The Arizona Diamondbacks, like the Colorado Rockies and many other teams, have a few key players on their team that will soon become free agents.
For the Diamondbacks, those free agents include their ace Patrick Corbin, center fielder A.J. Pollock, third baseman Eduardo Escobar, and (potentially) their star first baseman (and perennial NL MVP candidate) Paul Goldschmidt.
The D’Backs do have a team option for $14.5 million for next season and they will almost certainly exercise it. However, they have to determine on whether or not they will rebuild/retool their team.
