I don't like taking out your best hitters late in games that are close. I would live with the chance Sano costs you defensively for the chance his bat will matter. I agree that's overmanaging. Caught stealings might or might not be. I might be more inclined to call that bad managing than overmanaging, or possibly just the cost of trying to stay aggressive. IMO the biggest example of overmanaging is seeing Santana have 2 hits one day, then being a lineup fixture, in the two hole, for the next few. What changed about your lineup, or about Santana, based on one day's ABs? That's overmanaging, or perhaps panic.
