Recent Form
Seattle Mariners
Seattle’s 61‑68 record tells the story of a team that can light up the scoreboard but often fizzles when it matters most. After dropping the final two games of their road trip, the Mariners have rallied to win three of their last five at home.
- Starting Pitcher – Kade Anderson (0‑0, 0.00 ERA) is set to make his first major‑league start. The left‑hander’s dominance in the minors has generated a buzz in Seattle’s dugout, and fans are eager to see if his “lights‑out” command translates to the big leagues.
- Offense – Julio Rodríguez continues to be the spark plug, batting .298 with 22 homers. The middle of the order, featuring Mitch Garver and Ty France, has been productive, but the bottom three have struggled to drive runs consistently.
Chicago Cubs
The Cubs have endured a roller‑coaster stretch, slipping to 58‑71 after a 4‑1 loss in their most recent series. Yet, they have shown flashes of resilience, winning four of their last six games.
- Starting Pitcher – Jameson Taillon (5‑7, 3.78 ERA) will take the mound for Chicago. Despite a rocky start to the season, Taillon has settled into a rhythm, striking out a league‑average of 8.5 batters per nine innings.
- Offense – Cody Bellinger has rediscovered his power, belting 18 home runs and driving in 55 runs. Meanwhile, Ian Happ has been a catalyst at the top of the order, posting a .285 average and a .380 on‑base percentage.
Both squads are riding on uneven waves, which makes this Saturday showdown all the more intriguing.
Key Players & Units to Watch
| Team | Player | Why They Matter |
| Mariners | Kade Anderson (LHP) | Making his MLB debut, his fastball sits in the high‑90s and his slider has been a swing‑and‑miss weapon in Triple‑A. |
| Julio Rodríguez (CF) | The franchise’s cornerstone; his blend of speed and power can change a game in a single at‑bat. | |
| Mitch Garver (C) | Provides a steady presence behind the plate and a pop‑up bat that can drive in runs in clutch moments. | |
| Cubs | Jameson Taillon (RHP) | A veteran who can eat innings; his ability to locate pitches on both sides of the plate will test Anderson’s inexperience. |
| Cody Bellinger (LF) | After a slow start, he’s now a 20‑home‑run threat. Expect him to look for extra bases early. | |
| Ian Happ (RF) | Leads the Cubs’ offense with a high on‑base percentage; his patience will wear down the Mariners’ bullpen. |
Bullpen Battle – Seattle’s relievers have posted a collective ERA of 4.45, while Chicago’s bullpen sits at a more respectable 3.87. If the game gets tight, the Cubs’ back‑end could be the decisive factor.
Head‑to‑Head Record
The Mariners and Cubs have a long‑standing rivalry that stretches back to Seattle’s inaugural season in 1977. As of the 2025 season, the two clubs have met 253 times, with Chicago holding a slight edge: 134 wins to Seattle’s 119.
- Last 5 meetings (2022‑2025): Cubs 3‑2. The most recent encounter saw Seattle pull off a dramatic 6‑5 victory, highlighted by a two‑run homer from Alex Bregman (who was briefly with Seattle in a mid‑season trade).
- Series in Seattle (2024): Mariners won 3 of 4 games, showcasing the advantage of the Pacific‑time fan base.
While the overall series is close, the Cubs have historically performed better in October, a fact that could matter if the game comes down to late‑inning pressure.

Prediction
Both teams have something to prove, but the numbers tip slightly in Chicago’s favor. The Cubs’ bullpen is tighter, and their offense has been humming after a mid‑season resurgence. Seattle’s starting pitcher, Kade Anderson, is untested at the major‑league level, and while his stuff is impressive, the pressure of a debut could lead to early runs.
Projected Score: Chicago Cubs 5, Seattle Mariners 3
*Why?* The Cubs are likely to capitalize on the Mariners’ middle‑order inconsistencies, while the Mariners’ power hitters could keep the game close. Expect a tight contest that may be decided in the seventh inning when Chicago’s relievers take over.
