"Warm-up" pitches for potentially injured F1

[Andy]

Here is the situation I had recently:

Hard hit ball up the middle hits the pitcher on the leg. Not life threatening, pitcher doesn't fall down or anything.

After the play is over, D coach asks to check on his pitcher...I tell him to go ahead and walk a discreet distance away.

I hear this exchange:

Coach: You OK?
Pitcher: Yes

Coach: Good, now here is how we want to pitch this next batter....
