01/15/2016 - Under Armour All-America Pre-Season Tournament
Obrien is a young two way player out of Wisconsin's 2018 class. Defensively, at 3B, he controls his body well, uses proper footwork and has a clean exchange to throw. Has a good loose, athletic body that carries onto the mound. A repeatable delivery with clean controlled technique allow him to be efficient as a RHP. His fastball topped at 77 mph and he mixed speeds well with his CB. Given that he has three HS seasons left, he should develop into a nice two way player but projects really well as a CIF. At the plate, Sean is advanced for a 2018 player with a good athletic setup, quiet load that allows him to create leverage and shows the ability to drive the baseball into the gaps.

12/27/2014 - Baseball Factory Christmas Camp & Tournament at Pirate City - Session 2
Sean is a very promising 3B/RHP that has a very effective, deceptive delivery. He topped out at 75 with his fastball, spun an 11/5 CB, and showed feel for a CH with arm side run. He is very controlled with his mechanics and fires a quick arm to delivery with fluidity. Becoming more consistent from the stretch and staying directional will improve control and command. Defensively, he made plays with ready hands in front and was soft with the glove to secure the ball. He worked to consistently stay low to field and use his legs to throw. Adding agility work to speed up his feet and arm strength will increase play ability. In the box, he displayed fluidity to hit with a controlled load and direct path to ball. He is a contact type hitter that stays in the middle of the field and with more reps will enhance feel to hit. In all - Sean is a standout freshman that has a lot of potential and projection at either position in the future.
