The Elite Pitching Instruction and Coaching in Sterling, VA

At The Bullpen, our focus is to develop athletes of all ages and provide the best atmosphere for players to take their ability to the next level. With an abundance of technology and a progressive baseball ideology, we are able to create refined, practical approaches to player development.

Why work with our Pitching Instructors?

Since 2012, we have been giving athletes and pitchers alike the skills they need to succeed in an increasingly competitive environment. Our program provides high-level training multiple times per week, which includes a one-on-one assessment, individualized program design, and supervised training sessions, all in an unparalleled environment.

Head trainer Zach Dials played professionally for five years in the Toronto Blue Jays, Miami Marlins, and Washington Nationals organizations. He was a two-time MiLB All-Star (2006 Short A New York/Penn League and 2008 AA Eastern League) and also played in the prestigious MLB-sponsored Arizona Fall League in 2008. Zach also has his USA Olympic Weightlifting Level 1 Certification, Driveline Baseball Pitch Design Certification, and is an Associate Scout for the St. Louis Cardinals.

Assisted by like-minded associate trainers, Zach will provide athletes with individualized assessments and training to get the most out of each athlete. This program includes year-round strength and conditioning programming to build functionality and fitness in order to increase athletic performance and reduce injury.

The Bullpen blends both advanced physical training methods with some of today’s top technology. Our technology allows us to cultivate mass amounts of data and develop a program for each athlete. These include:
  • Trackman baseball - The most advanced radar tracking system used by all major league and minor league teams and the top D1 baseball programs across the country. This system allows us to capture spine rate, velocity, vertical and horizontal movement, tilt, release height, and many more data points which allow us to assist our player in making immediate adjustments.
  • A state-of-the-art 4D Motion System - The six-sensor system allows us to biomechanically critique the pitching delivery by analyzing angular velocity, angles of the hip and shoulder plane, and if a player has created proper sequencing within the kinetic chain.
  • A HumanTrak Movement Analysis System that combines a 3D camera and internal measurement unit sensors to identify deficiencies in mobility and ROM (range of motion) with various movement patterns, display compression forces on joints, and provides each player with a PDF of all end ranges of motion


  • Pitching mechanics
  • Arm maintenance
  • Strength training
  • Nutrition
We take a serious approach in mirroring college, professional, and other elite programs in an effort to produce top-notch talent. Our advisory board of directors is comprised of numerous baseball professionals who have played, scouted, or are somehow associated with professional athletes; so you can rest assured you're in good hands with our elite team of leaders.


Receiving the highest level of pitching and performance training is just a call away by contacting The Bullpen at (703) 395-0330 today. We look forward to developing your exceptional talent.
