The Mariners will be looking to build off their amazing 2025 and will have an opportunity to do it in front of a large audience
The Seattle Mariners will enter 2026 coming off the best postseason run in the 49-year history of the franchise.
The Mariners made it to Game 7 of the American League Championship Series and were one win away from winning their first pennant in franchise history.
Alas, the Toronto Blue Jays ultimately won the pennant by one run and Seattle was forced to get an early start on building for 2026.
The Mariners re-signed first baseman Josh Naylor to a five-year deal, acquired high-leverage left-handed reliever Jose Ferrer in a trade with the Washington Nationals and signed first baseman/outfielder Rob Refsnyder and backup catcher Andrew Knizner to one-year deals, respectively.
Seattle could also have several more deals in the works. The team is rumored to be one of the main teams engaged in trade negotiations with the St. Louis Cardinals centered around 2025 All-Star Brendan Donovan.
