My son cannot raise his level of play in practice like he does in a game. This cost him a considerable amount of lost playing time last year as a pitcher. It was only after they put him in a game where they were getting clobbered and he shut down the other team that the coaches realized they had a pitcher that they could count on. He went on to be one of their starters for the rest of the season.
Fortunately, it is not an issue this year for pitching (yes, he still is not as good in practice as in a game), but it is still an issue with hitting which directly affects playing time for his other position.
Any ideas on how to raise the practice level? I'm useless because I had the same problem when I played competitive tennis. It isn't necessarily an intensity thing but dialing in for a game situation is so different than scrimmaging your own team.
