There is plenty of time for your 2022! All these commits are "verbal" and much could change over the next 3-4 years. I wouldn't pay much attention to who commits when and where. Your son should concentrate on improving his strength and baseball skills this fall and spring. The summer between sophomore and Junior years is the opportunity to attend showcases and participate in the various travel tournaments.
After the summer you should have a good idea of what type of programs (D1, D2, D3, NAIA etc..) are showing interest and you can then "plan" from there.
Good Luck!
