10/15/2014 - Arizona Junior Fall Classic
Cal is an athletic and lean junior that showed good projection at the AZ Junior Fall Classic with Baseball Factory. Defensively, he presents his hands in front and is sure with the glove to make plays. He uses his feet to throw and has carry/strength to first. Cal mixed in at first base during the event, and should continue to do so to add versatility for the next level. Offensively, he showed good balance at the dish and was coordinated with his hands & hips to deliver the barrel. He was activated with his hands to launch and has power potential. When Cal can bring his bp swing into games, and learn to trust his pace, he will be a very good hitter. All in all - Kellner is a promising player that has another two seasons to strengthen and trust his ability for next level play.

Cal only showed as a 1B at the event but has really improved his baseball. Foot speed has improved as he ran his best 60 time to date, now a solid 7.38. Hands are clean and moves well laterally. He attacks balls and plays through well with his body. Footwork around the bag is a plus and is a quality receiver. Defensive abilities are now well above average. At the plate, hitting / power grades have improved, now showing as outstanding abilities. Hands are quick, generating bat speed and work through a level swing path. He will put the ball in play and makes consistent contact, mainly to the pull side. Barrel accuracy is a plus with the baseball exploding off the bat when centered.

Cal is a strong, athletic 3B that will graduate in 2016. At the plate is where Kellner shows best, displaying well above average hitting and power numbers through an athletic setup. Hands are quick, generating bat speed to and through a level swing path. He shows a feel and life in his barrel with baseball exploding off the bat when centered, displaying gap to gap power. At 3B, feet are active as he works to square balls up and makes the routine plays. Defensive grade will continue to improve as he presents hands more out front and increases foot quickness. With 3 years to further develop, Cal has the makings of a special type player and will catch the eyes of the collegiate coaches with his baseball abilities.
