In Theory, but not reality
Everyone is swinging for the fences and striking out 180+ times a year, so it won't make much of a difference.
Agreed. Data will show that next year.
So MLB will have do something else to encourage batters to put the ball in the play more. And not trying to hit a home run. Ideally, you would see someone like Rickey Henderson who is capable of hitting a single. Then can steal 2nd and 3rd bases. So he can score easily on a sacrifice fly.
