Nationals third base coach Bo Porter has long been considered a potential big-league manager, so it's not surprising that multiple reports out of Houston say he's interviewing today for the Astros' job.
According to MLB.com and the Houston Chronicle, Porter flew to Houston today (an off-day for the Nationals) and is meeting with new Astros owner Jim Crane and general manager Jeff Luhnow.
Porter, 40, lives in Houston in the offseason, though he has no previous connection to the Astros organization. This isn't the first time he's interviewed for a major-league managing position, though: He was a finalist for the Pirates' job in 2010 and the Marlins' job in 2011 before ultimately losing out to Clint Hurdle and Ozzie Guillen, respectively.
Porter also was considered by the Nationals last fall, though Davey Johnson was widely expected all along to retain the managerial job after taking over in midseason.
Johnson has one year remaining on his three-year, consulting contract with the Nationals. He has said he won't discuss his situation until after the season, but he is expected to return for 2013 at age 70.
The Nationals, ideally, would like to eventually replace Johnson from within the organization, with Porter and bench coach Randy Knorr the most likely candidates to someday ascend to the managerial position.
In order to interview Porter while he's still under contract with the Nationals, the Astros would have had to receive permission from GM Mike Rizzo.
