|Mathisen is the best high school catching prospect in the draft, though he hasn't seen much time behind the plate for Calallen High, which has deemed him more valuable as a shortstop and pitcher. There's no question his pro future is as a backstop, and he has the tools and desire to make it there. He has plus arm strength and the athleticism to become a good receiver, though his inexperience shows as he flinches at times when catching the ball. His makeup is off the charts, as he has the leadership ability to run a pitching staff and the work ethic to succeed. The 6-foot-2, 215-pound Mathisen has the swing and strength to hit for average and power from the right side of the plate. He's a good runner for a catcher, grading as close to average, though he'll probably lose a step once he starts catching every day. Like crosstown Corpus Christi rival Courtney Hawkins, he's a Texas recruit.
