Not that I know of, though I'd imagine there'd have to be somewhere. I think STATS.com has a database that includes Win Shares, but it's a pay service. I'll look around a bit, see what I can find...

Quote:What the heck is a win share?
For those of you unfamiliar with James' innovative system, a win share is a measure of a player's contribution towards his team's victories. James defined a win share as one-third of a victory, so a team that wins 100 games, for example, will have 300 win shares, no more, no less.
Win shares are parceled out according to a player's contributions measured by dozens of interlocking formulas. To figure win shares for a player, you must:
*Determine the ratio of win shares credited to the offense and defense, which is based on park-adjusted runs scored and allowed;
*Determine the ratio of win shares credited within the defense to pitching and fielding;
*Determine the player's runs created, which is a sum of his offensive contributions;
*Determine the runs created by each player on the same team;
*Determine the outs used by each player;
*Determine claim points used to divide up offensive win shares;
*Determine individual batting win shares for each player on the team;
For pitchers, you then:
*Determine runs saved and the value of wins, losses and saves for each pitcher on the team;
*Determine his claim points used to divide pitching win shares;
*Determine individual pitching win shares for each player on the team;
For position players, you then:
*Determine claim percentages for each team position based on a 100-point scale;
*Determine the points claimed by each position;
*Determine fielding win shares for each team position;
*Determine claim points used to divide fielding win shares for individual players at each position;
For all, you then:
*Add batting, fielding and pitching win shares for each player;
*Round to the nearest integer based on a method that will result in reaching the predetermined total of win shares per team. This is different than the traditional method, which is based on rounding all decimals at 5 or above up and those below down.
Is that enough for you? Fine, now do it for 29 other teams, and you're set. There are numerous calculations each step of the way involving dozens of pieces of data, some more obscure than others. For a more detailed explanation, you can read three archived articles in Leading Off, dated April 30 and May 14, 2002, and Jan. 13, 2003. Or you can (and probably should) go straight to the source -- Win Shares, by James and Henzler -- which in addition to listing win shares, also offers all the formulas needed and explanations and rationale for each.
Zero is the base. A player with zero win shares is said to have not contributed anything to his team's success. Ten win shares represents the contributions of a decent regular player, starting pitcher or closer. Twenty win shares is the measure of an all-star player and Cy Young candidate pitcher (these days) and is considered a very good year. Thirty win shares is an MVP-type year, considered a great year, reached by a handful of players each year. Forty win shares is thought to represent a historic season. Fifty win shares? Well, that's entirely the domain of 19th Century pitchers, Honus Wagner, Babe Ruth, Walter Johnson, Tris Speaker, Mickey Mantle, Ted Williams and Barry Bonds.
The most fascinating aspect of figuring win shares is how logical the system is despite its complexity. While it takes dozens of formulas to reach a final result, much are based on comparing a team's performance to expectations based on league averages. It's a simple concept. For example, one of the categories used to figure a third baseman's fielding claim points are expected assists. This is figured by taking the number of assists made by all third basemen in a league, dividing by total assists, multiplied by team assists and then adjusting based on platoon percentage for each team.
Stated another way, we figure out the percentage of assists made by third basemen, and ask, OK, based on X number of assists by this team, we would expect the team's third basemen to have Y total assists.
Let's use the Cincinnati Reds to illustrate this. In 2002, N.L. third basemen had 5,091 assists. There were 26,931 assists made by every N.L. fielder, so third basemen made 18.9 percent of all assists. The Reds as a whole had 1,773 assists and had way fewer balls in play against left-handed pitchers (which would mean more right-handed batters and therefore more opportunities for players on the left side of the infield), so Reds third basemen would be expected to have 317 assists (actually 317.42). They had 361, 43.58 more than expected, and get credit for that.
While this one little example illustrates the need for spreadsheets to figure win shares, it also should show how delicate the system is. If one calculation, or even one piece of data, no matter how seemingly insignificant, is off, it can throw off your results. And even if your calculations are correct, your results could differ if you use different data. For example, MLB.com lists Bobby Higginson as having 175 at bats and five homers with runners on base, data needed to calculate runs created. ESPN.com lists him with 174 at bats and four homers. The difference throws off the final win shares results for the Tigers.
