I actually had a conversation with an OHSAA representative on this very issue. You cannot practice with a non-school (travel) team if you are playing on a school-sponsored team. However, you can take lessons or practice on your own, as long as it is not part of the travel team practice, and you are not practicing as a team. You do not need to pay the instructor, as that would eliminate dad throwing bp to DD, or mom setting balls on a tee, or uncle hitting pop-flys. There is no requirement that you pay your instructor. And, you can have multiple players getting individual instruction at once, as 5 girls all taking "hitting lessons" at the same time. From my conversation, I believe it is totally within the rules to have multiple girls getting hitting lessons at the same time, but you cannot take infield practice. However, you could work on "fielding practice" as well if it is instructional, and not a team activity. That is why the rule is so archaic. The line is too easy to blur. You could have your entire travel team show up for "hitting instruction", and as long as you don't do it as a "team activity", you would be within the rules. Doesn't that sound somewhat ridiculous? As for my team, I have one player that is on a school-sponsored team this year. She is going to show up and get her hitting instruction, but not participate in conditioning or infield. She will also get work on her catching and throwing, but as an individual, and not with the rest of the team. I'm not sure how this makes a difference, but we are going to abide by the rules.
