Brett Thorney
State Scouting Director

With the current cancellation of spring baseball season, we want to take the time to highlight some players from our past events. Here's a look at the Pitchers that took the hill from the Preseason All-State Games that took place on January 26th at Arizona State University. There were some excellent pitchers in attendance, highlighted by MLB draft hopeful & Arizona State commit, Ronan Kopp of Scottsdale Christian. There was talent on the mound across all of the different graduate classes in attendance thatscouts should keep an eye on going into the summer season. Here are reports from the afternoon, listed in alphabetical order. 

Stay tuned the rest of the week as we will be highlighting some of the top prospects from the event.
