Bench coach Joe Pettini, who joined the Astros prior this season after working for 10 seasons under Tony La Russa with the Cardinals, said he would like to remain on the staff.
"It was fun with this young club," he said. "It wasn't so much fun losing so many as we have, but it's always fun working with younger guys and seeing guys develop. Some guys turn into everyday players and some guys might not make it or stay here. That's the growing pains in the organization.
"Yeah, I would [like to stay]. I'm 57 years old and have 11 years as a coach at the big league level and a few as a player, and I'm not quite ready to retire yet. I'd like to do it a few more years."
Pitching coach Doug Brocail, 45, is in his first full season after taking over midway through the 2011 campaign for Brad Arnsberg. Since retiring as a player following the 2009 season, Brocail has remained in the organization in a variety of roles.
"Of course, I'd love to be back," he said. "I love this job, but we have a lot of work to do. I'd like to see it through. I don't know what their thoughts are. Nobody's talked about it, but if they want to sit down and talk, I'd love to be back. We all know we have a ton of work to do, we all know there's a plan in place, and that plan needs to be followed to a T, and I hope I'm the guy and they have confidence in me."
Third-base coach Dave Clark and bullpen coach Craig Bjornson were on the staff to start the season, while first-base coach Dan Radison and hitting coach Ty Van Burkleo took over in August. Radison knows Porter well, having spent time with him in Washington and with the Cubs.
"He'll be great," Radison said. "I was an advocate for him when they asked me early on. He's a great baseball mind and to me, even more than that. There's no phoniness about him. He's a straight-shooter, an honest guy, a high-character guy. I love the guy. I think he'll be great."
