Baseball is timeless. 27 outs with the lead has been the standard for over 150 years and now there has been talk about a clock. Replay has been a disaster and a clock would be the end.
You want to speed up the game? End walk-up music. That makes the process of walking to the batter’s box longer. 30 seconds of walk-up music times a minimum of 54 batters (27 outs per side) makes almost half an hour.
Limiting mound visits is fine with me. Some of teh other changes are fine. I do NOT like the no-pitch intentional walk (and it certainly seemed to surprise Yadier Molina last night.)
Technically, there has “always” been a pitch clock (at least, for as long as I can remember.) The truth of the matter, though, is that there is no penalty. if they called a ball when the pitcher exceeds the allotted time (or a balk if there are men on base), that would be MUCH more effective than a clock.
