If you've ever been on a tour of Petco Park, you may have walked right past one of it's great secrets. Attached to the wall is what appears to be a simple flat gray electrical box. Only if you look closely would you see etched on a black metal label the Major League Baseball logo and the following words:
Property of the Office of the Commissioner of Baseball
For use by authorized Major League Baseball personnel only
What secrets are protected behind this box with two locks? Well if you were clever enough to read the title of this post, then you already know it's the Instant Replay Console at Petco Park.
In 2007, the General Managers voted 25-5 to approve Instant Replay. In 2008, Bud Selig made Instant Replay available to review boundary home run calls. Only the Umpire crew chief and at least one other member of his crew are allowed to open the box to review a play on the field.
I presume that each umpire has a key on a neck chain. The chief and his crew member place the keys into the dual locks and turn them at the same time in order to open it. It's just like you'd see a submariner captain and his first mate do before a nuclear missile launch.
Once the door of the box is opened they'll see a 2008 model Sharp Aquos LCD television, the official sponsor of MLB. A phone is also installed in the box and they'll use it to call a technician in the MLB.com's New York office to have the play cued up for them.
Each Major League ballpark has a similar box. This particular box at Petco Park has only been used twice in the line of duty. Both happened in a 10 day time period in 2010.
The first occurred on 8/25/10 vs. Arizona:
Drew drove a 3-2 fastball from Wade LeBlanc to right field, and the ball caromed off the fifth row of seats onto the field. First-base umpire Ted Barrett originally signaled the ball was in play before the hit was reviewed and ruled a home run.
The second occurred on 9/4/2010 against Colorado when Adrian Gonzalez asked the umpires to review a double that he thought was a home run. Here's video of the double that was not overturned.
Now you know the secret of the Instant Replay Console box. Keep it hidden in your heart behind two locks.
