Hear directly from Justin on how Underdog MIF Academy helps undersized middle infielders get recruited to play MIF for a college baseball team.
Justin Fields
Mentor / Coach
Founder
Hey, I'm Justin Fields.
And if you're an undersized middle infielder who's willing to outwork everyone but still isn't seeing the results you want, then my story will probably sound a lot like yours.
I wasn't the biggest, strongest, or most physically gifted player growing up. As a sophomore in high school, I weighed just 125 pounds, struggled to hit for power, and topped out at an exit velocity of 75 mph. Putting on muscle didn't come naturally, and I wasn't the player that college coaches were lining up to recruit.
But my biggest challenge wasn't a lack of work ethic.
It was a lack of direction.
I finally figured out what I wish someone had taught me years earlier.
I learned that becoming a great middle infielder isn't just about lifting more weight or taking more swings. It's about following the right plan, developing physically and mentally, and understanding how every piece of your training fits together.
That's why I created Underdog MIF Academy.
My Mission
To give undersized middle infielders the blueprint I never had.
My goal is to help undersized MIFs stop guessing, train with purpose, build confidence, and maximize their potential through personalized coaching, accountability, and mentorship—so they can become the best middle infielder they're capable of being.
Underdog MIF Academy exists to build next-generation middle infielders—mentally and physically. My mentorship bridges the gap of the daily grind and real results.
