DC GM Mike Rizzo will be online to answer your questions in a chat at the Nationals' official site starting at 12:00 noon today. You can submit questions ahead of time if you like, I already did, asking Mr. Rizzo why he was the only out-of-town GM at the Aroldis Chapman sessions, and wondering where he saw Roger Bernadina and Justin Maxwell starting the season...Check back later to see if he answered...
