As expected, Pat Corrales will take over as the Nationals bench starting Friday, when the Nationals return home to play the Pirates. Corrales, 70, has been a front-office assistant with roughly the same duties as Davey Johnson had before moving into the manager’s role, roving around the minor league to evaluate and instruct.

“Now I’m not the older member of this club,” Johnson said.

Corrales served as the Nationals bench during 2007 and 2008 and also the second half of 2009. He managed three teams over a total of 10 years, his last season as a big league manager coming in 1987. He also played 10 seasons in the majors.

Johnson and Corrales became close during their advisory roles in the Nationals front office. In spring training, they would ride around on a golf cart together, roving the backfields. “If anybody tries to pick a fight with me, they’ll have to go through him,” Johnson said.
