In a lot of instances, a quality pitcher is also a top-shelf hitter just because of the athleticsm factor. If he can do both, he's playing somewhere in every game.
When i was a sportswriter in the 90s I went to a tournament when Josh Beckett was a senior at Spring. In the first game he pitched a 17-strikeout no-hitter. In the second game he hit 2 solo home runs, and threw a guy out at home from the track on an attempted sac fly.
If your kid likes them both, lean into it.
WARNING: I have a deep-seated desire for others to love the Star Wars franchise as much as I do, in exactly the way I do, and get snippy and sensitive and passive-aggressive when they don't.
