let's review here: the brewers have some pretty good fielders (hardy, hall, cameron), some average ones (kendall, hart), a guy who has apparently improved a lot (weeks) and two lousy fielders (prince, braun). weeks is gone now, so they'll be replacing him with a guy who can't hit but is good defensively (counsell) or a guy who will probably hit well, but is atrocious in the field (gamel). yet they're ranked #2 in baseball with a .724 DER, which would be better than any major league team in history. Last year they were #7 win baseball with a .698 DER, with roughly the same team. exhibit #2, let's wade through their results on balls in play. Throwing out the two guys with BABIP's over .500 because they've collectively pitched 2 1/3 innings, all but two members of their pitching staff have a BABIP below the league average of .299. Some are very far below it, like Hoffman, Bush and Gallardo. The only guy who would expect to have a very low BABIP is Stetter, as a LOOGY with a low LD%. Hoffman has a 20.7 LD% the past 7 years; this year it is 8.7%, which is not likely to be sustained given that he's an old dog and probably hasn't learned any new tricks. Bush, Gallardo, McClung, Looper, Villanueva - all with anomalously low BABIPs that do not match up with their career track records and their batted balls this season. Suppan actually has only a 12.2 LD%, but that is far out of line with his normal 20% and will not be sustained. The two guys with higher BABIPs, Parra and Coffey, are actually right about in line with their career BABIP and projected BABIP by Zips. Lastly, take a look at these team stats. As mentioned above, the Brewers have an extremely high DER. They also have one of the highest LOB% in baseball (74%). Their ERA of 3.89 way below their FIP of 4.51. Given that they have roughly the same position players as last season, and also have a number of pitchers with a wealth of evidence as to what type of pitcher they are, I can't conclude that the Brewers have become one of the best defensive teams in major league history, nor can I believe that their pitchers have collectively learned how to pitch very effectively to contact. Rather, it looks to me like they've simply been very lucky through the first month and a half of the season, and once that luck runs out, they'll regress to being a team that is average at run prevention.
