Interesting Alternative Leagues

1946 Mexican League: Created by 'Rickengeezer'. In 1946, major league baseball was celebrating the return of many of its greatest stars from service in World War II. However, a different type of war was brewing south of the border--a bidding war, led by millionaire Mexican League team owner and league president Jorge Pasquel and his four brothers. Impressive sums were offered to stars like Ted Williams, Johnny Pesky, and Stan Musial, and there were rumors that Babe Ruth had been offered a considerable sum to play a role in the league, perhaps as Commissioner. The big salaries touted by the Pasquels were quite enticing as a result, and in February of 1946 the first big-league player, Danny Gardello of the Giants, signed a Mexican League contract. He helped recruit a number of his Giant teammates, such as Sal Maglie, George Hausmann, and Roy Zimmerman, and the exodus was on. Heavily researched for accuracy, this library contains team logos, estimated transactions, a ballpark image for Mexico City's Foro Sol stadium, and detailed notes describing the history of the 1946 Mexican League.

1966 Japanese Baseball League: Originaly created by James Marshall and Mischa Gellman as a custom Diamond Mind Baseball season, this librar was recently converted to Digital Diamond Baseball. The 1966 season would see the Giants take their second of 9 straight Japanese League titles. Led by the great Sadharu Oh who led the league with 48 homers (129 GP). Oh's teammate and perennial fan favorite Shigeo Nagashima led the Central League with a .344 average and was named league MVP. The Giants Tsuneo Horiuchi went 16-2 with just a 1.39 ERA and was named both rookie of the year and was the co-Sawamura (top pitcher) with the Tigers Minoru Murayama. The Giants faced the Nankai Hawks in a rematch of the previous year's Japan Series. The Hawks won their third Pacific League pennant in a row led by their all world slugging catcher Katsuya Nomura.
1976 Japanese Central League: Created by 'Rickengeezer'. This season was immortalized in Robert Whiting's book, You Gotta Have Wa, that chronicled the challenges of mixing the Japanese and American approaches to baseball. As quoted in that book, new '76 Yomiuiri Giant starter and former California Angel Clyde Wright grumbled "I don't know what it is they play here. All I know is, it ain't baseball." A lengthy excerpt from the book can be found in a 1979 Sports Illustrated article. This library includes a complete schedule, team logos, and ballpark images.

Minor League Libraries

1981 International League (V6) (V5): Created by George Curcio. The 1981 International League marked the season during which Cal Ripken played for the Rochester Red Wings. The schedule is the actual schedule used by the 1981 IL. It was acquired from the International League office - a special thanks to current IL President Randy Mobley for his assistance. Transactions are a combination of Major-League transactions that were edited to include only those affecting 1981 IL teams, and actual 1981 minor-league transactions that were culled from the achived 1981 issues of The Sporting News.
2016 Pacific Coast League: Created by George Curcio. This library contains opening day rosters, real-life transactions, and a custom play-by-play file that adds some PCL flavor to the play-by-play! The library creator (George) is using this PCL library (and some of his other DDBB libraries) to highlight prospects that he may have been unaware, and use the information on Draft Day next year for the Fantasy league he competes in.
2016 Southern League: Created by George Curcio. This library contains opening day rosters, real-life transactions, and a custom play-by-play file that sprinkles in a few "Southern League" references during the game! The library creator (George) became interested in the Southern League while watching the Jacksonville Suns on MILB.tv. His goal was to see if he could do any better as manager of the Suns than the team performed in real-life.
1970 International League: Created by George Curcio. The Sporting News provided much of the information for this library. Issues for each week of the 1970 International League baseball season were reviewed, with the actual schedule and transactions recorded for use. The Opening Day rosters for each team are set as reported by The Sporting News on May 9, 1970. Transactions are a combination of the Major League "callups" and "send downs," which were edited from the "Baseball Goodies" transactions file, and minor-league deals as reported each week by The Sporting News. Many future "major leaguers" are included among the 1970 International League library - some became major stars, some "flamed out" in the majors after having stellar minor-league seasons.
1925 Pacific Coast League: Created by Edward Meek, this library was heavily researched for accuracy.

Creative Compilations

80s Franchise Players (V10): This custom library was created using the most impactful three-year span (in some cases two-years) of franchises players neutralized to 1989 in a neutral park and dividing by three. Each team has 32 players (20 baters, 12 pitchers). The players were picked based on playing time in the decade for the team spread among the different positions including starting pitchers vs relief pitchers. The mid-year of the three-year span was any season between 1980 to 1989, which is the age of the player in the library if you want to look it up. Fielding ratings were scrapped from the base libraries within the game, on a prorated basis, if a player averaged at least 15 games at the position. The run rating came from a modified version of Bill James speed rating.
Best of the 1910s: Created by Joe Caracciolo. This library consists of the best teams in MLB during the 1910 decade. Each of 16 franchises is represented in this library.

