The Seattle Mariners are just two games into the 2026 season, but already their bullpen is stealing the spotlight-perhaps more than they’d like. Since their rise to prominence in 2021, the Mariners' bullpen has been a reliable force. However, last season saw a dip in performance, with the bullpen ranking only in the top 10 for ERA and lagging behind in WHIP, batting average, and strikeouts.
In 2025, the bullpen had its stars like Andrés Muñoz and Matt Brash, and emerging talents such as Gabe Speier and Eduard Bazardo. Yet, injuries and a lack of depth became problematic, climaxing in a tough playoff loss where Bazardo surrendered a crucial three-run homer in Game 7 of the ALCS against the Blue Jays.
This led to a bold move by the Mariners, trading top catching prospect Harry Ford to the Nationals for Jose A. Ferrer-a decision that’s still under scrutiny.
Fast forward to the 2026 season, and manager Dan Wilson is already under the microscope for his bullpen decisions. In the home opener, Ferrer initially looked solid, maintaining a 3-3 tie through the sixth.
But when Speier took over in the seventh, things unraveled. Despite Speier's impressive previous season, he struggled against the Guardians, giving up a two-run double to Jose Ramirez that shifted momentum.
Critics were quick to question Wilson's choices, especially in the seventh inning. Yet, it’s hard to pin the blame solely on him when Speier allowed hits against batters who typically struggle against lefties. Some argue that Brash should have been brought in against Ramirez, but Wilson’s decision to back Speier was likely an effort to boost his confidence early in the season.
Friday night, however, painted a brighter picture. Despite managing only three hits, the Mariners secured a 5-1 victory.
The bullpen shone as Bazardo, Brash, and Muñoz each delivered scoreless innings, sealing the win. Wilson expressed relief, noting the bullpen’s strong performance and their aggressive approach.
Adding to the bullpen narrative, righty Carlos Vargas was placed on the 15-day injured list with a right lat strain, prompting the recall of Cole Wilcox from Triple-A Tacoma. Vargas’ absence is a blow, given his potential despite erratic moments last season. Wilcox, once a top college prospect, brings intrigue with his high-velocity fastball/sinker combo.
As the season unfolds, Wilson will undoubtedly face more scrutiny regarding his bullpen management. Yet, with the talent at his disposal, the Mariners have the tools to navigate these challenges and support their manager through the ups and downs.
