It's rec, you should be moving players around like others have said. The last year I coached baseball, we had a kid who was a great catcher. The year before, his coach had him catching almost the entire time, except when he was pitching. He enjoyed catching but wanted to play other positions. We only had one other catcher, and he wasn't nearly as good but he loved it and would have been happy to catch every inning. We did about a 50-50 split.
