Bo Porter was hired as Houston’s manager on Thursday, and the Astros hope he can help orchestrate a turnaround with this team similar to the one he’s been a part of in Washington.

Porter, who was the Nationals third-base coach this season, replaces Brad Mills, who was fired last month. Porter will remain with the postseason-bound Nationals for the rest of their season.

“I think he’s going to push us to get better, he’s going to push us to get better quickly, and he’s going to shorten the time that it takes for us to get to where we want to be as an organization,” General Manager Jeff Luhnow said.

Tony DeFrancesco has served as interim manager and will finish the season in that role.

Porter will lead the rebuilding effort of a young team that has the worst record in the majors, wrapping up its second straight 100-loss season. The Astros are in their first season under new owner Jim Crane and moving from the National League to the American League next year.

Tigers’ Scherzer to miss start

Detroit Tigers right-hander Max Scherzer will miss his start today because of a lingering problem with his throwing shoulder, leaving Detroit without one of its top pitchers in the middle of a close division race. Rookie Drew Smyly will start today.

Scherzer described the injury as a muscle strain. Scherzer (16-7) left his start against Oakland on Sept. 18 after two innings because of the injury.

Wilson to begin throwing Oct. 19

San Francisco Giants right-hander Brian Wilson is scheduled to throw Oct. 19 for the first time since Tommy John elbow surgery, and the always-confident closer insists he will be full strength by next spring training.

“I’d say that I’m way ahead of the game,” Wilson said on the field Thursday before a workout.

Wilson spent his third day on the field doing agility drills and light work.

McCutchen leaves game with injury

Andrew McCutchen bruised his left knee, came out of Pittsburgh’s loss Thursday and dropped out of the NL batting lead. McCutchen trapped a soft fly into short center by Daniel Murphy in the seventh inning and threw to second to force Ruben Tejada, who began the play on first base and wasn’t sure whether the ball was caught. McCutchen then was taken out of the game.
