The Chicago Cubs enter the series at T-Mobile Park as the stronger side, holding a 74-56 record and second place in the NL Central while the Mariners sit at 62-68 in third in the AL West. Recent interleague results favor the Cubs' pitching depth and road splits, though Seattle has capitalized on late-inning power with back-to-back walk-off wins, including Randy Arozarena's two-run homer to take a 2-0 series lead. Key factors include the Cubs' probable starter Shota Imanaga against a Mariners rotation still managing pitching injuries, Chicago's recent form despite road travel, and Seattle's home advantage in a park that can suppress offense. Roster health updates, bullpen usage after consecutive close games, and any lineup adjustments for the finale will shape the final outcome.
