The Astros have announced that Brad Mills, first base coach Bobby Meacham, and hitting coach Mike Barnett have all been released from their duties. Interim replacements will be announced tomorrow morning.
Pure speculation on my part is that current bench coach Joe Pettini, who was brought over by Luhnow after serving as Tony LaRussa's bench coach for several years in St. Louis, will be named head coach on an interim basis and will get every opportunity to secure the position long term.
More to come.
