Instruction: Why might the 2023 MLB season break the record for total runs scored in a single regular season?

Response: The 2023 MLB season might break the total runs scored record in a regular season due to three rule changes.. 

1. Base sizes going from 15 inches per side to 18 inches per side. The increase in base size promotes safer stealing conditions for runners allowing them to more easily avoid contact with fielders. Also, the larger base surface area will help runners from "over-sliding" on the base leading to an out.

2. Two disengagements per plate appearance. Pitchers are only allowed two forms of disengagement which will reduce the number of pickoff attempts and mound step offs. In the event of a third disengagement, the pitcher will be charged with a balk leading to a base advancement for any runner on base or a ball given to the batter.

3. Eliminating the shift. When the time a pitch is thrown, all four infielders must be on the infield dirt or grass with two on each side of second base. This new rule will increase batting averages, hits per game, and more doubles.
