I guess I don't shout loud enough, seeing as how not one of my questions has been answered.
How about this to parallel your beautiful example earlier:
Pitcher 1: 3.40 ERA, Pitcher 2: 3.31 ERA, Pitcher 3: 3.46 ERA
Do we know categorically which was better? No way, we don't have enough information. But in bad_luck's world that means:
Pitcher ERA: UTTERLY WORTHLESS!!!!
