Here is each club’s Arizona Fall League sleeper prospect

MLB Pipeline has highlighted sleeper prospects heading to the Arizona Fall League from across Major League organizations. The selected players sit outside their organizations' Top 30 Prospects rankings, using the fall slate to demonstrate their ability against high-level competition.

Key names highlighted include Blue Jays catcher Aaron Parker, who hit 19 home runs for Double-A New Hampshire, and 29-year-old Braves reliever Tyler LaPorte, who posted a 1.84 ERA in Double-A. The league season opens on Saturday with the Glendale Desert Dogs hosting the Salt River Rafters.
