Baseball is great, it has been kept pretty consistent over the years, and the one aspect that is being questioned right now, Umpires.  Instant replay is definitely a must for the sport.  I don't know if umpires are worse now than in the past, but they are definitely more scrutinized.  With all the angles we have today, there is no reason to not get the call right.  I know the game runs long, and so I agree with the idea of having a group of umpires watching games in a central location every night.  When a call looks to be controversial, they call the crew in the other city and watch it make the judgment quickly and relay the ruling.  I would also go one step further, they need to get balls and strikes correct more often.  I'm not saying the review applies, but a couple of cameras can video each pitch of a game and be brought into a 3D program to show the actual path of the ball.  This could be used by the umpire to see how well they called the game, and see what calls they may have trouble with to improve in the job they do.  Umpires who consistently call pitches badly could be disciplined.

Why do I bring this up?  Adam Dunn has been the victim of several outside pitches called strikes this year.  He is forced to then swing at those pitches and usually bad things happen (see pinch hit with bases loaded, ball goes 10 feet; last night too.)  Unfortunately the public has the ability to see too much of the game now.  This forces the umpires to have to see everything from every angle so that we can enjoy the game.

Lastly the Umpires need to be held more accountable when throwing guys out of the game.  Edwin has been tossed twice now, and in both cases he should not have been thrown out.  Who ever said Umpires need scouting reports on players was 100% accurate.
