Despite being very vocal about their front office operations in recent years, the Houston Astros have been tight-lipped about their managerial search.

Jeff Luhnow has said he may make a final round of managerial candidates available to the media, but nothing has been announced.

Ken Rosenthal of FOX Sports reported Wednesday that the Astros had spoken with five candidates: Dino Ebel, A.J. Hinch, Torey Lovullo, Dave Martinez and Don Wakamatsu.
