Nationals Tab Rizzo As GM

8:55pm: We can close the books on this one for now: Bill Ladson at MLB.com reports that Mike Rizzo will be named the permanent general manager of the Nationals at a news conference on Thursday. The decision was apparently made earlier this week, probably in the thick of the Strasburg negotiations.

Rizzo has made some pretty sage moves for the Nationals so far, and it looks like he's taking the beleaguered franchise in a good direction. It's unclear how long he's been signed for or why previous news had suggested the complete opposite.

8:16pm: This story looks more and more dubious as the hours pass. Chico Harlan at the Post reports that Rizzo was seen loose and joking with Nationals president Stan Kasten pre-game today, and he's currently scheduled for a Friday fan Q&A on the Strasburg signing. Harlan also says that Rizzo was the sole negotiator of the Strasburg deal in its final minutes and that, at this point, "[Rizzo's] stock has never been higher." When reached for comment, Rizzo was "mum" on the current situation, Bill Ladson at MLB.com says.

3:04pm: Jon Paul Morosi of FOX Sports hears that though the Nats have not yet decided on a permanent GM, they will decide on one this week. The team will introduce Stephen Strasburg at a Friday press conference, so an announcement before then would be a surprise.

2:53pm: A source tells Chico Harlan of the Washington Post that the reports saying the Nats have decided to replace Rizzo with DiPoto are false. 

"The decision has already been made," the source said. "And the best I can tell you- what's been written is 100% wrong."

The Nats have not told DiPoto or Red Sox exec Jed Hoyer of their decision, according to Harlan's source.

2:22pm: ESPN.com's Keith Law hears that the Nationals are not about to award Jerry DiPoto the GM job.

WEDNESDAY, 11:02am: Danny Knobler of CBS Sports reports that D'Backs exec Jerry DiPoto has told friends he will accept the Nats GM job.

TUESDAY, 9:43pm: According to Gordon Edes of Yahoo.com, "multiple sources insisted" today that the Nationals are about to replace interim GM Mike Rizzo with Diamondbacks vice president Jerry DiPoto. 

Rizzo has been busy since replacing Jim Bowden as GM earlier this year. He brought in Nyjer Morgan and fired Manny Acta. Most notably, perhaps, he has been given credit for engineering the signing of pitching phenom Stephen Strasburg.

DiPoto, who has been in charge of the Diamondbacks' pro scouting for four years, denied any knowledge that such a job change was imminent.
