Do you have what it takes to land that highly coveted D1 baseball scholarship or to eventually hear your name called in the MLB Draft?

Bottomline: if you haven’t improved your baseball skills significantly over the past year, then you’re not receiving the right training.

The good news is, we can help you not only target your biggest weaknesses and strengths, but we can help you greatly improve on ALL of them. This will increase your chances of landing that dream D1 baseball scholarship or eventually get your called in the draft.

Your journey begins with our exclusive in-person training program here at our private training facility in beautiful Phoenix, Arizona…

Introducing Our Complete ‘One Stop Shop’ In-House Training Program That Offers You Everything You Need to Succeed

This is our most exclusive player development program. It’s offered in-person on a monthly membership basis here at our Phoenix, AZ training facility.


We train high school baseball players (14+) who want to land D1 scholarships or eventually get drafted into MLB. But we also help current collegiate-level and professional players who want to maximize their skills and talents as well.

“Since our opening in 2018, we’ve had nothing but big success with
the players we’ve developed. We’ve had over 300+ college commits
(many were D1 scholarships), 130+ 90mph testimonials from high school pitchers, and 25 pro contracts.”

Our training system will provide you with the proper guidance, detailed feedback,
in-depth training (and more) you need from our dedicated team of expert coaches and trainers.

Many of our new athletes are already boosting their averages thanks to our training. Here’s some of the recent statistics in a 3.5 month time period…

Our In-House Program Covers All aspects of your Pitching Development

Pitching Development

It’s no secret, in todays game velocity gets you in the door. It’s hard to get your opportunity at the next level with a baseline velocity that can play at that level. If you’re a pitcher who wants to increase your velocity or maybe just improve your current aresenal, then we can help you.

During your development process, you’ll undergo a detailed assessment that’ll look closely at your mechanics. You’ll then receive a fully tailored throwing program that’ll help you achieve your biggest goals as a pitcher.

Most pitchers need velocity training. Others may require training that’s focused on pitch design, or live competition against our own hitters.

Either way, you can rest easy knowing that we have the proper training and technology you need to maximize your performance (including Rapsodo, Stalker Radar Guns, and Hittrax for Live AB’s).

Here’s a Full Breakdown of What You’ll Receive During Your In-House Training

Tailored Training Programs

All programs will be 100% tailored specifically to your unique needs and goals as a baseball player. After working with over 2,000 baseball players to date, we have the data points and experience to know what works best. These programs will cover all aspects of your baseball development - including throwing, strength training, and mobility.

Detailed Assessments & Mechanical Analysis

We’ll conduct detailed assessments and a full mechanical analysis to determine where and how you need to maximize your throwing ability. We then walk you through your strengths and weaknesses and lay out a detailed plan on how to improve. This will allow you to not only know the why behind your training, but also improve your education of the throw so you can make adjustments yourself as you train.

Hands-On Expert Coaching & Training

Our experienced coaches will provide you with on-going support, specific feedback, and step-by-step guidance throughout your training. We’ll also track your forward progress and regularly check-in with you to keep you focused.

Advanced Technology Tools & LIVE Setups

You’ll be able to compete against others in a LIVE setting with our complete set up. Get access to full-length cages, mounds, stalkers, Rapsodo, Hittrax, Live AB, and more.

Leadership, Mentorship & Mindset Training

We go beyond just the physical aspects of training. Our mentorship will help you develop a winning mindset and effective leadership skills that’ll build your character. Our coaches have all been there and had to go through similar situations you have had on the field. We failed so you don't have to. You will get access to years of experience and coaches who have worked with thousands of baseball players.

Private Recovery Room Access & Therapy

Along with your training, you’ll also receive Red Light Therapy, MarcPro Recovery Units, body tempering massages, cupping, and more inside our private recovery room. This way you can rapidly speed up your recovery time after every training session.

Our Players Are Getting Real Results Thanks To This Hands-On Training

“Training with OPP has allowed me to play at the collegiate level. Going from a junior topping 81 mph to a senior hitting 90 mph. Aj has provided me the framework to get me where I am now. Throughout my 3 years with OPP, I have continuously made strides both on the weight room and on the field. I couldn’t be happier with my decision to train with OPP”

-Damian Tillie, Franklin College

“OPP is without a doubt the best training experience I have ever been apart of. I have done both the remote training and in-person in Arizona. In one summer of in person work my strength, power and throwing velocity all improved astronomically thanks to the culture that has been founded at OPP. When you’re surrounded everyday by dudes who wan tot challenge you and watch you succeed, you are guaranteed results. OPP has changed the entire trajectory of my baseball career and I will be forever grateful that I chose to work with them”

-Cade Fletcher, Carolina University

“When I first started remote training with OPP, I was fresh off getting released from a short 10 day stint in the frontier league. I was sitting 90-92 at the time. After following the programming, all of the hard work in the weight room translated to the field. This last season, I sat 93-96 touching 97. I’m still consistently seeing results. Can’t wait to see what this season has in store. Wouldn’t be where I am today without the help of OPP”

-Matt Dallas, New Jersey Jackals In The Canadian American Association Of Professional Baseball League
