Of course. Hence the always ridiculous "all things being equal". Good to know I'm (slowly but surely) getting it.

No worries and no issue on my side. I'm a regular reader and contributor here at B-R, so I've read your posts and know you're well-researched and very measured in your responses. That's why I was little surprised that we disagreed in this one area. I admit, in an attempt to discredit the original poster's note, I probably went a little far in trying to show that the NY writers were more fair than he was giving them credit for, so I may have accidently presented an image that reporters outside NY were more biased. That was definitely not my intention.

I certainly don't question any Texas writer for selecting Hamilton, since I believe that Hamilton should have been the MVP. I also don't really have an issue with any Detroit writer picking Cabrera, who had an excellent season. They might be a little more biased since they saw Cabrera every day, but he is still a fine choice. I was simply attempting to show that the NY writers were not as biased as he was claiming.

Even at that exchange or notes, I suspected we actually agreed with each other!

I'm probably as big a Javy Vazquez fan as there is outside his own family, but I thought his return was doomed from the outset. His main weak point is a high HR rate, and Yankee Stadium II seemed like a park where he would give up a lot of HRs -- and he did, witih (gulp!) 18 gopher balls in 66.1 IP. And it was hard to imagine Yankee fans giving him the benefit of the doubt this time around; after getting torched on the road in his first 2010 start, he was booed at home in his next start, despite a decent outing. I wanted it to work out, but I don't think many Yankee fans did.

If there ever is a Round 3 for Javy & the Yanks, I hope it's an odd-numbered year.

I apologize. Everything you said there is right, and I'm sorry. Mine was a dumb, knee-jerk post ... and to top it all off, you were 100% right about the MVP voters from Toronto, Detroit and Texas. Bad day all around for me.

(Sorry to everyone for using this public space for a private purpose.)

It simply adjusts for the run scoring environment, yes?

So, all other things being equal, a pitcher with a 4.00 ERA in the AL with an average ERA of 5.00 would have a 125 ERA+ while a pitcher with a 4.00 ERA in the NL with an average ERA of 4.00 would have a 100 ERA+, yes?

ERA+ is not trying to adjust for league strength.

That does suggest that ERA+ does not do as good a job as hoped when adjusting for league.

It might be the depth in the leagues. If you follow the likes of Keith Law, who reguarly interviews talent evaluators, he believes the weaker NL teams are considered much weaker than their equivalents in the AL. Not all pitchers moving from the NL to the AL might react the same to the increased depth and that may not be reflected in ERA+. Don't know. Just a guess.

So in the 2006 and 2008 seasons when he had a 4.70 ERA in the A.L., but with a 3.80 FIP, his "true" ERA+ might have been in the 120 range, similar to his 2007 season when his ERA and FIP both came in around 3.70. So I'm supporting the notion that, at least during his White Sox days, Vazquez did pitch better in the A.L. than some people believe.

That all said, in addition to the fact the ERA+ doesn't account for fielding, I'm not at all sure it's that useful in determining how a pitcher from one league will do against the competition in another. It's a nice starting point, but I always look beyond ERA+.
