HOUSTON — The Astros fired manager Bo Porter on Monday, saying the dismissal had less to do with the team's 59-79 record than the need for "new direction" and a "united message throughout the entire organization."
Porter was in his second season with Houston and was succeeded by interim manager Tom Lawless, who worked in the Astros' minor-league system. Lawless' first game in charge is tonight at home against the first-place Angels.
Bench coach Dave Trembley also was let go.
Porter joined the Astros after working as a third-base coach for the Nationals. Houston went a franchise-worst 51-111 in his first season, their third straight 100-loss season.
General manager Jeff Luhnow said the decision was not based on "our current level of competitiveness." The Astros are in fourth place in the American League West and have the second-worst record in the league.
"I recognize that our win-loss record is largely a product of an organizational strategy for which I am responsible," Luhnow said in a statement. "Rather, I made this decision because I believe we need a new direction in our clubhouse."
Luhnow refused repeatedly to get into more detail about why Porter was let go as he fielded questions for almost 25 minutes.
DODGERS: CF Joc Pederson, one of the team's top prospects, was called up from Triple-A Albuquerque.
INDIANS: DH Jason Giambi, out since June 12 with soreness in his left knee, was activated from the 60-day disabled list to help the team's late playoff push.
MARINERS: 1B/DH Jesus Montero was put on the suspended list three days after he was involved in a verbal altercation with a team scout at a Class A Northwest League game.
MARLINS: RHP Henderson Alvarez left his start in the third inning with a strained left oblique and was listed as day to day.
REDS: The team plans to transfer RHP Homer Bailey to the 60-day disabled list today, ending his chances of pitching again this season. Bailey hurt his right elbow and went on the disabled list Aug. 16.
RED SOX: 2B Dustin Pedroia sat out a second straight game against the Rays because of concussion symptoms.
ROYALS: 1B Eric Hosmer, who fractured a bone in his right hand July 20 when he was hit by a pitch from then-Red Sox LHP Jon Lester, was activated from the 15-day disabled list. Also, LHP Brandon Finnegan, the team's first-round draft pick in June, was promoted from Double-A Northwest Arkansas.
