Is there a way to accurately predict relief pitching in a certain game?

Depends what you mean by 'accurately', and how much trouble you want to go to.

I think a decent crude measure would be to take all the relievers on a given staff, figure out their total K/9, BB/9, and GB%, and plug those into a formula like xFIP.

A slightly better measure would eliminate the relievers who aren't available because of previous usage.

Even better would be running some kind of simulation that takes into account game situations and how the manager uses each of the guys in his bullpen.

For totals, I'd take a weighted average of everyone. For MLs, I'd use all but the closer for innings 7-8, and closer (if available) for 9.

Thanks guys. I stumbled upon the base runs formula and am trying to factor in the relief pitching. I'm trying to find a good site for batter vs. pitching stats. So far i like espn the best for this.

Teampages at statfox include home/away numbers, for bullpen and starters. Can be helpful for totals.
