D’backs Have Faced Slew of Playoff Issues

Besides the franchise’s lone World Series championship (over the New York Yankees in 2001), the D’backs have seen their share of playoff blues since first qualifying for the postseason 24 years ago. In total, Arizona’s six playoff squads have posted a 19-20 record in the postseason, with four series wins against five defeats (four in the NLDS and one in the NLCS).

The D’backs’ last playoff series victory came in 2007, when Arizona swept the Chicago Cubs in the NLDS before facing eventual NL champion Colorado. That best-of-seven series did not go well, with Colorado sweeping the D’backs, en route to a World Series rout at the hands of the world champion Boston.

Fast forward 16 years, and the 84-78 D’backs of 2023 will look to shock the baseball world and energize Arizona sports betting apps, beginning with the team’s series against the Brewers. Based on how Arizona played down the stretch, with the D’backs going 14-12 between Sept. 1 and Sunday’s 8-1 regular season finale loss to the Houston Astros, it seems like any result could occur this week.
