"We are ecstatic about the tremendous fan support and playoff-like atmosphere for such a crucial series," D-backs team president/CEO Derrick Hall said. "Every game is important and has significant impact on potential postseason play. We look forward to our fans cheering us on to a division title and hopefully home-field advantage at Chase Field."
Tickets are still available for Sunday's game with the Giants as well as Monday, Tuesday and Wednesday against the Dodgers.
The D-backs have sold out two other games this year, Opening Day against the Rockies and Sept. 10 against the Padres.
