Just to chime in and back up what DC33 wrote, I am a high school coach on the North Shore. I hear the "it's all politics" BS all the time. Honestly, as high school coaches we usually have no clue who did or did not play travel ball--nor do we care. The program I coach in plays Sandburg every year. Sandburg is a fine program. I am sure the situation is the same there as it is up here. Any high school coach worth his salt (or interested in keeping his job for long) will do everything he can to take the best talent available, regardless of whether they played travel ball or not. Talent includes skill level, coachability, and character.
With that said, since it sounds like you will be an incoming freshman, you should consider finding a travel team to play for. Not because it is a lock into your HS team, but because the travel schedule will likely provide you with a pre-high school baseball experience that is more competitive than a house league. It does not have to be the OP Magic (although they are a fine organization)--there are many solid 14YO travel teams in your area. Hunt for one that fits you and will give you an opportunity to play--and hunt for one that is instructional based, and not overly concerned about winning.
The reason it seems that your area high school programs are littered with travel players is because the better players tend to gravitate toward them.
Follow DC33's advise--and most importantly, TAKE CARE OF YOUR GRADES. Good Luck!
