The Seattle Mariners are coming off arguably the team's most impressive season since it was established in 1977.

The Mariners finished the year with a 90-72 record to finish as the second-seed in the American League. Seattle won its first American League West title since 2001, advanced to the American League Championship Series for the first time since 2001 and made it to Game 7 of the ALCS before ultimately falling to the Toronto Blue Jays. It was the first time in the Mariners' history they were one win away from the World Series.

For his efforts in putting together the team that made the best postseason run in franchise history, Seattle president of baseball operations Jerry Dipoto was named the MLB's Executive of the Year by Baseball America.

"It really was reaffirming that what we all believed was that through a foundation in scouting and player development—what we’ve been able to achieve in those areas—putting together a really strong foundation with our major league club," Dipoto said in a story written by Shane Lantz for Baseball America. " ... This really should just be our coming out party of sorts.”

The 2025 Mariners team was a combination of players drafted/signed and developed by Dipoto and the front office and players acquired during the season.

Of the five players on Seattle's starting rotation, four were drafted and developed by Seattle. Two of the starting pitchers who filled in when members of the rotation missed time, Logan Evans and Emerson Hancock, were also drafted and developed by the M's.

The Mariners also signed starter Cal Raleigh to a long-term extension this offseason. He proceeded to set the MLB single-season record for home runs by a catcher and a switch-hitter with 60.

Center fielder Julio Rodriguez, starting pitcher Bryan Woo and Raleigh comprised three of Seattle's five All-Star selections this past season. All three have spent their entire professional careers with the Mariners organization.

At the trade deadline, Dipoto and the front office acquired first baseman Josh Naylor and third baseman Eugenio Suarez.

Naylor scored 32 runs in 54 games with Seattle and hit 10 doubles and nine home runs with 33 RBIs and stole 19 bases in as many attempts. He slashed .299/.341/.490 with an .831 OPS. He signed a five-year, $92.5 million contract with the Mariners in November.

Suarez hit 13 home runs for Seattle and another three in the postseason.

"It really is not a one-person job," Dipoto said in Lantz's article. "While this one might be singled out as me, it is such a group effort. It’s a village, you know? ... What we’ve been able to do through player development, it just makes me thankful for all the wonderful people who I’ve had an opportunity to work with over these years."
