The Arizona Diamondbacks and the San Diego Padres are set to face off in a pivotal three-game series at Petco Park, commencing Friday, September 25, 2026. This matchup carries significant implications for both teams as they approach the conclusion of the regular season.
Padres' Playoff Positioning
The Padres have secured a postseason berth, marking their third consecutive playoff appearance. However, their focus remains on clinching the top National League Wild Card spot to ensure home-field advantage in the upcoming Wild Card series. Currently, they hold a one-game lead over the Chicago Cubs for this position. Maintaining this lead is crucial, as it would allow them to host the Wild Card series at Petco Park. (cbssports.com)
Diamondbacks' Playoff Aspirations
Conversely, the Diamondbacks are in a more precarious situation. With an 85-74 record, they trail the Philadelphia Phillies by two games for the final NL Wild Card slot. To keep their postseason hopes alive, the Diamondbacks must win at least two of the three games against the Padres and rely on the Phillies losing two of their remaining three games against the Tampa Bay Rays.
