Astros might be best team since 1927 Yankees

It is .167 thru Friday, Sept. 27. Their team OPS is .847 and they have allowed .680. If they finish with that, it will be the 2nd highest since 1908, trailing only the 1927 Yankees. The Astros will easily have the highest differential of any team since 1939.

In the first half (90 games), their differential was .123. In the 2nd half (70 games) it has been .222. The 1927 Yankees had .201 for the whole season.

Here is a link to the rankings I compiled using the Baseball Reference Play Index.

Update Sept: 30: The Astros finish with .167. Just to make sure they are still above the 1913 A's, I did OBP and SLG to several decimal places (to check rounding issues). The results are in the table below, although it looks like Baseball Reference does not count sacrifice hits in PAs in 1913 but does include SFs in 2019 (back in 1913 there was not distinction). The Dodgers finished with .149, which will make them the 7th best team since 1908 (but I did not look for rounding issues to compare them to the 1922 Browns to see if they might be better).
