In Between Seasons: Looking Ahead To Baseball

Looking ahead to the baseball season, every winter I try to pick a facet of the game and look for ways I can improve on teaching it. This winter I'm going to focus on how we can improve our individual defensive fundamentals.
Our infielders need to be focused on consistently applying ground ball fundamentals. Practices need to be oriented to give them time everyday to field and make the throw on a variety of balls that they face in the game. Outfielders need to work on tracking a fly ball and getting into throwing position every time.I'm going to look for ideas on how to better teach those skills and get them to carry over into the game. I'm going to be looking for consistency in applying these skills. The whole defensive emphasis will be on preventing the unnecessary, the unnecessary extra base, the unnecessary extra out, the unnecessary extra run. Pretty standard stuff, but I believe you get what you emphasize and they're going to hear these points all spring.
Another emphasis that I want to take into the season is being mentally tough enough to play the game from pitch to pitch. Playing 3 or 4 innings that way is not good enough. It may be tough for some to accept, but the most talented players may not always be the most consistent players. We need consistent players on the field.

I'm always looking for ideas. Please comment and what you do that works well.
