The Seattle Mariners are entering the 2026 season with sky-high expectations after coming within eight outs of their first World Series appearance in franchise history last year. With a roster stacked with future Hall of Famers, All-Stars, and promising prospects, the Mariners are the prohibitive favorites to repeat as AL West champions and make a deep playoff run.
Why it matters
The Mariners have historically fallen short of expectations, but this year's team is loaded with talent and poised to end the franchise's World Series drought. A successful season would energize the fan base and cement the Mariners as a perennial contender in the American League.
The details
The Mariners' lineup features five All-Stars, including superstar outfielder Julio Rodríguez, who is poised for a 40-homer, 40-steal season. Catcher Cal Raleigh, fresh off a historic 60-homer campaign, is expected to remain one of the game's most valuable players. The pitching staff is led by ace Bryan Woo and the X-factor George Kirby, who the team believes can be their most valuable arm. The Mariners also added Brendan Donovan, a high-OBP threat, to set the table for the middle of the order.
- The Mariners won the AL West with 90 wins in 2025.
- The Mariners came within eight outs of their first World Series appearance in franchise history last October.
The players
Julio Rodríguez
A 25-year-old superstar outfielder poised for his first 40-homer, 40-steal season and a run at the AL MVP award.
Cal Raleigh
The Mariners' star catcher, fresh off a historic 60-homer season, is expected to remain one of the game's most valuable players.
Bryan Woo
The Mariners' ace, coming off his first All-Star season and a top five AL Cy Young finish, is one of the most important figures on the roster.
George Kirby
A talented right-hander who the Mariners believe can be their most valuable pitcher in 2026 if he stays healthy.
Brendan Donovan
A high-OBP threat acquired in a trade, he will bat atop the Mariners' loaded lineup and likely open the season as the starting third baseman.

“There has never been a better time to be the Mariners.”

“Julio Rodríguez, at age 25, will have his best season yet - poised for his first 40-homer, 40-steal season.”
— Adam Jude, Sports Writer (bellinghamherald.com)
What’s next
The Mariners will look to build on their success from last season and make a deep playoff run in 2026. All eyes will be on the team's young stars, like Julio Rodríguez and Cal Raleigh, to take the next step and lead the Mariners to their first World Series championship.
The takeaway
The Mariners have assembled a roster capable of winning a World Series, ending decades of frustration for the long-suffering fan base. If the team's young stars continue to develop and the pitching staff stays healthy, the Mariners could be poised for a historic season and a return to the Fall Classic for the first time in franchise history.
