Interesting. I wouldn't have expected high school pitchers WAR to exceed that of the college pitchers. That runs counter to the Moneyball hypothesis

Didn't notice that; it's only 8-years of data, so wonder if a few outliers affect the data. This related piece shows college pitchers outperforming HS pitchers (but I don't know what WAB is). These also ignore later rounds, but I suppose that wouldn't change the mean numbers (should see a steady dropoff).

Separately, is WAR a zero-sum metric? If so, would think pitchers and batters average out over all data.

I think it's a nonzero situation. The defined replacement level is maintained at 0, so that's why you see some negative figures in the table

Sorry, I mean across all pitchers and batters is it zero sum (i.e., Σ pitcher WAR = Σ batter WAR.) If not, that either solves the age-old question (are pitchers or batters more valuable?), or maybe instead shows some bias in the metric.

I have a feeling it would skew a bit towards the batters but I'll have to look at the formulas. Ultimately, they are using two different formulas for pitchers and batters so I would imagine there to be some skew. And, if I recall correctly different sources use different formulas to calculate WAR

I guess WAR is baseball's unified theory; if every instance is a pitching/batting/fielding success or failure, makes me wonder how these balance. In the short term (i.e., no-hitter) there's regularly no balance, so no need for there to be balance in a single season either I suppose.
 

I absolutely loved Mike Piazza! He's my first baseballing hero as a young lad growing up, and I had to pleasure of seeing Piazza and Griffey Jr. both play. Not many non-yanks can say that.

That moment he hit the Homer straight after 9/11, is without doubt the clincher to why he's going in to Cooperstown as a Met!
 
Looking at the voting, if you count Piazza and Bagwell as PED-suspects, the numbers are increasing. I think we'll see something definite when A-Rod is eligible. A-Rod is still several years away, isn't he. Seems these guys will get sorted out sooner rather than later. The cutoff is 75% for election.

Questionable guys:
Jeff Bagwell (surely goes in next year?): 41%, 56%, 59%, 54%, 55%, 71%
Mike Piazza: 57%, 62%, 69%, 83%

The PED guys:
Roger Clemens: 37%, 35%, 37%, 45%
Barry Bonds: 36%, 34%, 36%, 44%
Mark McGwire: 23%, 23%, 21%, 19%, 19%, 16%, 10%, 12%
Rafael Palmeiro:11%, 12%, 12%, 4%
Sammy Sosa: 8%, 7%, 6%, 7%
