My only complaint about the length of baseball games is the 7:05pm start time. I love going to moderately attended games with a bit of a lazy feel but I’m not going to go to a worknight game when there’s a fair chance that I’ll not be home until after 11.
Returning to an era where I could be pretty confident the game would be over by 9:30 would be a great boon in that regard.

In poking around I see that the average Japanese professional baseball game is about 20 minutes longer than a US game. I don’t know anything about them to know why that might be.

Just to set an ideal bar for game length without changing the way the game is actually played, last year the Yankees saw an average of 155 pitches/game. The Red Sox saw 154 for a total of 309 pitches per game.
So just in 12 seconds/pitch that is a minimum of 61 minutes, 48 seconds of time.
To the 61:48 we add:
42:30 for the 17 side changes taking 2:30 each.
Lets say that every time the ball is hit or someone goes from home to first (or farther) it takes and average of 15 seconds to get the ball back to the pitcher (made up number that strikes me as maybe a bit low). The Yankees and Red Sox averaged a combined 92 hits, walks, hit by pitcher, sacrifices, ground balls, and fly falls per game. So that’s another 23 minutes.
Now up to 127 minutes, 18 seconds.
Maybe a 15 second gap between the end of one plate appearance and the start of the next. The Yankees/Red Sox combined to average 79 plate appearances per game. Subtract the 18 that ended a side leaving 61 and another 15:15.
142:18 now.
And now the pitching changes. In 2009 the Yankees has 623 games played by pitchers, the Red Sox 625. Remove the 162 starting pitchers from both and that works out to 5.6 pitching changes per game. If we’re stingy and say a pitching change should take no more than 3 minutes (dammit, they should sprint from the bullpen) then that is another 16:48 per game.
So 159:06 or 2 hours, 39 minutes, 6 seconds (assuming my math is wrong as it likely isn’t when doing this during a conference call) is about the shortest we can expect a Yankees/Red Sox game to be (pick off attempts, foul balls, stolen bases, and legitimate timeouts aren’t included in here) without putting some kind of restriction on strategy used by the coaches.
Kind of surprised that maybe only 30 minutes or so of excisable fluff in a game.
ETA: I know there’s an error in there somewhere since I have more plate appearance outcomes (92) listed than plate appearances (79) but I’m not going to be bothered enough to find it and fix it.
