This is a step in the right direction. I'm pro pitch clock, but more importantly I think they just need to go back to keeping the batters in the box. When they did that a few years ago with fines the game times dropped. Then that initiative went away for whatever reason and game times went back up. If you do this then the game flows quicker, and without the mound visits we avoid random stoppages of play. My last request would be only 2 warm up pitches for relievers once they enter the game.
I went to the Rockets game last night, and even though I'd much rather go to an Astros game - at the Rockets game I was not constantly wondering how late I would be there. Instead it was "wow the game is already in the 4th quarter?" Baseball probably will never be like that, but I think the flow needs to improve.
