Following a landslide victory for 2012 Miguel Montero in the catching election, and a similarly large victory for 2001 Mark Grace in the backup first base election, we move on to second base.
Second base is unique among positions in that no single Diamondback has multiple seasons in the top-five by fWAR; in fact, the top seven seasons at second base (minimum 200 plate appearances, as in other articles in this series) are all unique. Aaron Hill's 2013 season, in 8th place, is the first repeat. So the seasons that follow are the top-five seasons at second base, by fWAR, in Diamondbacks history.
