For no good reason, here's a list of the most frequent trade parters of the Giants. This is both for New York and San Francisco. And while I know the Dodgers and Giants are over 100 years old, and longevity is a factor in this list, #6 still surprises me.
This is all from Baseball Reference's trade database, of course. Before you click over, take a wild guess at the top team. Go on! Guess!
