Dusty Baker is working to finalize an agreement to become manager of the Houston Astros, a person with knowledge of the negotiations told The Associated Press on Tuesday. Baker's hiring is a sign the AL champions want to bring an old-school mentality and stern presence to a franchise reeling from the dismissal of Hinch and general manager Jeff Luhnow. Baker has 22 years of managerial experience, starting in 1993 with the San Francisco Giants.
