What they need to start doing is letting teams post challenges to calls, Have the league review those calls and look at the replays.
And if an Umpire reaches a certain number of bad calls that full replay would reverse in a year he gets the boot!

Mistakes are going to happen thats why pencils have erasers on them, But making Umpires accountable in some way will go a long way to getting rid of those bad calls.

Truth is the technology already exists to determine balls and strikes., The Union would never allow them to use it without going on strike!

An extra umpire is placed off the field as the replay umpire. This umpire is also available to fill-in should an on-field umpire become unable to continue during the game (injury or whatnot). If a manager decides to challenge a call, he leaves the dugout and alerts the crew chief that he is challenging the call (any time a manager leaves the dugout now becomes a challenge). The off-field umpire reviews the play on a 90-second timer and relays the ruling to the crew chief via radio, phone, etc.

Every manager can MISS two challenges a game. If you challenge and are correct, you still have two left. If you miss one, the manager/pitching coach/catcher is NOT allowed to make a mound visit for the rest of the inning (or the following half inning if applicable); the only time a manager/pitching coach/catcher can make a mound visit during this time is for a pitching change. If you miss a total of two challenges in a game, the manager is ejected.

Right now, if a manager argues with an umpire once or twice in a game, it’s likely to result in an ejection anyway, this just makes it the procedure and skips the argument.

I think two things need to happen:

1. Better treatment and training of minor league umps. All umps start out in the minors. With the low pay, lack of respect and treatment they get – for the opportunity to ride buses all over and be on the road quite a bit – they’re not attracting enough talent. They’re getting guys who need a job and are willing to put up with being a minor league ump for a paycheck and maybe for a chance to get to the majors. Attract better ‘talent’ and couple it with better training and we might get a better class of major league umps.

2. Hold the ML umps accountable. Other than being rated every year, is there any accountability for some of these guys that consistently suck at getting calls right?

I agree the games are too long and need to be shorter. I went to a college game (Florida vs LSU), they have a 20 second pitch clock (once the pitcher gets the ball back) and the batter could not leave the batters box.
