2017 ZiPS Projection Database Update Tool

Starting in 2015, Diamond Mind Baseball has produced two sets of player projections, one at the start of the season and a mid-season edition released in late summer. With an additional half season (or more) of play to analyze, many players have revised ratings, projections, and event tables. There are also some new players who did not get rated in the first edition but who have since seen time on their parent club. Projections for these new players are included in the updated mid-season edition.

We realize that many of you have been using the initial projections to play along with the real-life season or have set up draft leagues. Some of you have asked for a way to continue to play out your season with the newly updated player event tables and ratings AND keep your existing league structure, team rosters, and simulated game results. The update tool will enable you to do that.

Before you use the update tool, we STRONGLY encourage you to make a backup of your existing projections database. This is the database you've been playing using the player projections from the start of the season. With your projection season as the active database, go to the File menu and choose Backup. Enter a name for your database backup file and click on the Save button. This will make a backup of your database as it stands at that moment.

In the unlikely event that something were to go wrong while running the update tool, you'll be able to start DMB back up, go to the File menu, choose the Restore option, select the backup file you just created, and click on Open. After you confirm that you want to replace the database with the backup, you'll be back to exactly where you were in your season when you made the backup.

When you download the projections update tool, it is saved to the Downloads folder or to the folder that you specify. Before you run the update tool, you'll need to make sure it is saved in the folder into which you installed Diamond Mind Baseball -- that's C:\dmb11 if you accepted the default location, something else if you chose to install the game elsewhere. It doesn't matter whether you download the file directly into the dmb11 folder or download it somewhere else first and then move or copy it to the dmb11 folder.

Make sure that Diamond Mind Baseball is shut down before using the update tool!

To use the update tool properly, in step two (shown in the image below) you need to select the season database folder for your league that you've been playing using the first release of the ZiPS Projections database (for example proj2017a_v11).

Next, at step three (shown in the image below), select the season database folder where you installed the new, mid-season update database (for example proj2017b_v11). (The updated projections database must be installed in DMB for the update tool to find it.)

After you have selected the two projection database folders, click on the 'Copy new player ratings' button. The update tool will then copy all new ratings, projections, and event tables from the new player project season folder to the players in the the first release of the player projections. In addition, all new players in the mid-season release will get added to the initial release of the player projections as free agents. No statistics or game results will be lost. You will then be able to continue your league exactly where it was left off.

After the update tool reports that the operation was successful, you can continue to update another first release, ZiPS Projections database by selecting a different folder or if you're done, click on the 'Finished' button.

1944 Deluxe Past Season with transaction and lineups available now!

1944: Show Me an Exciting Season

by Steve Ehresman

In January of 1942, President Franklin Delano Roosevelt sent a “Green Light Letter” to Baseball Commissioner Kenesaw Mountain Landis, expressing his desire “to keep baseball going.” With that, Our National Pastime continued for the duration of the War, despite the absence of many star players. Gone were Joe DiMaggio, Bob Feller, Hank Greenberg, and Ted Williams, to name but a few of the luminaries who defended our nation. In their place were players, ineligible for military service, who carried on baseball’s legacy. In 1944, the third season of baseball during the War, Missouri found itself home to not one, but two pennant-winners--the perennially powerful St. Louis Cardinals and the improbably successful St. Louis Browns--producing a “Show Me State” World Series that would never be duplicated.

Wartime baseball has assumed a niche in sports history, an extraordinary period in which those who were unable to serve abroad were given an opportunity to serve at home. Suddenly, the sports pages were filled with new names. Among position players, batting average leaders Lou Boudreau (.327) and Dixie Walker (.357), home run champs Nick Etten (22) and Bill Nicholson (33), runs batted in winners Vern Stephens (109) and Bill Nicholson (122) all emerged to set the pace in offense. On the mound, the one-two punch of Detroit Tigers Hal Newhouser (29 Wins and 187 Ks) and Dizzy Trout (2.12 ERA) paced the Junior Circuit, while Bucky Walters (23 Wins), Ed Heusser (2.38 ERA), and Bill Voiselle (141 Ks) led the way in the Senior Circuit.

The story of the year, however, was the St. Louis Browns, capturing their one and only pennant before their move to Baltimore. With shortstop Vern Stephens leading the way, the Browns edged out the Detroit Tigers by a single game. The Browns were steadied all year by a staff of colorful characters--Nels Potter, Jack Kramer, Bob Muncrief, Sig Jakucki, and Denny Galehouse--who won big games throughout the season, until after forty-four years, the American League’s St. Louis franchise found itself in the World Series.

The other occupants of Sportsman’s Park, the St. Louis Cardinals, won their third pennant in a row, establishing themselves as the best team of the World War II era. Led by their incomparable young star, Stan Musial (197 Hits, 51 2B, 14 3B, 94 RBI, .347), the Cards annihilated their National League rivals on their way to a 105-49 season record. With Mort Cooper (22-7, 2.46 ERA), Ted Wilks (17-4, 2.64 ERA), Max Lanier (17-12, 2.65 ERA), and Harry Brecheen (16-5, 2.86 ERA) buzzing through hitters like P-51 Mustangs, St. Louis was never tested, spending only four days out of first place all season and recording the most one-sided National League pennant race in forty years.

