Luck Balancing?

4 Wookies 44 62 .415 42 64 .400


Well my hopes of Luck Balancing seem to have not panned out. The TriBonds have incredibly INCREASED their wins-over-pythagorean to +11!!! while I've stayed mired in about the same hole, -6. Matt has slipped to -6 himself but is having a great season anyway. My other division rivals maintain their small bonuses of +4 and +2 while Ken and Lou continue to underperform at -2 and -4.


Scoshe offered this gem in these latest results that might have been addressed to me personally...



Run Differential: Over the years many baseball studies have been done on how 'run differential' (the difference in runs scored versus runs allowed) relates to won-loss record. Given the interest in that subject we'd like to give our thoughts on run differential, and how it compares in Scoresheet to the majors.

Certainly scoring runs is a good thing for your offense, and giving up the fewest runs possible is the top goal of your pitchers and fielders. However, in both the majors and in Scoresheet, run differential is not a perfect measure of won-loss record. Some teams simply perform better in close games (maybe they have a better late inning bullpen, or maybe they have more speed and can manufacture that one crucial run, or maybe they are just plain lucky?), while other teams are set up to simply blow out the opponents (often the teams who live and die by the HR, and so score in bunches).

In general a league's standings do roughly follow run differential. But there have been some pretty large differences between won-loss records and run differential in past major league pennant races, and also in Scoresheet races. And in Scoresheet, there are a couple of reasons why run differential is definitely a worse predictor of won-loss records than in the majors. There are a few more blowouts in Scoresheet than in the majors - use of AAA pitchers can really lead to some dismal scores! Also, in the majors, once a team gets way ahead they seem to quit trying as hard - the players want to get it over with. In Scoresheet, if your hitters are facing lousy pitching they are 'supposed' to get more hits, so they keep pounding away. Winning or losing a blow out (something like 18-2) only counts as one win or loss, but it can really distort a team's run differential.

Also, here is what I always feel may be the biggest reason for won-loss records not matching up well with overall run differential: if you have a Scoresheet team with 3 really good starting pitchers, and 2 horrible ones, you may win about 3 of 5 games, but there is a good chance your 2 lousy pitchers will lose by big scores, while your 3 good ones may be winning close games (meaning you'll have a bad run differential but a good won-loss record.) If you have a lot of HR hitters you may win a lot of blowouts, but in games where you don't hit HRs you may be losing a lot of close, low scoring affairs (meaning you'll have a good run differential but not necessarily a great record.) All of these reasons can help account for why your won-loss record can not be perfectly predicted by your runs.

Since in both Scoresheet and in the majors, it is won-loss record that determines who comes in first place, then W-L record is what you really care about. If you think your team should be winning more games then take a look at the various stats we print each week with the standings, or the 'won-loss' breakdown table we printed every two or three weeks, and see if there is some subtle things other teams are doing that you seem to be lacking in (steals, sacrifices, saves?) Winning or losing close games does involve some luck, but managerial strategies, and the kind of team you put together, do matter a lot. For instance, having no good closer can really hurt in the close one run games in the ninth inning.


Oh well, there's always next year. Maybe my "no good closer" is the difference of 17 games.
