My mop-ups go in and I lose 30-4 and 41-4 in those games. Totally fine with the losses but it doesn’t really seem fair that the teams I was playing against suddenly jump to first in the team rankings on hitting and many of their batters are leading on the awards now. Is there any fix for this aside from not playing mop-ups (which would cost me games given that I like to be somewhat aggressive on IP for my league)?

It also makes Pythagorean a complete joke/useless as a predictor.

No, but in a 162 game season the effect of a couple of games is trivial.

I've seen neglected pitching staffs give up a ton of runs due to to bringing in the same relievers at extremely high fatigue. In that case, I look at it like everyone in that league is feasting on them so not really an unfair skewed stat.

Also noticed I'm a chronic "victim" of underperforming my Pythag, as much as 100 points, but at least by 5-10 games. So I don't put much creedence in it.

And should probably start a thread trying to figure out why.
