HOUSTON -- Dave Trembley, the former Orioles manager who spent last season as the Astros' third-base coach, said Wednesday he accepted an offer to return to the coaching staff for 2014 in a role that will be announced later.
The decision comes one day after the Astros parted ways with first-base coach Dave Clark and bullpen coach Dennis Martinez, and reassigned pitching coach Doug Brocail, who will be a special assistant to general manager Jeff Luhnow and a senior pitching advisor.
Astros manager Bo Porter, who brought Trembley to Houston, played for three Minor League teams that Trembley managed.
"I'm confident in the opportunity to show significant improvement for the 2014 season," Trembley said. "There's some acquisitions that are needed, and I know Jeff and Bo are working on acquiring that and identifying what those needs are.
"I'm certainly excited a lot of the young players did so well at a high level of the Minor Leagues and will have an opportunity to make the club. I love working with young players. Houston is a very good baseball city, the facility is one of the best in the game, and we have to start showing some improvement next year."
Trembley, 61, spent the 2011-12 seasons as the Minor League field coordinator for the Atlanta Braves. Trembley has been in professional baseball the last 29 years, including 20 years as a Minor League manager with Pittsburgh (1987-89), San Diego (1991-93), Chicago Cubs (1995-2002) and Baltimore (2003-06).
Trembley spent three years as the manager of the Orioles, taking over in June 2007, when Sam Perlozzo was dismissed, but was let go midway through '10. The Orioles went 187-283 during Trembley's tenure.
Luhnow said Tuesday that Eduardo Perez, the bench coach last season, was offered a contract to return. Hitting coach John Mallee is coming back for 2014.
