Average Errors per Game

The SOM basic fielding chart seems to produce a lot of errors, at least compared to TPB. Reality check: what’s the average number of errors per game in MLB? A quick Retrosheet hack gives the average over the years. It’s not a perfect count—multiple errors during one play are all counted as one.

Is the drop due to a change in fielding prowess or a change in official scoring? I reckon it’s the latter.

Chadwick organization

Tried a 1982 TBP game using Chadwick only. Procedure: copy *.ROS files from nl & al Retrosheet folders; copy one TEAM1982 file (both contain both leagues); zip those; open with Chadwick. Looks like event files are created automatically. No need to use a *.chw file.

To edit a .EV* file, open from Compressed Folder, edit, save outside Compressed Folder, copy to Compressed Folder.

Tough without a scoresheet: keeping track of stamina, keeping track of unearned run(ners), W/L/S pitchers. In the last case, editing may be necessary in complex situations.

Baseball board games at the HOF

Century of baseball board games to open April 12

Exhibit features collection of 100 years of leisure entertainment, 1860s-1960s

National Baseball Hall of Fame and Museum

COOPERSTOWN, N.Y. — For anyone who’s ever said, “baseball is just a game,” a collection of baseball board games, soon to be featured in a temporary exhibit at the National Baseball Hall of Fame and Museum in Cooperstown, N.Y., will show that the passion for the national pastime has deep origins and strong roots as a leisure-time activity in American culture, featuring more than 50 games over a 100-year period from 1860-1960.

Chadwick on Windoze

Downloaded Chadwick 0.4.0 for Windoze & also the 0.5.0 utilities. Everything runs nice.

Now, how to organize teams from different years. Everything’s based off the season year. I picked 2008. You need a TEAM2008 file. For Group A this looks like:

BAL71,A,Baltimore,1971 Orioles
NYN73,N,New York,1973 Mets
OAK72,A,Oakland,1972 Athletics
ATL69,N,Atlanta,1969 Braves
CIN64,N,Cincinnati,1964 Reds
MIN69,A,Minnesota,1969 Twins

I added the last two digits of the actual year to the team ID and put the full year in the nickname field. I copied in the Retrosheet roster files, but renamed them to have the team IDs and 2008:

ATL692008.ROS
BAL712008.ROS
CIN642008.ROS
MIN692008.ROS
NYN732008.ROS
OAK722008.ROS

Zipped up the team & roster files into 2008.zip and opened that (open, not import) from Chadwick. Works!

Hit & Run strategy

Played a 1973 game and put the hit & run on at every opportunity. Of 18 opportunities, the H&R affected six plays: four yielded base advancement (three on singles, one on an RG; none scored), one was neutral (K to foul out), and one turned a game-tying home run into a foul out! Final: Braves 3, Cards 1. Atlanta scored on three solo shots; two by Aaron & one by Dusty Baker.

Home-field advantage and Park Effects

Following up on the previous post about home-field advantage, I got the MLB batting splits for the last five years from BR.com, which are summarized in the table below. (Here are the 2007 splits.)

The biggest effect is that the home team strikes out less. The next largest is more walks for the home team. To capture these effects, we need at least 12 rolls, which is an almost perfect fit into the 16 Park Effects rolls, something suggested by the Commish. A possible Park Effects replacement chart appears below. Since the Park Effects range is identical for every batter, we can eliminate the second roll and simply read the result from the original roll that landed us on Park Effects.

I worked in a couple of things that don’t otherwise tend to happen in the ABL: infield pop outs (pointed out by cnc14) and extra advancement on hits.

One could argue that the home team should have a few SF rolls to account for the extra sac-fly production.

This chart would produce a little more offense. A quick calculation shows that a Park Effects roll on this new chart would yield an average of 0.6 bases per roll, whereas the TBP chart yields only about 0.3 bases per Park Effects roll.

Series 3: Las Vegas

Vegas was trying for the jumps in game one—ended up with one SB & one CS. 19 singles in the game, no homers. Brought in Timlin, he walked the first batter, pulled Timlin. (That H symbol!)

TV   101 000 020   4 12 0
LV   000 200 000   2 12 0

Game two was back and forth early. Four homers, three HBP. Blalock made errors on consecutive plays, one a two-base error. Two unearned runs resulted.

TV   012 120 020   8 14 3
LV   203 000 000   5 11 0

Only two symbols: one B apiece for Lilly & Shields.

Tits to 4-2.
