Which means to me he throws only 2 seamers, and his get sink. Not all do:

Corbin however doesn't have the same % of fastball to sinkers - he clearly also throws fastballs that don't sink, so either he uses some 4 seamers, or he throws the 2-seamer with slightly different grips:

So where is his 4 seamer in OOTP/PT? PT has been around for 2 years, he's thrown fastballs that don't sink about 20% of the time in those 2 years.

I haven't watched Corbin IRL to see his fastball usage, but fangraphs tends to be pretty accurate with Pitch/fx, so I'm unsure of any further comment with regard to why he doesn't have a 4-seamer in the game. I only know it is not only possible for a pitcher to only have a 2-seam sinker, it's actually pretty common (particularly lefty specialists/GB specialists/sidermers). Beyond that, as I said I do not know.
