I looked at the Champ League and I think I know the game you are talking about. I think the opposing managers’ strategy is that you were crushing his lefties, so why not take the chance on a righty reliever starting.

Because of the 4 run/4 inning rule, he probably didn't want to take the chance of starting a lefty.

Anyway, I would be pissed to that I lost, but it is still within the rules. The opposing manager rolled the dice and won.
