The Chicago Cubs enter the series at T-Mobile Park with a 74-56 record, sitting second in the NL Central and pushing for playoff positioning, while the Mariners stand at 62-68 in third place in the AL West. Seattle has taken the first two games in walk-off fashion, including Randy Arozarena’s game-ending two-run homer on August 22 and Leo Rivas’ RBI single the prior night. Upcoming pitching matchups feature Shota Imanaga against Bryce Miller for the finale, with both clubs dealing with recent form swings and road/home splits that favor the Mariners in their home environment. Roster health and bullpen usage remain key variables for the remaining contests.
