+ C Jack Mazur (Hartford, 2027) has some upside and is a player who impressed with the bat on Sunday. Mazur showcased an aggressive yet controlled move to the hitting zone and hit with a very well sequenced swing from the right side of the plate. The exit velocities will continue to tick up as Mazur adds more strength to his frame. He was hitting hard line drives consistently through the back of the facility and was repeating his right handed swing consistently throughout his round. His displayed soft hands and solid blocking technique during defense as well. Mazur will be a name to monitor going forward for our staff.
