During the 2017 season at the Coliseum, a sign was installed in the centerfield wall just to the right of the 400 foot marker depicting the worlds "Holy Toledo" in a script font. The sign's lighting effects are controlled by a large button in the home radio booth. When Ken Korach deems a great Oakland A's play Bill King worthy, he presses the button, and the sign flashes. It can also be used for other occasions during the course of the game, as controlled by the A's production crew.
