Nine-year-old Brady Kahle is making a big league effort to help a baseball buddy with brain cancer. After learning that his friend Landen Palatino was diagnosed with the disease in early January, the Springfield, Massachusetts, little leaguer decided to sell off his valuable baseball collection to raise money for Landen’s family. After selling cards at two shows, Brady estimated he sold around 500 cards, netting over $7,000. Now card companies are getting in on the effort. Collectibles giant Upper Deck sent him a care package filled with cards, and around 100 other companies and collectors have also reached out to express their interest. The cause has even caught the attention of the major leagues. On April 21, Brady and Landen were invited to Fenway Park for a special ceremony hosted by the Red Sox.
