Replacement Level Yankees Weblog has taken several projection systems for the 2008 season, run the season through
Diamond Mind Baseball’s simulator 1,000 times for each system and came up with a
Projection Blowout. They used
CHONE,
Diamond Mind,
Hardball Times,
PECOTA, and
ZiPs projections.
The results are interesting, especially relating to the NL Central division race, which I’ve knocked down to the Cubs and the Brewers. Sorry St. Louis, Cincinnati, Houston, and Pittsburgh fans. I see this as a two-horse race and the projection systems agree.

Some observations:
- This obviously does not mean much of anything, but it is probably the most accurate way we have available to predict the season at this point. These prediction systems, however, have been known to not predict pitching well. They also can’t predict injuries effectively and do not account for major changes in production from players. Take it for what it is, a prediction.
- No matter how you look at it, the Brewers and Cubs are very evenly matched again this season.
- While the Brewers are in first or second in all five systems, they are only first in one, The Hardball Times’ prediction. The Cubs are first in the other four.
- ZiPs loves the Cubs and hates the Brewers. ZiPs predicts the best Cubs’ record and worse Brewers’ record of all the systems by several wins/losses. The system predicts very good seasons for some players that come into the season as question marks for the Cubs (Soto, Pie, and Fukudome). If you take ZiPs out of the equation and average the other four prediction systems, the Brewers finish just a game behind the Cubs, which would mean the season would come down to the final series at Miller Park. That would make for one incredible playoff atmosphere in Milwaukee…
- The four systems besides ZiPs have the Brewers averaging a 42 percent chance of making the playoffs.
- The Cubs are a particularly difficult team to predict. Soto will take over as the full-time starting catcher with almost no major-league experience, Fukudome comes over from Japan with no major-league at bats, and Pie has only limited major-league at-bats as well. Dempster is transitioning from closer to starter and Wood is transitioning from the DL to the closer role. All five of these players will be very hard to project effectively and how much they perform above or below their projections could very easily determine the division.
- I didn't investigate, but I doubt very much that the projections used Sheets, Suppan, Bush, Villanueva and Parra as the Brewers' starting five and I also doubt it used Zambrano, Lilly, Hill, Dempster and Marquis as the Cubs' starting five. Even if it did, Villanueva, Parra and Dempster would be hard to project effectively.
- Almost all of the projections I’ve seen predict the Brewers offense to out-perform the Cubs offense. And almost all of the projections I’ve seen predict the Cubs pitching to out-perform the Brewers pitching. Personally, I think the Cubs pitching is the key to the division. If Zambrano, Hill, and Lilly stay healthy and perform all year and the Cubs don’t have a meltdown in the back end of the rotation (Marquis and Dempster with Lieber waiting in the wings), the Cubs will probably win the division. I just wouldn’t bet on that happening…
It should be another close race... Let the season begin!
Brewer fans, what are your thoughts?
