Positions

I competed at the college level as a pitcher and outfielder — first at Dawson Community College (JUCO), where I developed my skillset and earned my shot at the next level, then at Northern State University, a Division II program. My experience navigating the recruiting process, competing at two levels of college baseball, and the daily grind of being a college athlete shaped everything Bullpen Athletics is built on.

No facility. No fluff. Just a former college pitcher who has been through the process and is genuinely invested in helping your athlete get there.

I started Bullpen Athletics because I care deeply about helping athletes develop the right way and getting the opportunity to play at the next level — like I did. I've been the athlete trying to figure things out, grinding to improve, dealing with setbacks, and learning what actually translates onto the field. I continue to learn and study the game as I make my own athletic comeback, and the lessons I've gained about training and performance after college are ones I wish I had earlier. I want to pass every one of those lessons on to as many players as possible.

That's why Bullpen Athletics operates as a mobile pitching development service — we come to you. No fancy facility required. What matters is the coaching, the reps, and the results. We bring the expertise and the plan; you bring the work ethic.

What We're Built On
The foundation behind every session
⚙️
Hard Work

No shortcuts. Every rep is an opportunity. We bring the effort every single session and expect the same from our athletes.

🔍
Attention to Detail

Small mechanical adjustments create big results over time. We focus on the details that coaches at the next level notice.

🧠
Athlete Development

We develop the whole athlete — on the field and off. Confidence, discipline, and the right mindset matter as much as mechanics.

📈
Continuous Learning

Rylan continues to study and train alongside his athletes. The best coaches never stop learning — and neither do we.

📍
Mobile Development

We come to you. No facility required — we bring elite pitching development to your field, park, or mound. Your schedule, your location.

Coaching Philosophy
The Approach
01
Quality Reps Over Everything

Mindless reps build bad habits. Every rep at Bullpen Athletics has a purpose, a focus, and immediate feedback attached to it.

02
Individualized Coaching

Every athlete moves differently. We don't force one style on everyone — we build around each player's mechanics and help them move more efficiently.

03
Teach Athletes to Understand Their Movement

When athletes understand why a change works, they own it. We coach with intent so players can self-correct and keep improving between sessions.

04
Transfer to the Game

Cage work and field work only matter if it shows up in games. Everything we do in training is built to translate directly into real game performance.
