The Astros also dismissed bench coach Dave Trembley after the team posted a 59-79 win-loss record. Adam Everett will replace Trembley while the search for the Astros' new manager begins immediately, notes MLB.com's Brian McTaggart:
"Astros manager Bo Porter and bench coach Dave Trembley were relieved of their duties on Monday, the team announced. Tom Lawless was named interim manager through the remainder of the 2014 season.
"Porter had been the Astros' manager since the start of the 2013 season after being named to the position on Sept. 27, 2012, while he served as third-base coach for the Washington Nationals. Adam Everett will join Houston's coaching staff, replacing Trembley as bench coach. The remaining coaches will continue in their current roles.
"The Astros' search for a new manager will begin immediately, the team said in a statement.
"The Astros entered Monday with a 59-79 record in Porter's second full season as manager, having already surpassed their win total from each of their previous three seasons. At 42 years old, Porter was the youngest manager of baseball's youngest team, which has been undergoing a massive rebuilding operation in recent years.
"'Bo's passion and energy are unparalleled, and his desire to win unquestioned,' Astros general manager Jeff Luhnow said in a statement. 'This decision was not made because of our current level of competitiveness in the Major Leagues. I recognize that our win-loss record is largely a product of an organizational strategy for which I am responsible. Rather, I made this decision because I believe we need a new direction in our clubhouse.
"'What we will seek going forward is a consistent and united message throughout the entire organization. It is essential that as an organization we create an atmosphere at the Major League level where our young players can come up and continue to develop and succeed. Ultimately, I am responsible for creating that culture, and I will do everything in my power to do so -- even when it means making difficult moves like the one we made today.
"'Moving forward, I am optimistic about the direction of our team. Our young core continues to progress, and I believe wholeheartedly that our plan -- while at times challenging -- is working and will bring a consistent winner to Houston in the very near future.
"'We wish Bo and his family well, and feel he will be successful in future endeavors."

For his part, Porter released his own statement on his dismissal, per The Houston Chronicle's Nick Mathews:
"I want to thank the Astros organization for giving me my first opportunity to manage Major League Baseball.
"During my time in Houston I dedicated myself to do everything I could to help this organization win, in the short term and for the long term.
"I am proud of what we were able to accomplish in Houston with an organization in transition. I'm gratified we were able to bring some excitement to this city as a result of our improvement from 2013 to 2014.
"I am enthusiastic about what the future will bring for me and my family. I look forward to my next opportunity in Major League Baseball. The valuable experience I gained with the Astros will be extremely beneficial in all my future endeavors.
"I want to especially thank my players, my staff and support staff for all their efforts in our attempt to develop a championship culture doing my time as manager of the Houston Astros.
"I want to thank the baseball community for your kind words and the countless text messages, phone calls, voicemails and emails. Your support is what makes our game and industry so great!
"Last but surely not least I want to thank the city of Houston and the fans for the incredible support they have shown towards me and my family during our time in Houston.
"I wish the Astros well in the future and look froward to the next chapter of my baseball career."
According to Baseball-Reference.com, Porter has a cumulative win-loss record of 110-190 (.367) in two seasons with the Astros.
