1. NFL style revenue sharing. Salary cap and salary floor. They floor being 80% of the cap. Teams that exceed the cap or go under the floor are given a loss for every game played from the time they exceeded (or went under) the cap until they returned to compliance. For draft purposes, each loss during that time would be counted as a win.
2. 20 second pitch clock. A pitcher must deliver the ball withing 20 seconds of receiving it from the catcher or a BALL is called for the batter (Umpires' disgression for unusual circumstances). Stepping off the rubber does not reset the clock. If a pitcher calls "time" it would count as a visit from the catcher. Making a pickoff move DOES reset the clock, but the ball has to be thrown to the base. Along with this goes a strictly enforced batter in the box rule.
3. Automated ball and strike calls.
4. All 4 infielders must have both feet on the dirt or on the infield grass at the time of the pitch. Teams can still shift to a short fielder, but it must be with an outfielder, thereby leaving an OF area uncovered. Very big RISK/REWARD move.
5. Points system for determining the standings. A WIN is worth 2 points. A LOSS is zero. No game will go more than 10 innings. If the game is still tied after 10 innings, each team is awarded 1 point.
6. Realign the leagues geographically. With the DH now in both leagues, it just makes sense.
7. Any safe/out - fair/foul - catch/no catch - out of the baseline - interferance can be reviewed (subject to mgr's challenge rules). Review will last no more than 1 minute from the time the ump puts on the head phones. After that, the play stands as called. The ump in New York reviewing the play will be named.
8. Larger first base bag to help avoid injuries.
9. All minor league players must be given free housing.
10. At the end of the season, each team must designate 5 players from their 40-man roster for a compensation pool. Any team losing a FA who signed for more than an AAV of $12M (dollar amount could go up) would be able to select, as compensation, one of the players from the pool of the team who signed the FA. Any player with a multi-year contract must be "protected" and would not be available for the pool. Any player who entered free agency that year CANNOT be put in the pool. The team losing the FA does not have to select a player from the pool. No further compensation would be offered.
