The larger warm weather states have more prospects trying to play baseball in state than there are available roster spots. Players are more likely to leave these states looking for baseball opportunity than players coming in. The players who do come in from outside states usually are successful due to being top recruits. At Cal Poly it would mean being a potential baseball draft prospect. At Cal Tech it would mean being a top rocket scientist (JPL) prospect.
It’s not uncommon for baseball coaches to discourage majoring in engineering or other majors with afternoon labs and/or intensive homework. Unranked HA college programs tend to be more patient with engineering student. Even without engineering any college athlete taking academics very seriously will find baseball and academics are both full time jobs. Both of my kids were non engineering baseball/softball playing STEM majors. They didn’t have a lot of free time.
