Pushing the two seam

when i watch major leaguers such as halladay and mussina, it looks like they try to push the sinker out of their hand

i dont see webb or wang doing that though

halladay and mussina have nasty lateral movement

does anybody know what that is

I thought the sinker and the two-seamer are different pitches? LOL

two seam sinker
they are but im not gonna argue
just go with the flow

it seems like they get more behind the ball

It’s just their different arm actions that make it “appear” they are pushing it or not.
