The only way to get in more games is to play doubleheaders on the weekends.
Then the fear is one Saturday with rain and you have to make up two games.
7 weeks with 4 games gives you a 28 game season, but that's a lot of extra money and a lot of strain on a pitching staff for any one high school.
Regular season should be 20 games.
I personally think the field should be smaller, 12 teams.
6 auto bids and 6 at large.
Top 4 with current point system get a bye.
Seeds 5-12 play a one game play in.
5-12, 6-11, 7-10, 8v9.
This year for example all the one game play ins would be May 20th. (Rain May 21).
Then you reseed the remaining in a double elimination 8 team bracket starting May 23rd.
Could have it done by May 30 depending on how many days in a row you want to play.
Most (not all) feel that more teams would make the tournament better, I disagree I think more games with quality teams would make the tournament better.
