The Chicago Cubs (74-56) enter Sunday’s finale at T-Mobile Park with a superior overall record and stronger offense, ranking ahead of the Mariners (62-68) in runs scored, home runs, and on-base percentage while holding a firm NL Wild Card lead. Shota Imanaga (8-9, 3.77 ERA) takes the mound after solid recent outings, facing Bryce Miller (4-7, 3.71 ERA) for Seattle. The Mariners have claimed the first two games of the series via late rallies, including a walk-off on Saturday, but carry a thinner lineup hampered by injuries to J.P. Crawford, Colt Emerson, and others. Multiple Cubs arms remain on the IL, though their depth and road performance since July give them a measurable edge in a low-scoring environment at the Mariners’ home park.
