Catching up with the Mariners' first 5 picks from their 2025 draft class

Last year, the Mariners had one of the most impressive draft classes of any MLB organization. It was another year of Seattle adding some excellent amateur talent to their professional ranks and it's especially important given how often the organization biases towards depending on homegrown talent to lead the team.

The team's first five picks are already putting up excellent numbers for the most part and suggest that the club has a bright future ahead.

How the first 5 picks of the Mariners' 2025 draft class have performed so far

LHP Kade Anderson (3rd overall pick, No. 2 SEA prospect)

Anderson has dominated prospect headlines for the Mariners thanks to his outstanding numbers in Double-A. Across 38.2 innings, he has a 1.63 ERA, 2.00 FIP, and a 40.8% strikeout rate. If it weren't for an excess of starting pitching depth, his performance may have already resulted in him being called up.

A few weeks ago, Jerry Dipoto mentioned that the organization was still waiting for him to overcome his first real obstacle, which came in the form of a start in which he gave up five earned runs in just four innings. However, he struck out seven batters in 4.2 scoreless innings in his very next start. This could be enough for at least a promotion to Triple-A, but the Mariners have remained frustratingly quiet about that possibility.

C Luke Stevenson (35th overall pick, No. 8 SEA prospect)

Stevenson was already generating prospect hype at the end of last year and with a solid chunk of games with High-A Everett under his belt, it seems like the bullish sentiment was well-deserved. Across 150 plate appearances, he has hit to a 142 wRC+ with an impressive 23.3% walk rate. His power, which graded out as one of his better tools, has resulted in a respectable .455 slugging percentage but with just three home runs so far, it's possible that his biggest hits are yet to come.

SS Nick Becker (57th overall pick, No. 9 SEA prospect)

Although he played in six games with Single-A Modesto after being drafted last year, Becker has spent all of his 2026 season in the Arizona Complex League. It's not too concerning since he's still just 19 years old and he has been hitting well against his peers, posting a 117 wRC+ over 63 plate appearances with a 20.6% walk rate and 12 stolen bases.

With Colt Emerson doing an excellent job of living up to his lofty expectations in his rookie year, the Mariners aren't exactly clamoring for more help at shortstop, but having more prospects at the position could still drive a future trade.

RHP Griffin Hugus (91st overall pick, No. 11 SEA prospect)

Hugus was the first member of the 2025 draft class to hit a major snag in his development. He sustained an injury during spring training and required Tommy John surgery, delaying his professional debut for the foreseeable future.

Heading into the season, he was touted as a prospect with immense upside, but the Mariners will have to wait more than a year to try and cash in on his potential.

LHP Mason Peters (122nd overall pick, No. 15 SEA prospect)

Like Kade Anderson, Peters has been pitching to elite numbers albeit against much lower competition. With Single-A Modesto, he has posted a 1.74 ERA and a 3.19 FIP over 31 innings.

What's even more impressive is that he also has a 37.5% strikeout rate while walking just 5.8% of batters. After a few more strong starts, it wouldn't be surprising to see him promoted to High-A Everett to continue his development.
