I know this is bout a week behind, but I thought it was an interesting study of how teams hitting and pitching was doing independent of the park they played in and how it related to win/loss.
I don't think that 8 games has changed these stats that much.

Adjusted OPS+ | From Baseball Reference | |||||
1. Compute the runs created for the league with pitchers removed (basic form) RC = (H + BB + HBP)*(TB)/(AB + BB + HBP + SF) | ||||||
2. Adjust this by the park factor RC' = RC*BPF | ||||||
3. Assume that if hits increase in a park, that BB, HBP, TB increase at the some proportion. | ||||||
4. Assume that Outs = AB - H (more or less) do not change at all as outs are finite. | ||||||
5. Compute the number of H, BB, HBP, TB needed to produce RC', involves the quadratic formula. The idea for this came from the Willie Davis player comment in the Bill James New Historical Baseball Abstract. I think some others, including Clay Davenport have done some similar things. | ||||||
6. Using these adjusted values compute what the league average player would have hit lgOBP*, lgSLG* in a park. | ||||||
7. Take OPS+ = 100 * (OBP/lgOBP* + SLG/lgSLG* - 1) | ||||||
8. Note, in my database, I don't store lgSLG, but store lgTB and similarly | ||||||
OPS+ (Link) | From THT | |||||
OPS measured against the league average, and adjusted for ballpark factors. An OPS+ over 100 is better than average, less than 100 is below average. | ||||||
ERA+ (Link) | From THT | |||||
ERA measured against the league average, and adjusted for ballpark factors. An ERA+ over 100 is better than average, less than 100 is below average. |
