About Me

My name is Mason Jablonski, I am 17 years old and in the class of 2022 at Ensworth High School in Nashville, Tennessee. I have been playing sports my entire life, but at an early age baseball became my favorite and the one I focused on the most. I love all the aspects of the game and the life lessons baseball has provided me. Throughout my life, baseball has continued to teach me the importance of hard work, preparation, and resilience. In many ways, baseball is a game of dealing with failure, and I pride myself by responding to failure with not only a good sense of humor but also a desire to work harder. I come from a family that has always placed a high value on educational achievement. All I want is an opportunity to continue to play baseball at the next level while getting an education.

Right handed hitter, shifts to his backside to start his swing and tends to stay on his backide, upper body swing with an uphill swing plane, stays short to the ball but doesn’t use his strong lower half much to generate bat speed, puts the ball in the air consistently. 7.25 runner, young fundamentals in the outfield on defense, long arm action with some developing arm strength when he gets the ball down and on line. Good student.
