I think it would. To make the transition a little easier, one could start with the rule that every reliever either has to start an inning, finish an inning, or make 30 pitches. While this wouldn't be as ideal as my first suggestion, it would at least eliminate the worst possible time wasting scenario where a reliever enters the game mid-inning (wasting 5+ minutes), gets one out, and then gets relieved for AGAIN (wasting another 5+minutes). Most of the time, not even beer is sold during this interlude, since it usually happens after last call. The worst time waster in baseball is during every pitch, of every at bat, of every game. Pitch, batter steps out, undoes his batting gloves, takes 17 practice swings, looks around, adjust jersey, more practice swings, adjust cup, step in, tap plate, call time, redo, etc, etc, etc, etc, etc, etc, etc, etc, etc, etc, etc, etc, etc, etc, etc, etc, etc, etc, etc. It used to be that there were select players that took part in this ritual, now EVERYONE does this. EVERYONE. This wastes WAY more time than the 2-3-4 times per game that we might see a mid-inning pitching change. Do you need to unzip and re-tighten your batting gloves 5 times per at-bat when you didn't swing? I'd wager that you probably don't. Brandon Belt had a 21 pitch at bat back in April and that took THIRTEEN MINUTES. That's absolutely ridiculous. I'm not a huge Brent Suter fan but I like watching the guy work. He gets the ball and he pitches.
