Fernandez entered Tuesday's game in the seventh inning after Nolan Arenado was removed due to a groin injury. Fernandez was hitless in his lone at-bat in a 7-5 win over the Giants.
Arizona manager Torey Lovullo downplayed Arenado's injury to Alex Weiner of Arizona Sports following the game and indicated there were no plans to have Arenado undergo imaging. Arenado is considered day-to-day, and Fernandez is likely to fill in at third base if needed.
