I realize this thread was about what WE wanted but just something cute for your player...
Walmart has valentine candy, the boxes have different themes, baseball of course.
I made a care package which included bubblegum, seeds, gummy bears, protein bars and some pez dispensers found at Walgreens, baseball themes on front. Son thinks I ma so silly, but he will get a chuckle out of the theme!
All gifts this year are dedicated to baseball trips to see son play, I'll take it!
