The Seattle Mariners have seen the fruits of their labor with the farm system over the last several years.
Last year, former top 100 prospect Cole Young received his major league call-up and is currently the team's starting second baseman.
Top 10 prospect Colt Emerson made his major league debut May 19 and has posted an OPS over .800 as the team's primary third baseman.
The Mariners will all but certainly get more boosts from the rest of their top 100 talent over next several months and years, but the the team's bullpen has also benefited from the farm system over the years.
Seattle has a crop of talent at relievers in the minor league that aren't featured on various top 100 lists but are working their way up the farm system and several were promoted recently or working their way back from injuries.
Here's an overview of some talented relievers who were promoted in recent days:
Moore was picked in the seventh round of the 2024 MLB Draft out of Oregon. After struggling in his first full season as a pro and missing time due to an injury (9.64 ERA in 25 appearances in High-A in 2025), the former Duck bounced back this year.
Moore posted a 1.13 ERA and fanned 32 batters in 16 innings pitched across 13 appearances with Everett to start the year.
The 26-year-old was promoted from High-A to the Double-A Arkansas Travelers on Tuesday and made his Double-A debut the same day.
Moore pitched a scoreless inning. He struck out one, walked one and allowed one hit.
Alford has had a long stint in the Mariners' minor league system. He was signed to a minor league contract July 20, 2021, out of Virginia Tech.
Alford has been up-and-down between High-A and Double-A from 2022-25 due to inconsistent results.
This year, the former Hokie is putting together his best year in the pros.
With the Travelers, he posted a 1.42 ERA and fanned 30 hitters in 19 innings pitched across 13 appearances.
Alford was promoted to the Triple-A Tacoma Rainiers on Tuesday.
Like Moore, Alford pitched a scoreless inning with his new club. He struck out two, walked two and allowed one hit in one inning pitched the same day he was promoted.
McGraw is ranked as the team's No. 13 prospect, per MLB Pipeline.
The former Wake Forest Demon Deacon boasts some of the best pure stuff in the organization but has been plagued with injuries dating back to when he was picked in the third round of the 2023 MLB Draft.
McGraw was extended a non-roster invite to spring training this year but didn't throw in a Cactus League game due to right biceps tendinitis.
The 24-year-old transitioned from the starting rotation to the bullpen to help mitigate the injury concerns. He was on a rehab assignment with the team's Arizona Complex League affiliate from May 2-25.
McGraw was moved up on his rehab assignment to the Single-A Inland Empire 66ers on May 26.
Similar to Moore and Alford, McGraw put together a scoreless outing. He fanned one and allowed three hits in two innings of work the same day he was moved up to Single-A on Wednesday.
