Human Performance Scientist & Strength Coach

Building the Engine Behind Every Pitch

Dr. John Adamek is a human performance scientist and strength coach with over 15 years of experience developing athletes across Division I, Olympic, and professional levels. His career bridges evidence-based training and research with applied sport science, integrating biomechanics, neuromuscular assessment, and cognitive performance into athlete development systems.

He holds a Ph.D. in Biobehavioral Kinesiology from the University of Illinois, along with a B.S. and M.S. in Sports Science from the United States Sports University. His research centers on the intersection of exercise, cognition, and psychological factors, with multiple publications and conference presentations. He has collaborated with USA Baseball on integrating objective data-capture devices (e.g., Optojump) into their sports science testing and evaluation protocols for the MLB Prospect Development Pipeline, and has interpreted and provided player evaluations for major organizations including the NFL, NHL, NBA, USTA, and USOC. He has also worked with Continuum and currently holds a role at Bristol Myers Squibb.

John's role within Locked'n Pitching is crucial to helping our pitchers and athletes grow healthier and stronger than before, using science-based research as the foundation for every program.

Division I Catcher

From Behind the Plate to Behind the Scenes

Alex Gomez is a catcher who has played at every level of competitive baseball, from a decorated four-year career at Rutherford High School to Division I baseball at Old Dominion University and William Paterson University. A Rutherford, NJ native and brother of fellow Locked In Pitching coach Jacob Gomez, Alex brings a catcher's eye for detail to everything he coaches.

Along the way, Alex has battled through his share of injuries — and rather than letting that slow him down, he's turned the recovery process itself into one of his greatest tools, helping the athletes he works with come back stronger, smarter, and more prepared than before. Still chasing his own dream in the game, he's learned to recognize that same fight in every athlete who walks through the door, and meets them there.

Professional Pitcher

Turning Experience Into Understanding

Breyln Jones is a professional pitcher who brings firsthand experience from affiliated and independent professional baseball to every athlete he coaches. A Rutherford, NJ native, Breyln was drafted by the Los Angeles Dodgers before continuing his professional career through the Frontier League and beyond.

He believes real development happens when an athlete works it out for himself rather than being handed the answer. Instead of just telling a pitcher what to fix, Breyln works alongside him — asking the right questions and guiding the process — so the athlete builds the awareness to recognize and correct it on his own.

Professional Pitcher

Building the Athlete Before the Pitcher

Durbin Feltman is a longtime professional pitcher with extensive Triple-A experience. A TCU All-American and Boston Red Sox 3rd-round draft pick, he has thrown as hard as 100 mph and has learned from a wide range of coaches, pitching coordinators, strength staffs, and player-development systems throughout his career.

Durbin's coaching philosophy centers on developing the athlete first, then building a strong, repeatable throw before ever worrying about pitches. He believes in establishing a foundation of athleticism, movement, and strength before layering in pitch design, command, and sequencing — and wants every athlete to understand not just what they're doing, but why, so they can take ownership of their own development and keep improving on their own.

Professional Pitcher

Mechanics Built for Effortless Velocity

John Kelly is a professional right-handed pitcher who pitched collegiately at Oklahoma State University after starring at Rutherford High School. He most recently played with the 2025 Miles Wolf Cup Champions, Kane County Cougars.

John's strong suit is his understanding of mechanics to maximize arm health and effortless velocity. He's also an ISSA-certified Personal Trainer with qualifications in strength and conditioning, bodybuilding, and nutrition. He coaches because he genuinely enjoys it — working with kids who have the drive to learn and progress, just like he did chasing the same dream of playing professional baseball.
