11/07/2021 - All-In Membership - Lebanon (Nashville), TN Keller is a tall, lean LHP who will graduate in 2024. On the mound, Keller has a loose/clean arm circle, good balance, and he separates his hands on time. He throws strikes, works well to his balance point, and his off-speed compliment his FB well. More eyes on target and more lower body will help mound effectiveness get even better. At the plate, Keller has an open stance, good balance, and he swings in good rhythm. He loads well, swings aggressively, and he hits hard to the pull side. Added bat speed, letting the ball travel deeper, and more lower 1/2 will help improve offensive numbers.