Baseball's Best Teams 1960-1980: Created by George Curcio. This library features the Top Ten teams from the 1960-1980 era, and is based on the ELO rankings. Left/Right splits for both batters and pitchers are included. Players were allowed to play for only one team (thus, as an example, Roger Maris played for the 1961 Yankees and NOT the 1968 Cardinals; another example is Tim McCarver playing in this library for the 1968 Cardinals but not the 1977 Phillies). There were some teams that had multiple high-rated seasons within several years of one another (the Orioles, Reds and Pirates in the late 1960s/1970s often repeated). In that case, the next organization in the ratings that would not "conflict" in terms of players was selected. The teams included in this library are the 1970 Baltimore Orioles, 1976 Cincinnati Reds, 1961 New York Yankees, 1974 Los Angeles Dodgers, 1978 New York Yankees, 1968 Detroit Tigers, 1979 Pittsburgh Pirates,1977 Philadelphia Phillies, 1978 Boston Red Sox, and the 1968 St. Louis Cardinals.
1960 Franchise Decade Teams: Created by Jeffrey Kik. This library is comprised of 20 teams from both leagues, each containing the best players during the decade (using the player's best season). For defensive statistics, the average was taken across all seasons played by each player. Library includes full rosters, DH lineups (L/R), rotation/bullpen profile settings, and left/right splits.
Bring Your Best - 2017: Created by Jeffrey Kik. This library contains over 4000 players spanning 110 years of MLB! The stats for each player are taken from the player's best season.

Top Teams of the 1930s Decade: Created by George Stimac. This library contains 16 of the top teams from the 1930's decade, an era of power and offense! Included in the library are accurate and complete rosters for 16 teams as well as team profiles, custom player ratings, and detailed notes for each team in the library.
1965-1973 Franchise Library: Created by George Curcio. This library is based on players who actually played for a franchise between 1965 and 1973. For a player to be included in this library, he must have played more than 100 games in one season (position players), or pitched in more than 25 games in one season (starting and relieving combined) for one franchise. Each player appears only once in the library. In cases where a player was with more than one franchise during the timeframe of 1965 to 1973, he was assigned to ONLY one franchise for which he actually played. The determination of teams was based on a combination of some of the following: actual games played for each franchise, best season totals for one season, and personal whim and remembrance. The season in which each player posted the highest "Wins Above Replacement" was the year chosen for their stats in this library.
Player Libraries for the Hardball Retrospective Book (1901-1910) and (1911-1920): In Derek Bain's book Hardball Retrospective: Evaluating Scouting and Development Outcomes for the Modern-Era , Derek has placed every ballplayer in the modern era (from 1901-present) on their original teams, and using a variety of advanced statistics and methods, he generated revised standings for each season based entirely on the performance of each team’s “original” players. The book also contains a discussion of every team’s “original” players and seasons at length, along with organizational performance with respect to the Amateur Draft (or First-Year Player Draft), amateur free agent signings, and other methods of player acquisition. Fortunately for the Digital Diamond Baseball community, Derek is also building Digital Diamond Baseball libraries for each season in his book, and is making these available for download for free! The first 20 seasons (1901-1920) are available now, and more libraries will be added over time. Thanks Derek!
The Universal Baseball Association: Created by 'Rickengeezer', this library represents a recreation of the Universal Baseball Association, the centerpiece of Robert Coover's 1968 book "The Universal Baseball Association, Inc.: J. Henry Waugh, Prop.". Often hailed as one of the best baseball books of all time, it tells the story of J. Henry Waugh, an accountant who immerses himself in his fantasy baseball league every night after work. This library is patterned on the fateful 56th season of the UBA, but precise statistical information on the players in the league is largely absent in the book. Thus, rather than a true simulation of Coover's universe, this library is an approximation--but one that uses the names, positions, and descriptions of the ballplayers to guide the selection of statistics for ballplayers like Maggie Everts, the bowlegged old catcher, or star centerfielder Witness York, who led the league in slugging percentage. Virtually every player mentioned in Coover's volume is included in this league, although it should be noted that many of these players were "historical" figures in Henry's fantasy--nonetheless, all are included in this UBA season. In order to round out the full league, other players are also included, but an effort was made to maintain consistency with the naming conventions and player characteristics found in Henry's project. The eight UBA teams play an 84-game schedule, as they did for Henry. But, perhaps the fate of the players will be different in different hands.
Movie All-Stars Library: Created by 'Rickengeezer'. Baseball has provided the subject matter for many feature films, some great and some not-so-great.

Also included are player pictures, detailed documentation, and one home ballpark for the team (The Field of Dreams).
2017 NCAA Library: Created by 'FBJones', this epic library contains 220 NCAA teams populated with statitics from the 2017 season. The library contains a schedule, team profiles, and detailed notes about how the libray was created. A must have if you are a college baseball fan!

Also includes day and night ballpark images and team logos.
Career All Stars Library (Updated 2015 Version!): Created by Bruce 'Mac' MacLeod, this very popular library contains major league players with at least 5 active seasons from 1901 through 2015. Career totals were calculated by Mac for all of the players in the library. The library contains enough players to populate 36 teams. This is a great library for drafting!
The World Baseball Association: Created by Bruce 'Mac' MacLeod, this library contains 24 teams arranged in 2 leagues, 2 divisions per league, and 6 teams per division. The library contains a large Free Agent pool for use as replacement players as desired by the user. 'Mac' suggests the following strategy: Play three years with the existing rosters. At that point, determine the total team W-L records. The teams with the worst records in each division will be allowed to exchange 2 players with the Free Agent pool and the next worst teams will be allowed to exchange 1 player. The exchange must be like for like (i.e. a starting level player for a starting level player; a backup level player for a backup level player) and the same position (i.e. Catcher - Catcher; RP - RP). After future season replays only the worst team will get to exchange 1 player.
