One of the things I was curious about was the unfamiliarity factor. Are the Astros just unfamiliar with AL pitchers, and that's why they can't hit? (The unspoken side of this is all the American League teams who are 51-24 against the Astros since the beginning of 2008).
In 2012, the Astros have faced SPs 2+ times on thirteen occasions. Let's take a look, shall we?
Let's look at Average Game Score by all opposing pitchers first, eh?
Average Game Score, the first time the Astros faced them in 2012: 52
And the second time they faced that Starting Pitcher: 49.7
Mike Leake had the biggest swing in Game Score differential with a +39 in the 2nd start (69) to the 1st start (30). Chad Billingsley had a +32, and Carlos Zambrano had a +31. In all, of the 13 pitchers, eight of them - for whatever reason - posted a lower Game Score in their 2nd time facing the Astros than they did the first time. The leaders in minus territory? Randy Wolf (-36), Juan Nicasio (-30), Jeremy Guthrie (-21).
American League SPs have an average Game Score of 60.25, by the way. And Colby Lewis is the only AL pitcher the Astros have seen more than once this year, and he posted a 75 and 76, respectively.
This is not a very in-depth look at whether the Astros will post a record similar to the .320 Win% they have over the past five seasons, but - for one thing - it's hard to lose 110 games - and this 2012 team (whom, it seems, will look familiar in 2013) has fared better the 2nd time around.
Now, feel free to pick this apart.
