xBA and The Shift

[DJBeasties]

The Eric Hosmer 2K13 thread got me thinking about xBA and the shift. We always hear about gaps in BA and xBA and you can often correlate hit rates and ball distribution to understand this but when I see people touting in-season BA rebounds for guys like Hosmer or Mark Teixeira because xBA/BA gaps, I know it's more unlikely given the shifts defensively employed against them.

Does anyone know if xBA is taking this into consideration or will? Is it considered just noise at this point? Seems like a flaw.

The infield defense did an extreme shift against Hosmer in about 3% of his plate appearances in 2012. For Teixeira it was over 30%.

KS is that public data?

I don't think Teixeira sends Joe Maddon any Christmas cards

Thanks, KS. So then no on factoring it in to xBA?

I don't know who does xBA, but I doubt they are factoring this in unless they are purchasing the data on shifts. I am also suggesting it probably doesn't matter for Hosmer.

Ok thanks. Appreciate it.
