How about a personalized baseball bat engraved with the couple's names and wedding date? You could also consider gifting them tickets to a baseball game or a baseball-themed piece of artwork for their home. Another idea could be a set of baseball-themed glasses or mugs that they can use for entertaining guests.
Or you can get her/him a star map with the date of the wedding.
