My son’s been throwing about 5-10 innings a week since March or April (whenever the weather started permitting). He played in 2 leagues, a spring and fall league. He’s pitched twice a week during league play (plus a little BP and practice) and about 3 or 4 times a week when the leagues weren’t going (usually 1 or 2 simulated innings or roughly 20-40 pitches a session).
Is it better in terms of injury prevention to throw less pitches more frequently or more pitches with more rest days in between? So far in terms of results this has been unbelievably good for him.
