Frimmer is an athletic, fleet-footed, and skilled prospect who plays with a physical edge. That list of assets makes Frimmer an ideal two-way midfielder. Frimmer excels at vacuuming up groundballs in the defensive end or on a faceoff, then turning upfield to push the rock for a transition opportunity. Once he gets below the restraining line, Frimmer is a legitimate threat to crank a shot into the net on the dead sprint. In settled action, Frimmer is a master at coming off screens and then ripping a shot. He can dodge going to his left or right and shoot/finish with either hand, so Frimmer is extremely difficult to defend 1v1. Additionally, Frimmer can carry the ball to X and initiate or feed from there. When he dodges from X and then turns the corner, Frimmer can execute filthy inside rolls to create scoring chances around the crease. Defensively, Frimmer is a gritty short stick who will not hesitate to play the body or deliver a devastating crowbar.
