Jack Laubacher – Oklahoma State 🤠

Met Jack back in 8th grade and have watched him develop into a legit arm. We’ve focused heavily on building strength and explosiveness throughout his development.

After battling back from Tommy John surgery, Jack’s resilience, attention to detail, and meticulous work have set him up for a bright future as he heads into his first year at Oklahoma State.

A lot of athletes don’t have a work ethic problem.

They have a plan problem.

No real routine in the gym.
No structured arm care.
No throwing progression.
No mobility or recovery plan.

At Costello Coaching, we take the guesswork out of development and give athletes a structured plan to follow every day.
