BOF,
Depends on whether the player is a starting pitcher but seems he is needed in relief. Which is ok, to go from third to relief but to pitch and throw again a few hours later? That's ok though if you all feel comfortable with that. But I am not sure that grimages does or he wouldn't have asked that question, he'd leave it up to the coach. I am sure it all depends on the scenerio. He might get lucky and just throw 9 pitches.
I commented originally because there was a concern about ice, which seemed silly to me because there was no concern about the above scenerio? You are trusting that coach knows what he is doing putting him in after he pitches but not sure he knows about icing?
No other person to play third? How do you know how much he will throw in a game? I am not going to get into this discussion much further, but IMO, it's so easy to see why so many young players suffer with arm/shoulder issues.
Pre season (?) tourneys are good, it gives everyone a chance to play. Common sense is that you ease into your season. But for most parents and players, it's more important not to waste a single moment on the bench. JMO.
