I didn't see the first-pitch by Ann G (wife of Jim G), but I heard about it from Jim and loved the story.
Recall that she was honoured with the first-pitch at a sellout Cards-Cubs game, as part of recognition for being Teacher of the Year in her district.
As it turned out, she completely hammed it up. After being announced, she used exaggerated motions to place the ball in her glove, and leaned into read the sign from the catcher. With a big shake of her head, she called off the first sign, which was echoed by the stadium announcer and delighted the crowd. She nodded to the second signal, and slinged one homeward.
Apparently the place just loved it. We are trying to locate some video (there is a clip but it is in an internal section of the school district's website).
