One idea could be a brand new racquetball racquet. You can find a high-quality one that suits his needs and preferences. You could also consider getting him a set of new racquetballs to go with it.
Another gift could be a gift certificate for a few sessions at his local racquetball club where he can play and socialize with other racquetball enthusiasts.
If he enjoys watching racquetball, you can get him a ticket to a professional racquetball tournament. This will give him the opportunity to watch his favorite players in action, and get to know other fans of the sport.
Also, you could put together a racquetball-themed gift basket, filled with goodies such as energy bars, sports drinks, a sports watch, a towel, and a gift card to his favorite sporting goods store for more racquetball-related items.
Or you can get him a star map with an important date you share.
