Luhnow, team owner Jim Crane and president George Postolos met at length Monday at Union Station to discuss the options. Former Astros players Craig Biggio and Enos Cabell, who have been part of the interview process, were also in on the meeting.
"We are not at a point of conclusion yet but are getting closer," Luhnow said. "We started with a list of 45, we narrowed it down to a list of nine and we're down to a relatively small number now. We're not down to one yet, but we're getting closer. I do feel like the final group we're considering all have great future potential to be great managers in baseball, so we're excited about the choices we have in front of us."
The known candidates to have interviewed are Rays bench coach Dave Martinez, Red Sox bench coach Tim Bogar, Nationals third base coach Bo Porter and Astros interim manager Tony DeFrancesco. Former Astros catcher Brad Ausmus and former Phillies and Padres manager Larry Bowa have also interviewed but are no longer candidates.
Luhnow wouldn't say if the remaining finalists would be brought back for second interviews.
"We are hoping to move forward and we're excited, and hopefully we get to a successful conclusion relatively soon," he said.
