Julio Rodríguez's gift to Mariners is 1 of 7 reasons to watch Arizona Fall League

Most Seattle Mariners fans are understandably focused on the present, as their beloved team takes aim at the playoffs, a division title and potentially even more. However, as with most organizations, the M's always also have an eye on the future.

As per MLB.com, rosters were officially announced last week for the six Arizona Fall League teams, with the season taking place between Oct. 6 and Nov. 15. The rosters include seven prospects from the Mariners, who will play for the Peoria Javelinas:

Jonny Farmelo, OF (SEA No. 7/MLB No. 79); Marcelo Perez, RHP (No. 19); Brock Rodden, 2B (No. 22); Tyler Cleveland, RHP (No. 30); Christian Little, RHP; Brock Moore, RHP; Stefan Raeth, RHP

The headliner for the Mariners is undoubtedly Farmelo, who is one of 13 top 100 prospects who will play for the Javelinas. As SoDo Mojo's Tremayne Person previously wrote, he was the result of the M's receiving an extra 2023 first round draft pick thanks to Julio Rodríguez being named 2022 AL Rookie of the Year.

Injury-impacted seasons for Jonny Famelo and Brock Rodden

Farmelo quickly set about showing the Mariners they were wise to select him with the 29th overall pick, as he batted .264 with a .820 OPS during his debut season in 2024 with Single-A Modesto. However, his campaign was ended after just 46 games due to a torn right ACL.

The 21-year-old has continued to battle injuries this season after missing time with a stress fracture in his ribs. As a result, he has been limited to 29 games during the 2025 campaign with High-A Everett, so the chance to get additional playing time in Arizona should prove to be invaluable.

This also applies to Rodden, who saw his season with Double-A Arkansas ended due to breaking the hamate bone in his wrist and had injury issues in general. Selected in the fifth round of the same draft as Farmelo, the 25-year-old had been tremendous when he was on the field, as evidenced by batting .295 with a .822 OPS in 37 games for the Travelers.

Mariners pitching prospects will have some inside help

Mariners pitching coordinator Quinn Cleary has been picked as the Javelinas’ pitching coach, with a familiar face potentially proving helpful for the likes of Perez and Cleveland. Perez might be the higher rated prospect, but he struggled this season in Double-A Arkansas, while Cleveland prospered with a 0.89 ERA and 0.934 WHIP in 20.1 combined innings for the Travelers. He did not give up a home run all year.

Of the other three pitchers, Little stands out most, with Person writing last month about how he appears to be on a trajectory similar to a certain Bryan Woo. The 22-year-old has an array of pitches highlighted by a fastball which can reach 99 mph. If he turns out to be even half as good as Woo, then the Mariners will have done well.

Moore will need to take advantage of this opportunity after his own challenges with injuries this year, combined with just not looking good at all when he did pitch. As for Raeth, he was tremendous in High-A Everett, but encountered some struggles after being promoted to Double-A Arkansas.
