So I'm reading Foul Ball, and wouldn't you know...

Fifth inning and we're down 3-2. Bases loaded, nobody out. I'm warmed up. I get the signal. I climb into the golfcart that will take me to the mound. Yankee Stadium, and my heart is thumping under my warm-up jacket. It feels like a World Series. As the cart rolls along the clay track in left field I hear the fans saying, "Hey, that looks like Bouton." "Yeah, it is Bouton." My public.

Lovely little cameo, I think.
