The process to make varsity is very similar to making any other team whether it be a JV team, summer team or a college team. First the team has wants, needs, and requirements that influence the way the coach selects his team. (you say there is a need for a second baseman and pitchers). Secondly you must have enough talent and ability to influence the coach to “pick” you as a member of his varsity team. Thirdly the coach needs to be aware of you, your talent and your desire to compete at the varsity level.
Here are the things you can control:
You can control your talent/ability with your work ethic toward being the best you can be. This is no small task and one could write a book about all the things you can do to improve in this area. The list might include lessons, camps, selecting the right summer teams, diet, physical workouts, “T” work, batting cages, fungo drills, thera bands, long toss and the list goes on.
Get your name out to the coach so he knows who you are. This might be accomplished by attending a camp at the high school (if they have one) or just dropping in the coach’s office (or ask to talk to him after class). You can explain you’re really looking forward to playing varsity baseball and would like to know what he might suggest you can do between now and tryouts. He might suggest a summer team or an instructor --- who know. He may not have any suggestions but at least when you leave his office he will know who you are and that you want the job.
Keep us posted.
