According to Chico Harlan of the Washington Post, the Nationals have narrowed their search for a permanent GM to three executives, one of whom is making the calls as the club attempts to sign pitching phenom Stephen Strasburg. Acting GM Mike Rizzo, Red Sox assistant GM Jed Hoyer and D'Backs executive Jerry Dipoto are the frontrunners, but we shouldn't expect the Nats to name a permanent GM until after the deadline to sign draft picks passes on Monday.
