Arizona Fall League Overview

The Arizona Fall League (AFL) serves as a platform where Major League Baseball teams send their top prospects. Each organization usually dispatches seven players to participate in this competitive league, which runs from October to mid-November. The AFL includes a regular season, playoffs, and events like the annual Home Run Derby and the Fall Stars Game.

Notably, a significant percentage of players who participated in the AFL have gone on to achieve success in Major League Baseball. Approximately 41% of the players selected for the 2025 MLB All-Star Game had AFL experience, illustrating the league’s role in developing future stars.

Fan Vote for Final Roster Spot

Pagliarini is currently competing against Joshua Kuroda-Grauer from the Athletics and Braden Montgomery from the White Sox in the fan vote for the final American League roster spot. The outcome will be a reflection of fan engagement and the prospects’ performances this season.

The excitement surrounding the Arizona Fall League highlights the Seattle Mariners’ commitment to developing young talent, as Farmelo and Kingsbury prepare to showcase their skills on a larger stage.
