I think we need to reduce the BS/L even more than that.
The problem is the negative value of the BS and the loss.
There's nothing "positive" that a pitcher can do to make up for that, like getting a W and a save in the same game.
Now that I'm keeping track of the games with a BS and a L, we'll be able to see just how much impact they actually do have.
As I said somewhere before, when it does happen I think it's mostly a matter of luck, since the top closers all have a conversion rate of about 85% or better.
