Formerly known as the AZ Baseball Ranch, the Arizona Pitching Arsenal™ is an elite pitching training and development company led by MLB Throwing Coordinator Ken Knutson. We work with pitchers ages 12-25+ at the Papago Baseball Complex in Phoenix, AZ.


During Ken Knutson’s 30 years of Division I coaching experience, he has produced 33 All-Americans, U.S. National Team players, Olympic athletes, several first round draft picks, and more than 60 MLB drafted pitchers, including two-time Cy Young Award winner Tim Lincecum.

Knutson served as University of Washington head coach from 1993-2009 and Arizona State University pitching coach from 2010-2014.  He concluded his UW career with the most wins in program history and 15th most in Pac-10 history. He coached 16 all-conference pitchers at ASU and at least one every year at UW.

Upon retiring from 30+ years of coaching NCAA Division 1 College Baseball, Coach Knutson formed the Arizona Pitching Arsenal™ to continue his passion for developing pitchers. Through the Arsenal, Ken has been able to impact pitchers around the world from youth to professional baseball. It is Ken’s mission to develop elite pitchers and help them take their game to the next level. This is accomplished through his Complete Pitching Approach which encompasses the physical, mechanical, and mental aspects of the game.

In 2015, Ken Knutson signed with the Cleveland Indians baseball team to coach throwing development.


For every Pitching Arsenal™ program, we bring together a very select group of talented and knowledgeable coaches to provide personalized instruction and hands-on training. We are highly selective when choosing our coaches; ensuring that our coaches understand the Arsenal method to individualized training.

Attendees have the opportunity to be mentored by our college and professional players that have gone through the program and training and can share their personal stories and advice.

Specific coaches for each program will vary, but our world-class instruction will not!

All of our coaches are highly qualified to teach you to pitch the Arsenal Way!
