Arizona (84-75) is in position for the second NL wild card and its first postseason appearance since 2017. The Diamondbacks entered two games ahead of the Chicago Cubs and Miami, who were tied for the third and final spot. Arizona would have clinched Thursday with both a win and a Cubs loss at Atlanta.
Each team had three hits, and Arizona went 0 for 5 with runners in scoring position.
Chicago (61-98) is trying to avoid its first 100-loss season since 2018.
Rookie Corbin Carroll had two of Arizona's hits.
Diamondbacks manager Torey Lovullo said the team will make rotation adjustments if it is able to secure a wild card spot but is only focused on clinching playoff berth until that happens.
“I don't care where we land, where we go or who we wind up playing against," Lovullo said. "Getting to the big dance is the most important thing and then we just play our game. We have very talented players and I think we match up with anybody.”
Diamondbacks: A day after he was scratched because of right shoulder discomfort, OF Lourdes Gurriel Jr. was 1 for 4.
Diamondbacks: RHP Zac Gallen (17-8, 3.49 ERA) is scheduled Friday's series opener against Houston RHP J.P. France (11-6, 3.83).
