The idea is to put VHSL baseball more in line with the NCAA in relation to other HS sports. Basketball plays 22 game (in relation to 27-29 in NCAA). Football plays 10 (in relation to 12 in NCAA). Baseball plays 20 (in relation to 56 in the NCAA). By comparison, that's 1/2 as many games.
Also an effort to get more in line with surrounding states - NC plays 23. WV plays 32. TN plays 30.
