Odd Event and an Offbeat Nerdy Question

In an 80s mystery league, Ken Schrom on my team pitched a complete game, did not issue any walks, and had no strikeouts. It got me to wondering what his K/BB ratio would be. This would almost be like a Calculus limit question. If he issues the walk first, then it would be 0, but if he gets the strike out first, then it would be infinity. Thoughts??
