can i get a train from here directly to yankees stadium and pay at at the station, Thankyou.

Yes

Of course! You can pay with Tap or metrocard . But just read this carefully because MTA trains have some changes. Catch the D train express here going Uptown & The Bronx until the 145 Street station then get off the D train to catch the B train but on the same track. Now the trif you here the train conductor on the speaker say "D train going LOCAL" then you can stay on the D train to Yankees stadium
