The Story in 60 Seconds

Just Baseball argues that five key Seattle Mariners players must improve next season following a disappointing 76-win campaign and the firing of manager Dan Wilson. After nearly reaching the World Series in 2025, Seattle missed the postseason as major contributors struggled. The analysis highlights Cal Raleigh, Josh Naylor, Julio Rodríguez, George Kirby, and Andrés Muñoz as the core figures needing significant bounce-back performances.

According to the article, Raleigh suffered a steep drop in offensive and defensive production, while Naylor managed only 10 home runs in the first year of his $92.5 million deal. Rodríguez regressed defensively to a -3 OAA, Kirby recorded career-worst walk and strikeout rates, and Muñoz converted 28 of 38 saves while dealing with unfortunate underlying metrics.
