Thirteen players on the Yankees 2015 postseason roster were developed by other teams. In fact, and this might shock you, the Yankees have a bit of a reputation for reaping the performance of players drafted and/or developed elsewhere.

In this piece, I take a look at all seven active players, ranking them in terms of their importance to their current team, and their potential (from lowest to highest) for impacting their new squad’s postseason performance.
