“Principal Responsibilities” For Mike Rizzo

According to MLB.com’s Bill Ladson, Nationals assistant GM Mike Rizzo will take on "principal responsibilities when it comes to the Major League, Minor League, and scouting operations."  The Nats apparently don’t want to stick an interim GM tag on Rizzo, saying that president Stan Kasten remains in charge.  Ladson adds that the position vacated since former GM Jim Bowden resigned "will remain vacant for the foreseeable future."
