Here are the charts for runs allowed last season. As you can see below, the Sox pitching ended up right around league average. I guess it only seemed worse. Actually, it started out fine but got worse as the season went along. I plan on looking at that in more depth in a future post. For now, I'll just say that the pitching was below average after April and May and you can't see that in the chart.
Overall, the Sox pitching staff would have been expected to win 82 games if combined with a league average offense.
Runs Allowed Distribution
As we saw in the last post, the Sox offense was much better than league average, which is why they won 90 games and not 82. The chart belows shows that they outpaced the league average in winning percentage for just about every run distribution point.
Now I need to add the Sox play in a pitchers park, so you might want to adjust these numbers accordingly. However, the Sox actually gave more runs on the road, so the park didn't seem to play that large of a role.
It seems a bit odd that the Sox would give up more on the road than at home, especially considering the AL Central has a few pitcher's parks in Cleveland, Detroit and Kansas City (and I remember a low scoring series in Fenway, a hitters park). Just another of baseball's many mysteries.
