Trade with SpastikMooss

I've lost track how many times I've traded with SpastikMooss of the Great Sports Name Hall of Fame. In my free haul from last month I had a ton of doubles from 1990-1993 Upper Deck which had lots of cup cards for his collection. (Still have a ton of doubles from those sets if anyone has needs there.)

In return he sent me a nice eclectic mix of cards. The most interesting to me was this 2009 O-Pee-Chee, highlighting a pretty random game, a 2-0 Yankee win over Tampa Bay in April of 2008. I don't know much about this set - did they have a card for every game? Or is this just an example of a set cramming as much Yankee stuff in as they can to annoy all the Yankee haters?
