Obvious Basic Managerial Strategy (that no one uses)

Managers get fired all the time. They get fired for using the wrong batting order (Buddy Bell), overworking their pitchers (Baker, among many others), not changing their lineups enough (Torre? I don't know, there must have been a reason he was fired!), over using their bullpens, misusing their bullpens.

Often managers get fired for decisions that were only even ARGUABLY wrong!

Here is my my proposed, groundbreaking, dare I say brilliant, managerial tactic. You guys (and one, known, gal) tell me if there is a reason NOT to do this everytime.

When you are a road team in the National League, you bat first. Why not "start" someone other than your SP (i.e., yesterday's starting pitcher) batting 9th? Then, if the pitcher's spot gets up in the 1st inning, you will have the option of pinch-hitting for your pitcher in the 1st inning without giving up your pitcher! It's like a 1st inning DH!

Think about this. Your team takes a 3 run lead, makes two outs, then loads the bases. It now has a 3 run lead in the first inning (not even close to an insurmountable lead), the bases loaded, and two outs!

Bases loaded two out is the IDEAL time for a pinch hitter. Indeed, your BEST pinch hitter.

The only reason you wouldn't pinch hit is because it's the first inning and you don't want to take out your starter.

BUT, if you "start" someone other than your starter, that is taken out of the equation. You can pinch hit Lenny Harris (or whoever) and maybe blow the game open right there.

If the situation doesn't come up, you just bring in your intended starting pitcher, as planned.

Why not? Why not do this all the time? What is the downside?

I know the scenario above is rare, but some version of it happens to each team a couple of times a season. Why not take every advantage you can?
