Nationals third base coach Bo Porter to be named Astros manager

Nationals third base coach Bo Porter will be named the next manager of the Houston Astros on Thursday morning, but Porter will remain with the Nationals for the duration of their season and playoff run. The ensuing announcement, first reported by Ken Rosenthal of FoxSports.com, will not preclude Porter from staying with Washington this year.

The Nationals hired Porter prior to the 2011 season, and he has spent the last two years coaching third base, coordinating the Nationals’ running game and instructing outfielders. Porter, 40, had twice interviewed for a Nationals managerial vacancy – before the 2010 season, when the Nationals chose Jim Riggleman, and before this year, when Davey Johnson ultimately returned.

Porter interviewed with the Astros in Houston on Sept. 13. He would not have accepted any position that prevented him from finishing the Nationals’ run with Washington.

Porter lives in Houston in the offseason, but has not previously worked for the club. The Astros lost 108 games last season, and this year they are 50-105.

Porter had been viewed as a possible successor to Johnson when he steps down. Johnson appears likely to return next season, but whenever the time comes, General Manager Mike Rizzo has said he prefers to replace Johnson from within.

The leading current in-house potential successor to Johnson is now bench coach Randy Knorr, with first base coach Trent Jewett and minor league managers Tony Beasley, Matt LeCroy and Brian Daubauch also possible candidates down the road.
