I consider a sinker a fastball. I have to say though that I looked at the pitch twice and it looked more like a screwball (which is not a fastball) than a sinker. Or maybe it was a two-seam fastball that acted like a screwball? Of course I believe Johnson throws sinkers a lot of the time and probably doesn't even throw a screwball so who knows. I agree with minty though. In that count it looked to Dunn like a good pitch initially but it ended up being a good pitch from the orioles' perspective.
