The rule should be two fielders on either side of second base, three fielders on the outfield grass max. The penalty for breaking it is automatic advancement of all base runners for the first offense and ejection of the player for the second.
I wouldn’t mind a pitch/batting clock. Of course, some of the stepping out and calling time is gamesmanship that is used to mess with pitchers or batters. So I’m not sure what the exact solution is there.
I also love the 7 inning double-headers and hope they become a staple in the future.
Unless there is another COVID season, doubleheaders will go back to being a rare occurrence. The 2021 schedule, which is already out, has none of them. So, whether they are seven or nine innings won’t matter much in normal times.
Curtiss took awhile in his stretch position a few times last night. One rule you might do is that if a pitcher holds the stretch for more than say 4 seconds, it is an automatic ball. As soon as the pitcher gets set, the ump would start a 4-count and if he hits four and the pitcher is still in the stretch, call a ball.
Speaking of John Curtiss, the Cardinals used to have a lefty named John Curtis – got him from the Red Sox. I saw him pitch a dandy game in 1975 at San Diego as part of a double-header sweep out there that summer. My girl friend at the time, later my wife, now my ex-wife, and I drove down from LA and spent the day in SD kicking around and taking in the double-header.
