Jonny Farmelo has long tantalized scouts with his dynamic toolset -- when he's been able to stay on the field. Finally healthy over a sustained period for the first time in pro ball, he's fulfilling the potential that made him the 29th overall pick in the 2023 Draft. MLB's No.

June 28, 2026

On Friday night, left-hander Kade Anderson, the Mariners' No. 2 prospect, struck out nine batters in his start for Double-A Arkansas. Right-hander Ryan Sloan must have viewed that as a challenge to him.

June 27, 2026

When Felnin Celesten joined the Mariners organization at the start of the 2023 international signing period, he was touted as potentially the highest upside shortstop on the market in a decade. Seen as a potential five-tool player as he fills out, the hype has continued to grow. The only thing

June 20, 2026

June 14, 2026

Lazaro Montes joined elite company with one swing Sunday. MLB's No. 27 prospect clubbed his 20th home run of the season in Double-A Arkansas' 12-7 victory over rival Northwest Arkansas at Dickey-Stephens Park.

Rain, rain, go away -- unless it sets up for a top prospect doubleheader day. Inclement weather rolled through North Little Rock, Ark., on Friday. While postponements can often lead to logistical issues, this one resulted in a special double feature at Dickey-Stephens Park on Saturday. Kade Anderson and Ryan

June 12, 2026

Jonny Farmelo and Felnin Celesten as a duo are as dialed in as any hitters in June. Ranked just one spot apart among the top prospects in the Mariners' system, Farmelo -- No. 6 -- and Celesten -- No. 7 -- took inspiration from one another and homered in the

June 10, 2026

By most measures, the season is still young. Some alternate identities have yet to be donned, All-Star Futures Game rosters have yet to be announced and there's a whole second half of the Minors campaign. Even with so much left in the balance, it might already be time to ask:
