win exp, july 27th.

look at the horrible overlays!
the 'zzz' refers to the boring states of the graph, not me during that period of time...
anyhow.. PoG: Kendall, mostly because scoots had a 9th inning ab (see the big decrease between dj+jp and kendall... that was scoots) and 3 beforehand that were unimpressive to wpa.
prior to bott9: 9.4%
Kielty hit: +8.8% - 18.2%
DJ hit: +15.5% - 33.7%
Payton hit: +18.5% - 52.2%
Scutaro botched bunt: -18.5% - 33.7%
Kendall hit: +50.5% - 84.2%
prior to bott10: 64.2%
Hatty out 4-3: -5.9% - 58.3%
Kielty out 4-3: -4.8% - 53.5%
Ellis single: +2.8% - 56.4%
Payton double: +6.9% - 63.2%
Scutaro walk-off: +36.8% - a W and happy A's fans
The most important hits are all in there.
I'll leave it at that.
Great game. Let's do it in a simpler way next time.
- below is an analysis of baseballgraphs v walkoffbalk -
By the way, I'm still using the "computer says" part of this to do the graph; I've found that "history says" and "computer says" really aren't off that much when the computer is on default RPG (4.7 per side)- however, the computer also takes run environment into effect. I personally have no idea what effect it has, but I think it works (eg: in Coors or TX, a 6 run deficit isn't as much as it was in preremodeled Comerica)...
Also, history says gives some absurd versions of zero due to small sample size.
Take this series of numbers:
bott9 - 6-0 visitors:
a) begin: 1/3062
b) runner on first: 1/768
c) runner on first and second: 0/204
d) runners on first and third, run in: 0/24
... basically, that doesn't make much sense.
in the same situations, computer says:
a) .996
b) .994
c) .983
d) .960
... that makes a little more sense.
Basically, that and run environment are the reasons I don't use walkoffbalk. However, I am getting fed up with .500 at the end of any inning at a tie.. that should favour the home team.

One Suggestion
Explain WPA for me . . .
by Josh @ Athletics Nation on Jul 27, 2005 7:29 PM PDT reply actions
WPA is...
Defence is not included because I do not watch games. If I did watch games, I'd eyeball range factor, but I don't, so I can't.
I only count defence in three situations:
- stolen bases/caught stealing (usually 50%C-50%P, or about so)
- rundowns.
- errors. (usually 90-100% to fielder)
thanks . . . I like this.
The WPA is very dependant on the situation of the ball game (e.g., Kielty's HR while alone accounting for 1/5 of the total winning score only seems to jump the win exp around 10%, while Scoot's GW RBI drives it up around 50%). I argue that independent of the game situation, Kielty's HR (both R and RBI) was more important (on an individual level) to the win than Scoot's simple RBI.
That being said, WPA could maybe be averaged in the aggregate (after the season is over) and a player's average WPA can shed some interesting light on how they do with situational hitting.
A different way to measure the elusive "clutch" factor possibly?
Are you going to average the A's WPA at the end?
Good shit.

nope.
Guys like Jeff at Lookout Landing and (who?) at McCovey's Chronicles do do it everyday, and they'll probably just add it up at the end of the year.
I do it when I feel like doing it... basically a game which could yield a "cool" winexp graph.
I didn't get to watch this game either
the alert toss to nail [someone] at home.
That was Crosby's doing.
tricky to score
I meant
graphs graphs!
Foolshgame22 breaks ankle, -10%
Nico foul ball maims passing goose, +5%
etc...
ps. For some reason I just like the historical data better. Its biggest problem is that run scoring is up so it's easier now to overcome big leads. Nonetheless, there's something comforting about knowing it's based on data not a simplistic model (especially one that's home field neutral).
i like the historical data too..
In places like Texas and Colorado, the run environment is too high for the historical data to take, so I'll use the model.
That being said, if anyone takes the walkoffbalk thing and puts it into the spreadsheet like the model, I'll startusing walkoffbalk for most games (read: pretty much everything except Texas)
i like it
