05/28/2019 - 2019 Under Armour Showcase: Baseball Factory's National South Kellum is a tall and athletic 2020 1B prospect. At 1B, Kellum works off the bag well, has good footwork to the ball, and makes accurate throws on double plays. He presents a low/early glove, plays through the ball, and makes the routine play. At the plate, Kellum starts in a squared stance, loads his hands back into the drive position, and gets his backside through the ball. He has a middle approach and drives the ball to all fields. Kellum has tremendous upside and we hope to see his progress in the future.
