Arizona - This season we are excited to roll out our feature highlighting the State's Top Fastball Velocities with the Prep Baseball Heat Sheet. This list is made using only the players our staff has seen in person and we will be updating the Prep Baseball Heat Sheet weekly with players running it up to 87+ mph. Keep an eye on this list to see who earns their spot and ultimately who has the top fastball in the state during the 2026 High School Season!

Please note that this list includes only players our staff has evaluated in person, with all velocities verified firsthand via Stalker.
