The Nationals fire GM Mike Rizzo and manager Dave Martinez. @JeffPassan 1st.

Fitting that Miguel Cairo is named interim manager while the Nats are in St. Louis, a city where he was a well-respected infielder during two separate tenures. @MLBNetwork

The Nationals’ interim manager is likely to be promoted from within. Primary options include @MLB bench coach Miguel Cairo and Triple-A manager Matthew LeCroy. @MLBNetwork
