@Buckeye 2015 I was surprised as well. Of course, every other (applicable) kid but him has already been throwing pens or catching for a week now, so those players were already known, and that part of the tryout was already complete for everyone but him. So on day 1 of tryouts, they did fielding, throwdowns for catchers, and then hitting.
I reminded Sennason on day 2 that, if they didn't have him pitch/catch that day, to ask at the end of practice if they would mind if he stayed to workout with JV/V and they could watch him pitch/catch. He asked at the end of that practice (when they announced what they said were "first cuts"), and they said just come back tomorrow to practice. When they returned on day 3, they learned that they had all made the team.
So today, he should be catching and pitching, as they said that would be taking place. And I assume that they saw enough in just day 1 and 2 to figure that even if he is a bust on the mound or behind the plate, he'll be usable elsewhere.
