San Diego Padres – Chicago Cubs

San Diego secured 90 wins and home-field advantage after a 10–7 victory over Arizona on September 26, 2026, with an offense capable of capitalizing on mistakes and early bullpen usage. The Padres also had a 51–30 record at Petco Park, according to their FAQ published on September 27.

Detailed data on recent form and the weather verified before the game have not been established. Chicago had won five of its six regular-season games against San Diego, including two of three at Petco Park, but this series does not replace the evaluation of the pitchers and lineups on September 30.

In the 2026 regular season, the Cubs won five of the six matchups against the Padres, including two wins in three games at Petco Park and a sweep in Chicago, according to the Cubs' FAQ published on September 27, 2026. The individual scores and precise dates of these games are not documented here.

This record indicates a recent advantage for Chicago, but its predictive value is limited by the change in playoff context, unconfirmed pitchers, and uncertain availability.

For San Diego, Jeremiah Estrada was probably unavailable in the short term due to shoulder discomfort, and Jason Adam could have had a limited workload. For Chicago, Kevin Gausman remained under observation after a left shoulder injury, and Edward Cabrera's availability was not established after he was placed on a list related to bereavement or a family emergency.

The final status of the players and pitchers concerned remains to be confirmed.

San Diego can impose a low-scoring game by relying on Petco Park, its 51–30 home record, and a bullpen described as a major strength; however, this scenario depends on the starter ultimately selected and on how Game 1 is used. Chicago can extend its recent head-to-head advantage through its rotation and bullpen flexibility, but must do so on the road, without a designated closer and with several uncertain availability statuses.

Game 2 is scheduled for September 30, 2026 at 7 p.m. PT; the time corresponds to 02:00 UTC. Weather conditions and the state of the field remain to be confirmed.

The starting lineups for both teams have not been published. The Game 2 starting pitchers have not been announced: Nick Pivetta was San Diego's likely candidate after returning from a five-month absence related to a flexor strain, while Chicago was considering Clay Holmes, David Peterson, and Shota Imanaga, among others.
