The Arizona Fall League is officially up and running again, with the 2025 season kicking off this week. 
Every year, prospects from all 30 Major League organizations are sent to the desert for extra reps at a level that&#8217;s widely considered a finishing school for players who missed time due to injury or require additional work before the off-season.
For the Toronto Blue Jays, <a href="https://publish.bluejaysnation.com/2025/09/10/josh-kasevich-edward-duran-headline-blue-jays-prospects-2025-arizona-fall-league/" target="_blank" rel="noopener">six of their minor-league players suited up for the Glendale Desert Dogs&#8217;</a> season opener on Tuesday &#8212; including infielders Josh Kasevich and Cutter Coffey, as well as pitchers Alex Amalfi, Kai Peterson, Chay Yeager and Yondrei Rojas.
Kasevich, who&#8217;s Rule 5-eligible ahead of next month&#8217;s draft, enjoyed a strong start to his Desert Dogs tenure, finishing 1-for-2 with a single and a pair of walks &#8212; totalling 17 pitches seen combined between his two free passes. He spent the entire game at shortstop, where he logged 140 innings with triple-A Buffalo during the regular season.
The 24-year-old missed significant time this season due to a stress reaction in his back, which he initially suffered during spring training but reaggravated during the summer.
Coffey, a late addition to the AFL after replacing right-hander Angel Bastardo, also recorded his first hit of the fall with a 1-for-4 performance as the club&#8217;s designated hitter. The 21-year-old is coming off an impressive campaign at high-A Vancouver, where he was named a Northwest League All-Star.

Toronto acquired Coffey &#8212; along with fellow infielder Eddinson Paulino and right-hander Gilberto Batista &#8212; from the Boston Red Sox as part of last season&#8217;s Danny Jansen trade.
While it was an encouraging Day 1 showing on the position-player side, things didn&#8217;t run as smoothly on the pitching side for the organization&#8217;s young hurlers.
Amalfi struggled in his debut, surrendering three runs (all earned) on five hits &#8212; including a solo home run &#8212; and a walk while striking out two over three innings, throwing 46 pitches (32 strikes). Of the 12 batted balls against him, seven were hit hard and featured an exit velocity of at least 95 m.p.h.
Yeager and Rojas were also ineffective for Glendale, allowing a combined four runs on five hits and a pair of walks over two innings of relief, only issuing one strikeout between them.
Peterson, meanwhile, was the lone Blue Jays farmhand to post a scoreless appearance, tossing one no-hit inning with one walk and strikeout each.
The only prospect who didn&#8217;t appear on Opening Day for Glendale was catcher Edward Duran, the franchise&#8217;s top catching prospect. The 21-year-old backstop logged 100 games at the lower minor-league levels in 2025, splitting his season between single-A and high-A.
