If you're going to be downtown at all (to see the Statue of Liberty, etc) and want to catch another game, try the Staten Island Yankees --

They are short season class A, so the quality of play is nowhere close to what you'll be seeing up in the Bronx, but it's cheap, great fun, and the stadium has a view of Manhattan at night -- the city is visible behind the outfield bleachers like they have it in Pittsburgh...it's just that you're viewing it from Staten Island.
Best part is, you get to check off taking the Staten Island Ferry which gives nice views of the Statue of Liberty if you're not actually going to visit the statue.

To get there, take the 1 train down from Times Square to the South Ferry stop. You'll get off the train and the ferry is in the next building. This is also where you'd go to see the statue anyways.
I also agree with Steve F -- if you want pizza, get it at Lombardi's. Good stuff. It's thin pizza, but very good.

In general, I would stay away from eating around the Times Square area -- you're going to be missing out on some great food elsewhere in the city. If you want some suggestions, PM me with the type of food you like, and I can give you some suggestions.
Enjoy your trip!
