Rizzo writes letter, makes donation to young fan diagnosed with cancer

Anthony Rizzo continues to make as much of an impact off the field as he does on it.

After Rizzo heard about Parker Hopkins - a young boy who was recently diagnosed with acute myeloid leukemia, two months before his second birthday - the Chicago Cubs first baseman decided to take action.

Rizzo penned a letter to Parker describing his own personal battle with cancer, and made a $2,500 donation to help his family during a difficult time.
