Have you ever attened an MLB game?
Yes, but sometimes they feel too long. I hope the league follows through with some of the ideas on how to shorten the games a bit
I like long games. I feel like I'm getting my money's worth. I don't want shorter than three hours.
But the average post-season game is longer than 3 hours. Fans have been complaining about it.
That's true. That's because the managers take the games more seriously. They have lots of pitching changes. I also think thanks to being on TV the commercial breaks are longer.
What about using a pitch clock? Wasn't there talk about imposing a pitch clock if the game time goes longer than 2 hours 55 minutes?
I think the pitch clock is implemented from the very beginning of the game.
It seems like they want to extend the game times. More opportunity for commercials during the tv broadcast means more money for the league. Not to mention the money they're making from fans at the game buying food, etc. 
That is true but the commissioner is vocal about wanting to speed up the game to attract more fans.
The MLB has been trying to make some changes to speed things up (like the 30 seconds to challenge a call and the intentional walk signal) but it doesn't speed up the game by much.
