It may or may not be to late, but look into a winter camp at the school/schools your interested in. Call each camp to see which coaches are there to maybe help at the camp, usually high school coaches, but a possible source for networking. My son attended a winter camp a few years ago, and the next year, a recruiting coach from a D3 school contacted him. You never know who is watching!!
Look into a Perfect Game event, or other showcase venue which might be held indoors in your area. I know we have a few of those in our Chicago area. Do some research.
Ask your high school coach about college contacts he may have. It may not be at a particular college of interest right now, but who knows, maybe they might have your academic field of interest, and you could possible play baseball. Maybe you also need to consider a smaller school, like a D2 or D3. Do your research. You still have some time this spring. This is the time to work really hard for next season. Players are made in the off-season.
