Rising playoff prospects for the Mariners unfold post-trade deadline, as reported by M's Extra.
Mariners Bolster Playoff Prospects with Shrewd Deadline Moves
The Seattle Mariners have made a significant impact on their playoff prospects following the 2025 trade deadline. By acquiring key players such as Eugenio Suárez, Josh Naylor, and Caleb Ferguson, the team has bolstered both their offense and bullpen, positioning them as one of the strongest contenders in Major League Baseball heading into the postseason [1][2][3].
The Mariners' front office executed shrewd deals that enhanced their lineup, featuring the league’s top home run duo Cal Raleigh and Eugenio Suárez, and improved bullpen depth. Unlike many teams, Seattle managed to improve without weakening their farm system, a feat that is relatively rare and noteworthy [2][3].
Some other contenders also made impactful moves, such as the Astros reacquiring Carlos Correa and the Athletics trading closer Mason Miller for a top prospect. However, none matched Seattle’s blend of upgrading key positions while maintaining prospect depth [2].
The Mariners' chances of making their first-ever World Series appearance are considered high following these moves, as they approach near full health and have added promising pitching talent in rehab assignments that could soon join the major league roster [1][3].
One of the Mariners' top prospects, Ryan Sloan, is ranked No. 90 in the Baseball America Top 100 prospects list for Low-A Modesto. Lazaro Montes, another Mariners prospect, is ranked No. 39 in the Baseball America Top 100 prospects list for AA Arkansas. Michael Arroyo, Colt Emerson, Jurrangelo Cijntje, Harry Ford, Jonny Farmelo, and Kade Anderson are also ranked in the Top 100, further demonstrating the strength of Seattle's farm system [1].
The Mariners' playoff probability increased by 6.2% at the trade deadline, according to updated projections from FanGraphs' ZiPS model. This improvement places them among the top playoff contenders, with a current playoff probability of 7.9% [1].
However, the team suffered a setback with the loss of Trent Thornton for the season. Despite this, the Mariners remain optimistic about their postseason prospects [1].
In comparison, other teams have had mixed results. The Dodgers traded away one of their few healthy arms (Dustin May to Boston), while the Twins surprised the industry with a sudden roster selloff at the deadline. On the other hand, Texas had a successful deadline, landing an underrated starting pitcher (Merrill Kelly) and two bullpen arms (Phil Maton and Danny Coulombe) [1].
The American League teams' probability to win the World Series, per FanGraphs' model, is as follows: Blue Jays (7.1%), Yankees (8.8%), Mariners (7.9%), Astros (6.3%), and Tigers (7.8%) [1].
Randy Arozarena, meanwhile, continues to impress, joining the 20 homer/20 steals club for the fifth consecutive season. His performance has reinforced the Yankees' bullpen in a big way [1].
In other news, the new ownership group can't take over soon enough in Minnesota, and San Diego swung the most surprising trade at the deadline by landing A's closer Mason Miller [1]. Kade Anderson, drafted by the Mariners, has made his debut in the Baseball America Top 100 prospects list at No. 31 [1].
Lastly, Tyler Locklear, the key prospect the Mariners sent to the D'backs in exchange for Eugenio Suárez, made his debut for the Arizona Diamondbacks on Friday night [1].
