For some reason, I don't consider speeding up the game up to gamesmanship. By speeding it up, you're making it more like a real game - that is, closer to the 7-inning game it was intended to be. Also you're sacrificing a batter to do it. That's unlike intentionally and artificially slowing the game. Slowing the game makes the clock a factor (which is not how the game was intended to be played), and it also shafts the other team. Speeding the game doesn't really shaft anybody.
You need to look at this differently. It IS how many travel ball tournaments are intended to be played. The clock is just another factor for consideration. Just like batting order, player positions, etc.....
Those who are so opposed to the clock, why do you enter tournaments that use a clock? It's part of the travel "tournament" structure to get games in. Put yourself in the shoes of a tournament director. You've got so many games to get in and for the most part couldn't care less who wins or loses. Just get the games completed. That's the goal. They churn out games like General Motors churns out junk.
How often does rain cause the TD to short games? Often in my experience. Sometimes just pool games get shortened, sometimes like this past weekend the entire tournament takes a hit. All games going to 60 minutes finish the inning. The clock really becomes a factor in these games.
Like it or not the clock is here to stay for the majority of travel tournaments. Manage it as such. You win some you lose some via the clock, TD's don't care. You score more runs at the end of an inning during a timed game, you win and move on. If not, you're playing again next weekend anyway.
Anyone so opposed to this either needs to make sure their team stays ahead from inning 1 and beyond or simply don't get into a timed tournament.
