Failure signs

• Your team gives up leads of 4-0 and 5-2
• With the game tied in the 9th, an error turns a routine ground out to a runner on second base. Now on 3rd with one out, you intentionally walk two players to load the bases and face someone who has a lifetime 1.000 average in bases loaded situations.
• As expected you lose the game.

I have absolutely no idea who could be the man to mastermind this failure. A failure so knowing and obvious as the later innings arrived, that a fan of another team (a team this man used to manage) predicted this fade long before. Who could it be?
