He had just turned five and was allowed to play up with the "older kids" in the t-ball league...
In his first game - he caught a fly ball at SS and threw it to 1st base to double up the runner who (of course) didn't know to tag up. Nobody told him - just knew to do it. Later in the same game he made a diving stop and made the throw from his knees from SS to 1B for the out.
