Bogar is one of a few candidates for the position, including interim manager Tony DeFrancesco. Interest in Bogar comes in wake of former Padres and Phillies Manager Larry Bowa announcing he isn't interested in the job after being interviewed.
It's been reported the Astros have interviewed Tampa Bay bench coach Dave Martinez and Nationals third base coach Bo Porter, along with Bowa.
The Astros are one loss away from claiming their second consecutive 100-loss season. Former manager Brad Mills was fired Aug. 19 amid another disastrous season. Houston had the worst record in baseball (56-106) and could end 2012 in the same position.
