Adjusted OPS+

This value is calculated differently from the Total Baseball PRO+ statistic. I chose OPS+ to make this difference more clear. PRO+ as best I can tell is

OPS+ = PRO+ = 100 * ( OBP/lgOBP + SLG/lgSLG - 1)/BPF

Where lgOBP and lgSLG are the slugging and on-base percentage of a league-average player, and BPF is the batting park factor. This takes into account the difference in runs scored in a team's home and road games, so it doesn't depend on how good an offense or defense a team has.

My method is slightly more complicated, but I think it is more correct. The BPF is set up for runs and the way it is implemented in PRO+ applies it to something other than runs.

    My method
  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 for lgOBP and lg(Times on Base), this makes calculation of career OPS+ much easier.

Career "High"

Below that is the career high for the player in each category. It is not their best season, but the best (highest/sometimes lowest) from all the categories. You can quickly see what Barry Bonds's career highs in strikeouts were along with walks, home runs, etc. I required the qualifying number of plate appearances in a season to be considered for the career best BA, SLG and OBP entries to be 1.55/team game. If I didn't do this you would end up with some players having a 1 hit in 2 at bats cup of coffee as their career best batting average.

162 Game Average

This is an attempt to condense each batter's career into a single season's worth of stats. With batters this is easy. Just take their career games played and divide by 162 and then divide their career totals by that factor.
