Well, it looks like, just as Doug trumped Tim, beating him to the net with his defensive analyses, so Tim has gotten in ahead of me.  The way I was doing it was a little different. Being me, of course, I used equivalent averages to work out how many runs a player was worth, and I calculated both rate of performance (fielding equivalent average) and total performance (fielding equivalent runs). But I compared, not to the average player, but the replacement player, and here's why: because the positional adjustment comes built in to the system. In the AL of 1992, the average SS is 32.9 runs above replacement (RAR); cf, 31.6; 2B, 28.8; 3B, 26.3; LF, 26.0; RF, 24.6; 1B, 16.9. We may quibble with the exact numbers, but the order looks substantially right.  In the equivalent average, I have always set league average to .235. I had decided in hitting that the replacement level batter has an eqa of .180; the name of that replacement level hitter, often as not, is "Billy Ripken". I decided to let the replacement level fielder be the same distance from .235 as .180, but in the opposite direction as I have set it up; that makes for an eqa of .280. (Yes, I can add. Runs are proportional to eqa squared; the difference between 180 squared and 235 squared equals the difference to 279 squared, and I rounded off for simplicity). An all-replacement fielding team would have: Randy Milligan at first (.282), Willie Randolph (.269) at second, Leo Gomez (.279) at third, Walt Weiss (.269) at short, Kevin Bass (.271) in left, HoJo (.257) in center, and Eric Anthony (.277) in right. Ugh.  So, the total number of RAR for a player is the sum of his batting and fielding RAR. I can rate them by total RAR, or RAR per some number of batting outs, like 400. An average player has a total RAR of about 55, 30 batting, 25 fielding.  Total RAR (bat/field)  1. Bonds      152 (124/28)  Ventura    124 (66/58) 2.

One at each position measured! McGriff, despite +85 batting RAR, fifth in league, finishes out of the top 20 due to a -13 in fielding. Last by position:  Galarraga 39, Stillwell -10, Hansen 30, Belliard 30 (Blauser gad a 69, 3rd in league), May 43, Dascenzo 34, Anthony 38.  In the AL, much-maligned Rickey Henderson was worth 120, second only to Frank Thomas' 124; Ventura edges Edgar at third, 116-111; Grebeck rates a potent 102!; Griffey edges Puckett as top CF, 93-90; Listach nudges out Lofton among rookies, 82-80. And Alomar clearly outpoints Baerga, 97-73. Last by position: Segui 10, Sojo 29, Palmer 22, Lewis 31, Polonia 40, Cuyler 26, V. Hayes 39.  All for now.
