Now, I'm no Cubs fan, far from it. But Chicago's Anthony Rizzo just did a pretty standup thing that I think all professional athletes can learn from.

Two-year-old Parker Hopkins was diagnosed with Acute Myeloid Leukemia about two weeks ago. Kiefer and Jordan Hopkins reached out to Rizzo after they received the devastating news about their son and the first baseman responded.

Rizzo sent the toddler a letter along with a $2,500 donation and some advice. Rizzo is a cancer survivor himself, he was diagnosed with Hodgkin's Lymphoma when he was eighteen.

He says in his letter, "I believe that by staying positive, I actually felt better and ultimately won my battle against cancer. I know that you too can do the same."

A GoFundMe campaign has been set up to help cover medical expenses for Parker. You can follow Parker's story on Facebook at Parker Strong.
