As I wrote this last night:

Fox just pointed out that there is no action in the Cubs bullpen. I think that's a mistake this late in the game. You have to be ready for anything.

Here's a post from last year's World Series. Here's another. And here's one that summaries the whole thing and compares Baker's moves to the 1965 World Series.

Finally, to show Dusty didn't learn his lesson, this from August 24th of this year:

As I watched the Cubs-Diamondbacks game, it struck me that Dusty Baker did not do a good job of preparing for things going wrong. He brought in Kyle Farnsworth, but Farnsworth was wild. After he had gotten in trouble, Dusty started the bullpen working. But why didn't he have someone up right away? The DBacks are a good offensive team at home; in this day and age, when few teams can trust their relievers, Dusty needs to have someone ready when his pitcher is in trouble. He wasn't prepared today, but he was lucky it didn't cost him.
