And yet another WPA site

Another one to add to your list:

I definitely don’t like the way the baserunning (non-PA) is being handled. I would have either had a “team baserunning” bucket, or split the credit among all baserunners, or just the lead baserunner, etc. But, not hand it out to the batter.

Otherwise, a very fine site.

This is also a very useful resource:

I’m engaged in a lengthy win probability talk, mostly discussing the home field advantage. Frustrating at times, but engaging at others.

First of all, thanks for linking my site here.

Maybe my explanation wasn’t very clear on there, but I am not giving credit to the batter for separate baserunning plays that happen while he’s at the plate. I have just thrown out all baserunning plays altogether.

In other words, I have a “team baserunning bucket” but I just haven’t bothered to look and see what’s in it.

Ah, wonderful then. Well-handled.

You don’t really need to look at it, either. IIRC, for non-PA movements, from 1999-2002, I had Damon leading with +2.7 wins, or about 0.7 wins per season. Not something to worry too much about for the moment.

Good grief, Tango. I just read that Fangraphs thread. You’re too nice!

Revamped the site. WPA values are now based on a WP table derived from run frequency that I got from a one million inning Monte Carlo sim.

There are a few more useful posts in the last 24 hours from dackle and me (I’d suggest skipping over the Okay Fine posts) on the top of win expectancy:
