy, and any arm pain ends the day.
