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 for high school and college baseball players.

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 great success with the players we’ve developed.

Here’s some of our updated numbers:

300+ college commits (many were D1 scholarships)

130+ 90mph testimonials from high school pitchers

26 pro contracts to date

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.

Heres some of our statistics from last summers development program…

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).


Hitting Development

Do you want to improve your bat speed, hitting power, and consistency? If so, then we can help you develop into the hitter you’ve always wanted to become.

During your hitting development, you’ll undergo an assessment that’ll look closely at how you swing. You’ll then receive step-by-step hitting instructions in a small group setting from our team of experts.

Our hitters have access to Hittrax technology so they can always see where they stack up. We also provide Live At Bats indoors at our location so seeing live arms happens regularly at OPP.

You’ll quickly discover exactly why OPP hitters like Isaac Wersland stand out from all other baseball players…

Position Player Throwing Development

Most position players need velocity training. Figuring out how to manage that workload in-season and in your off-season is key to maximizing your velocity gain year after year.

We will tailor a throwing program to your needs similar to that of our pitchers. We base our programming decisions off of time of year, throwing mechanics, training history and more.

You can rest easy knowing that we have the proper training and technology you need to maximize your performance (including Stalker Radar Guns and Hittrax for live at bats).

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.

Fast, Flexible & Convenient Scheduling

You’ll be able to schedule your in-person training sessions, quickly and easily, via our handy mobile app. This way you can choose the best times that’ll work around your busy schedule.

Nutritional Guidance & Meal Plans

Thanks to your personalized nutritional guidance, meal plans, and grocery lists, you’ll be able to fuel your performance without any guesswork. And to give your nutrition that extra edge, we’ll also provide you FREE supplements during your training.

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.

College Recruiting & Exclusive Promotion

Lastly, we’ll also offer college recruiting services (optional) as well as exclusive promotion to thousands of colleges and professional coaches who follow us on social media. We’ve already received dozens of D1 scholarship offers through our DMs alone.

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 in 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 the ideal training facility and environment for any baseball player looking to take thier game to the next level. Aj and the OPP team are second to none in looking after your development, tailoring a program to you, and offering a service that is unmatched. After with OPP in house and remotely since 2021, I’ve taken tremendous strides in my game going from D3 school to a D1. None of it would be possible without the help of Aj and his team. As a college athlete who has always been in search for a facility/program that provides the energy, environment, and development like OPP does, I would highly recommend it to any high school, college or pro athlete.”

-Max Smyley, Gardner-Webb 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



  • We’re going to be capping this program at 60 participants and the total cost will be $2,999
  • Slots in the program can be reserved by making a non-refundable $500 deposit by 5/01/24
  • Last summer this program was completely sold out by April 1st, so waiting right up until the deadline to make a call may restrict your ability to gain access
  • 10-weeks in length starting 6/03/23 and concluding 8/12/23
  • If you want to start earlier or later (depending on your release from school) and join our summer development for the same length in time, that is no issue. Just let us know during your consult and we will take care of that.
  • For athletes who would like to stay longer than 10 weeks in length, we will pro-rate your stay for the remainder time you would like to stay. Our schedule is fluid and can change based on your needs.
  • The remaining balance of $2499 will be due for all participants on or before your start date.

Due to the significant volume of incoming athletes each summer, OPP is not in a position to facilitate the housing search and logistics process, so athletes are expected to handle this task. I can’t say for sure what each athlete’s lifestyle habits look like, so it is tough to project exact cost of food, but I would be comfortable predicting that you can find housing in our area for somewhere between $400-$1,000/month, depending on how many people the athlete is willing to live with and how nice the athlete would like it to be.

We will respond via email within 24 hours of your registration deposit!
