This comment sparked my interest, so I did some additional number crunching starting with rluzinski's data. I listed every start on the season by the pitchers he classified as bad (Delarosa, Fogg, Rusch, Olsen, Redman, M. Hendrickson, Livian Hernandez, R. Liz, G. Reynolds, Piniero, Moehler, Badenhop, O. Perez (WSN), C. Morton, Nelson Figueroa! and Chacon). I don't put as much stock in projected data, especially since they tend to be a little generous in terms of horrible pitchers (ie they don't project people over 5.5, but many of these guys have ERAs above that in actuality). Here's what I came up with... Weighted Projected ERA: 5.12 Actual ERA Against Brewer Batters: 5.42 2008 ERA Versus All Teams: 5.43 This shows us that the Brewers are in line with all of the other teams against crappy pitchers. But how about the spread of these games and do we have a larger feast or famine tendency as geddymd hinted at? These pitchers have a combined 198 starts on the season. The median is 4.50 on the button. Note that the median is BELOW the actual ERA. This says that poor pitchers have more above average ERA games then below average ERA games. Geddymd is correct by saying the median ERA is 3.38 for these pitchers against the brewers, which may show the Brewers have a tendency to give poor pitcher more above average games then most teams. However, this sample size is only 19 games, and the next ERA after 3.38 is 5.07, which is obviously above 4.50. Therefore, if we have above a 5 ERA against the next poor pitcher start, our median will jump over a point in ERA. Therefore, there is too small of a sample size to do anything with the median, but the data suggests there is no reason to believe our median would be dissimilar to the 4.50 mark with a larger sample size. Also, the mode for the Brewers against these poor pitchers may be 3.00, but surprisingly the mode for these pitchers against everyone is 0.00 (15 of 198 games had 0 ER, 13 had a 4.50 ERA). However, the tendency for certain ERAs for a game to show up more often for nice round numbers (such as 0, 3, 4.5, 6) shows me that mode is not a good analysis tool in this situation. My conclusion is that the Brewers are perfectly average in their performance against poor pitchers, however even poor pitchers perform better then their season averages in the majority of their starts. Therefore the perception is that the Brewers do worse then they should against poor pitchers when they are performing at a perfectly reasonable standard. I would post my data, however I do not have a website to upload to, and it's rather ugly because I only have Microsoft Works Spreadsheet and didn't spend the time to format and pretty it up. Also, please ignore any grammatical errors because I typed this out quickly after crunching the numbers.
