Mariners' best prospect story has nothing to do with Kade Anderson or Lazaro Montes

As has been the case throughout the Jerry Dipoto era in Seattle, the Mariners farm system is once again producing tremendous results at the various levels of the minors. Highlights have included the phenomenal success of Kade Anderson and Lazaro Montes, but in truth this could have been expected. For us, the number one prospect story of 2026 has been the rise of Jonny Farmelo.

It's not that Farmelo's talent was ever in doubt, with the Mariners selecting him 29th overall in the 2023 MLB draft. At one time described as a budding five-tool talent, he still has that intriguing mix of size, strength and athleticism. Rather, the doubt was whether he could stay healthy, with two lengthy spells on the Injured List limiting him to 75 combined games during his first two pro seasons with the the M's organization.

MLB Pipeline still thought enough of Farmelo to place him No. 78 overall in their preseason top 100 prospect rankings. The pressure was on though, not helped by Colt Emerson's expedited rise through the minor league system. Fair or not, it was only natural for Mariners fans to continually compare the two young prospects, given that Emerson was selected just seven picks ahead of Farmelo.

The way Farmelo's 2026 season started in High-A Everett though, the gap might as well have been seven rounds. April proved to be a rough one for him, batting just .200 with a 26.7 percent strikeout rate and .731 OPS which alluded to a swing-and-miss mentality. It wasn't all bad, highlighted by an encouraging 17.1 percent walk-rate, but a 92 wRC+ had his arrow pointing down, with plenty still to prove.

A season which started with a whimper for Jonny Farmelo has now turned into a rousing success

Fortunately for the Mariners, May proved to be a better one for Farmelo as he batted .273 and continued to manufacture free passes at a 16.0 BB%, resulting in a .779 OPS. The strikeout rate was still too high at 26.1 percent, but a 110 wRC+ outlined his improvement and MLB Pipeline moved him up to No. 71 in their prospect rankings.

However, even this didn't prepare anyone for what came in June.

Quite simply, Farmelo was electric during this past month, which included an outstanding .309./.412/.629 slash line, 1.041 OPS and 164 wRC+. Highlights included a seven-game hitting streak and blasting seven home runs. The seven bombs in just one month was significant for passing his previous season high, and to cap it all he ended June with a walk-off:

What's been key to all this success is Farmelo's ability to remain injury-free, with him playing in 71 games and looking as healthy as at any time since being drafted. MLB Pipeline is clearly impressed with everything he's been doing, with him being moved up again in their latest prospect rankings, this time to No. 64.

It will be interesting to see what the future holds for Farmelo, who's only with the Mariners because they were awarded an extra draft pick after Julio Rodríguez was named 2022 Rookie of the Year. However, the hope is the speedy outfielder continues to trend in the right direction and add to his standing as the best prospect story in the organization this season.
