I just watched the replay of the call in question again, and, to me, it seems like an awful call. For one, he was not outside the baseline as ORS stated. Second, to say he showed intent is just wrong. He was running a straight line without looking back. I don't see how he could have intentionally made contact with the baseball.
On top of that, the play happened at the bag, meaning it didn't matter what route Cano took to get to the bag (see Game 2 1998 ALCS judgement involving Travis Fryman and Chuch Knoblauch).
I was citing this play because I felt like it was a series changing play that went against the Yankees.
As for the umpires showing bias towards the Yankees, you cited one game. Unfortunately right now I don't have the time to do the research on the other 12 games that took place between 2005 and 2007. However, I admit I'm not in any position to question your analysis because I haven't done any of the appropriate research.
And as for the fact that it's easier to cover up in the regular season, that's true, but if teams felt they were at a disadvantage when they were playing the Yankees (regardless of whether it is the regular season or the postseason) you would think they would mention it. Because of this, it is extremely risky to do it in the regular season or postseason in my opinion. All it would take is one team to mention it and everyone would be thinking about it.
