My son pitched and caught thru high school, but was always watched very carefully to be sure he didn't over do it. He went to college as a catcher but at his D1 they always looked at any of the players who had experience pitching in the fall to see what they had. He went to a D1 JUCO his freshman year and was a catcher only. He was picked up his soph year by a good mid major D1 and won the starting catchers job as a soph, but broke his hand sliding into second the first inning of the second game of the year. In a cast all he could do was throw, and when he was released after 6 weeks he wasn't allowed to hit or catch. He entered a few games and pitched, did well some games, struggled in others. Next fall at pro day he hit 95 twice in front of the scouts. Spent that year as DH and did a little pitching. He was drafted as a pitcher, didn't sign and returned to get his degree. His senior year he was all conference catcher. He played 4 years after college, the first as a pitcher and the next three as a catcher.
