PHILADELPHIA -- The Houston Astros will name Bo Porter their new manager this morning, though the 40-year-old will finish out the season as the Nationals third base coach before officially taking over.
A club source confirmed the hiring, which was first reported early this morning by Foxsports.com.
Porter, who was in the coaching box at Citizens Bank Park for last night's Nationals victory, will be in Houston today for an 11 a.m. EDT news conference where he will be named the 21st manager in the Astros' 51-year history.
It's not yet known if Porter will be back in Philadelphia in time to coach tonight's series finale against the Phillies, but he will finish out the season with the Nationals in his current capacity before leaving for good.
A candidate for several managerial jobs over the last three years, Porter interviewed with the Astros two weeks ago. The Houston resident has no previous connection to the Astros organization, but he did know new owner Jim Crane prior to the interview.
Porter will face a stiff challenge guiding an Astros club that will finish with the majors' worst record this season and next year is relocating to an American League West division loaded with perennial playoff contenders in the Rangers, Angels and Athletics.
His departure erases any possibility of him replacing Davey Johnson once the 69-year-old Nationals manager decides to retire. Porter was considered a potential choice, along with bench coach Randy Knorr, who now becomes the in-house favorite to succeed Johnson, a move that's not expected to take place until 2014 at the earliest.
The Nationals will need to find a new third base coach to succeed Porter (who has held that job the last two seasons) next year. Tony Beasley, who managed at Class AAA Syracuse this season and served as Frank Robinson's third base coach in 2006, would probably be among those considered.
