As a person who has seen a fastball and a sinker - they are NOT the same pitch. One moves down, the other moves sideways. If you DVR'ed the game, go back and watch the pitch again. That ball moved down and away from Dunn like a screwball. That's a very tough pitch to handle.
two seam fastball moves down and away. a two seamer is essentially a sinker.
not many sinkers just go straight down, they usually move in towards a RH batter too (thrown by a RHP).