Dispatching the overmatched Browns in a six-game World Series, the Cardinals stood atop the baseball world, until outfielder par excellence Musial became Seaman First Class Musial and missed the 1945 season. Musial credited his time at the Bainbridge Training Center in Maryland with helping him become a power-hitter. It was there that Musial altered his batting stance and developed the skills that would make him a Hall of Famer who pummeled National League pitching until his retirement in 1963.

Diamond Mind Baseball is pleased to pay homage to these Wartime ballplayers, many of whom have been forgotten in the twenty-first century. Indeed, the 1944 season was a different world that offered a unique, but exciting, brand of baseball. With our new 1944 season, Diamond Mind allows our customers to travel back to the era of Rosie the Riveter, Victory Gardens, War Bonds, Big Bands, and—most of all--the heroism and sacrifice of America’s Greatest Generation.

The 1944 Deluxe Past Season database contains everything you need to play games using teams and players from the 1944 season -- a full set of ratings and statistics for every player who appeared in the big leagues that year, plus team rosters, manager profiles, ballpark ratings, transactions, and league schedules. Statistics include official batting, pitching and fielding totals with left/right splits for all batters and pitchers.

1967 Deluxe Past Season with transaction and lineups available now!

1967: The Summer of Love, Music, and Incredible Baseball

by Steve Ehresman

In 1967, America, torn apart by the Vietnam War, experienced an earthquake of social change, musical creativity, and, for those who were still paying attention, fabulous baseball.  While a staggering 475,000 Americans risked death in Southeast Asia, LSD guru Timothy Leary urged disaffected youth to “tune in, turn on, and drop out.”  Riots ignited in inner-cities.  Rebellion simmered on college campuses.  America wobbled on her axis.  Nineteen sixty-seven was an exhilarating, bewildering, and terrifying year to come of age in America.  

A Human Be-In took place in San Francisco, launching the careers of Jefferson Airplane, The Grateful Dead, and Big Brother and the Holding CompanyThe Doors were banned from The Ed Sullivan Show for their uncensored version of “Light My Fire.”  The Who destroyed their instruments on The Smothers Brothers Comedy Hour.  Jimi Hendrix emerged as a dazzling talent.  Not to be upstaged, The Beatles released both Sergeant Pepper’s Lonely Hearts Club Band and Magical Mystery Tour.  Overnight, the 1960s had transformed from “mod” to “psychedelic.”    

Oh yes.  The baseball was pretty good, too.

While the St. Louis Cardinals, led by MVP Orlando Cepeda (37 2B, 25 HR, 111 RBI, .325) stolen base king Lou Brock (52 SB), consummate hitter Curt Flood (.335), and gritty World Series hero Bob Gibson (13-7, 2.98, and 3 complete game World Series victories), made short work of the National League, compiling a 101-60 record to breeze to the pennant by 10.5 games, the American League put on a show for the ages.  Junior Circuit MVP Carl Yastrzemski of the Boston Red Sox (112 R, 189 H, 44 HR, 121 RBI, .325) won a Triple Crown and powered his team to an improbable pennant.

Only 8,324 turned out at Fenway for Opening Day 1967, demonstrating that the expectations for the Red Sox were low and that their pennant chances were . . . well . . . impossible.  Led by a cast of unknowns, the Sox defied the pundits, delighted their faithful, and edged out the Detroit Tigers, the Minnesota Twins, and the Chicago White Sox “to dream the impossible dream” and create the stuff of legends in Beantown. 

Jim Lonborg led the Red Sox pitchers (22-9, 246 K, 3.16), capturing the American League Cy Young Award.  Tragic figure Tony Conigliaro (20 HR, 67 RBI, .287) helped outfield mate Carl Yastrzemski hammer opposing pitchers, until a horrific beaning on August 18 ended his season and curtailed his promising career.  Youngsters Rico Petrocelli (17 HR) and Reggie Smith (15 HR, 16 SB) combined their talent and energy to push the Bosox across the finish line in baseball’s version of The Great Race.       

The 1967 season witnessed the debuts of Minnesota Twins star Rod Carew (.292) and New York Mets ace Tom Seaver (16-13, 170 K, 2.76).  In addition, reliable anchors like batting champion Roberto Clemente (.357), Cy Young winner Mike McCormick (22-10, 2.85), earned run leaders Joe Horlen (2.06) and Phil Niekro (1.87), strike-out artist Jim Bunning (253), and stolen base king Bert Campaneris (55 SB) all made stellar contributions to the 1967 baseball season. 

The Impossible Dreamers of Boston and the Red Birds of St. Louis made indelible impressions on America’s baseball history, as well as lifetime of memories for their fans.  Amid the swirling confusion of 1967, these championship teams stand out as examples of grace under pressure and consistent excellence.

The year 1967 resists easy interpretations.  America herself has always resisted easy interpretations, consistently emerging from turmoil as a nation greater than the sum of her many parts.  Through it all, baseball has offered a window into our past and a glimpse into our future.  Through it all, baseball has captivated and inspired millions.    

Diamond Mind Baseball is pleased to offer this historic season to its customers.  As the 50th anniversary of the 1967 season dawns, Diamond Mind invites you to remember our heroes from long ago and to revisit their remarkable achievements in our brand new version of this unforgettable baseball season. 

The 1967 Deluxe Past Season database contains everything you need to play games using teams and players from the 1967 season -- a full set of ratings and statistics for every player who appeared in the big leagues that year, plus team rosters, manager profiles, ballpark ratings, transactions, and league schedules. Statistics include official batting, pitching and fielding totals with left/right splits for all batters and pitchers.
