Auto-Play - Use Auto-Play to determine winners and losers for as-played and as-scheduled schedules.  You can roll some games and let Auto-Play play the others.  You have the option of using actual results or Log5 method to determine who wins.  Requires MS-EXCEL.  Each season is it's own spreadsheet, but multiple seasons are zipped up for downloading.

Estimating one-game winning percentages

In the 1981 Bill James Baseball Abstract, Bill introduced the log5 method to answer the question, "how often should team A be expected to beat team B?" It took him several pages to describe and justify the method, so we won't take the space to do all of that again here. Instead, we'll just give the formula:

             A - A * B
  WPct = -----------------
         A + B - 2 * A * B

where A is team A's winning percentage and B is team B's winning percentage.

In other words, if you have a .600 team playing a .400 team, this method shows that the better team can be expected to win 69.2% of the games between these two teams:

             .600 - .600 * .400           .360
  WPct = ----------------------------- = ------ = .692
         .600 + .400 - 2 * .600 * .400    .520

Just in case the link is ever down, I have copied the above from www.diamond-mind.com.  The actual link is:

Opening Day Rosters - All the opening day rosters that come courtesy of Gary Leven's "ATMgr for BBW" files (http://groups.yahoo.com/group/ATMgrForBBW).  This is a CSV file that you can import into a spreadsheet or database.  One file contains all 79 seasons available.

Complete Team Rosters - Every player for every team (with fielding positions).  All courtesy from Sean Lahman's database (http://www.baseball1.com).  These are CSV files that you can import into a spreadsheet or database.  All 137 seasons are grouped in 5 text files in one zip file.

Enhanced As-Played Lineup Files - All but 1 season is from Gary's ATMgr files.  1992 is from Retrosheet's game logs (http://www.retrosheet.org).  These are CSV files that you can import into a spreadsheet or database.  Each season is it's own separate CSV file.  Multiple seasons are zipped up.  These are enhanced with 2 new features:  (1) fielding positions are alpha instead of numbers and (2) the starting pitcher's throwing hand is a new field.  Note - The data on some older players is incomplete, so if Sean Lahman's database listed a throwing hand of "blank", I made it a R.  Not perfect, but close enough for jazz.

Transactions -  There are 3 main sources for transactions.  (1) Gary Leven's ATMgr files, (2) Retrosheet's file and (3) an old spreadsheet that I downloaded that I believe Kerry Leibowitz had posted (not for sure the data source).  Individually, I don't think any one source is 100% complete, but I have made all 3 individual sources available, plus I have all 3 sources combined into one zip file, broken out as 3 groups of seasons.  The problem is that it was next to impossible to avoid having duplicate (or even triplicate) entries with the combined source, since all 3 sources use different naming conventions/standards/formats.  These are CSV files that you can import into a spreadsheet or database. 

Most Common Lineups -  For the 80 seasons that have as-played lineups, this text file shows for each team, the most common lineup they used versus a LHP and a RHP for that specific season.  Starting player names only.  No match was done by actual position.  Just the same exact batting order.  Pitchers are excluded from the list, so you will see a blank where the pitcher batted, meaning the other 8 guys determined the most common lineup.  From an historical perspective, looking at all 80 seasons together, the 1984 Boston Red Sox lead the way with the same lineup used versus a RHP at 66 times.  There are only 37 teams over the course of these seasons that used the same lineup versus a RHP more than 30 times.  For most seasons, you typically see the same exact batting order used less than 15 times.  Interesting stuff, although, I don't know how it might be used in a replay project to be honest.  It does show that it is really difficult to nail down one suggested lineup that would match most games played in a given season, just because teams don't typically have just one set lineup.

Suggested Lineups -  For the 80 seasons that have as-played lineups, this text file shows for each team, a starting 8 or 9 batters (non-DH have 8, DH have 9, obviously) and their position.  To determine the batting order, please refer to the next 9 columns after their name.  This will tell you how many times they batted in each slot (leadoff (1st), 2nd, 3rd, etc.).  As a guide, any number that has an (*) next to it means that this is batting slot that this batter was slotted the most.  There will be some ties among the players, so you can decide how to break those ties.  There is a vs. LHP and vs. RHP lineup available for each team.

Unless noted, the downloads should be less than 1MB.  Some are quite large (4 to 7MB).

PDF

versions of Opening Day Rosters, Complete Team Rosters, Suggested Lineups, ATMgr Transactions and Kerry Leibowitz Transactions are available for any season by emailing me with your request.  At some point, they may be made available as a download.  Simply email me at replaybaseball@aol.com and let me know what season(s) you want PDF reports.

***Note - You can also email and ask for PDF versions of the as-played lineups, or if you have MS-EXCEL, I can load the text files (or you can do it yourself, if you are comfortable with importing text files).
