Throw the damn pitch already; it shouldn't take two minutes to toss a ball 60'6".
It shouldn't, and the MLB is experimenting with fining pitchers if they take excessive amounts out time. Batters have to keep their feet in the box, no wandering away anymore and rechecking their gloves, cleats, etc.
Here are experiments they've tried:
1) Revising rule 8.04, requiring the pitcher to deliver the ball to the batter within 12 seconds after he recieves the ball with the bases unoccupied. A violation is an automatic "ball" from the umpire. If the batter steps out of the box during the 20-second period (they had a clock on the field), the pitcher may deliver the pitch and the umpire may call a strike, unless the batter was first granted time by the umpire.
2) Batter's Box Rule: batter must keep at least one foot in the batter's box unless a predefined exception occurs.
3) No-pitch intentional walks. You want to intentionally walk someone? Just say you walk him and it's done. If a pitcher has control problems though, he can screw up an intentional walk, which I've seen in person. This would sadly eliminate that situation too.
4) 2:30 inning break clock.
5) 2:30 pitching change break clock.
6) Three "time out" limit.
#4 and #5 are opposed by TV networks because it cuts down on the number of commercials they run. Major league players had difficulty adjusting to the rule changes, so the rules are going to be rolled out in the lower leagues first: first Double-A baseball, then Triple-A, then the MLB. Unfortunately it's not yet a given that all these rules will enter the MLB. However, in having them enforced in the minor leagues first, major leaguers will get used to them.
