Diamondbacks presenter has been arrested for DUI and the second DUI in two years. Clearly Mark has a problem with alcohol and we hope that he is now getting the treatment he needs to star this recovery. I love the way people condemn him but if he was sick with cancer they would all be upset and feeling sorry for him. Alcoholism is a serious a disease as cancer and often just as fatal. Sadly, unless you are an alcoholic its impossible to understand the complete recklessness which the alcoholic applies to their lives only because they are sick not bad.
