Are certain majors harder to get into?

My son wants to study sports business at ASU. We are from California where the state schools admit by major. So, the major you apply for has a huge impact on your admission chances. Some majors are more popular and therefore have much higher admittance standards .
I can’t figure out if ASU operates this way. If sports business is a popular major, will it reduce his chances of admittance? If so, is he better off applying Undecided? His GPA is 3.53 unweighted, 3.93 weighted. No test scores.
