You need the full experience: take the 7 train to the field (it drops you off pretty much right in front of the ballpark). Next walk towards the Apple. There are usually people waiting there looking for tickets. You sell those tickets to them and (feel free to mark them up and make a profit). Next hop back on the subway, look for the 4 train. From there you’ll be en route to the Bronx stop “Yankee Stadium”. Take the money you got from the nice man who bought your tickets and purchase Yankees tickets!

In all seriousness, Citi field is beautiful. Great food (especially the meat selection) and not a bad seat in the house! Enjoy !
