12/27/2013 - Baseball Factory Christmas Camp & Tournament at Pirate City Mueller is a hardworking player with a positive attitude and plus makeup and continues to show in the OF where he displays smooth / clean actions. Feet are quick / athletic as he takes proper routes / angles in tracking down balls and maintains solid body control. He reads balls well off the bat and covers a lot of ground, displaying range. Defensive grade will continue to improve as he works to get behind balls more to play through with momentum to target. Throws are accurate, but will benefit by building more arm strength through a long toss program and work on getting rid of the baseball more quickly. At the plate, he shows a squared, athletic stance with balance. Hands are quick and work through a level swing path. He makes consistent contact through a solid line drive approach, mainly to the pull side. Hitting grades will continue to improve as he learns to keep hands inside the ball to utilize all fields. Power grades will improve as he learns to use his lower half more.
