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.
