01/15/2016 - Under Armour All-America Pre-Season Tournament Arrieta is a strong/projectable power hitting 1B. At the plate, this righty takes an aggressive hack with bat speed to and through the zone. He barrels the ball up as it explodes off of his bat when centered. He hits the ball where it's pitched with the ability to spray it to all fields. At 1B, he shows his athleticism with his quick footwork around the bag. He has soft hands and can go get it and pick it. Jonathon will be a run producer with his game changing power and will play at a very high level.
