Manny Acta Out?

According to Fox’s Ken Rosenthal, Manny Acta is on the verge of receiving the axe and being forced to give up his managerial seat to bench coach Jim Riggleman. 
When it will happen is not clear, but his major league source says within several days. 
Acta has gone an awful 147-231 in his tenure with Washington, including a 15-42 start this season.
More to come later.
