"The whole situation has been good," Mills said. "Terry has been great. It's a fun coaching staff to be with, and [hitting coach] Ty [Van Burkleo] has done a great job with these guys. It's a good group, especially to be able to come together like they have and play for something at the end."
Mills went 171-274 in his nearly three years at the helm of the Astros, who were slowly dismantled shortly after he took over. The roster turnover hasn't stopped, and there are very few players remaining from Mills' time in Houston.
"I look at [Jose] Altuve and how he's doing and Brandon Barnes, who was there very little with me," Mills said. "Guys like Marwin Gonzalez, Carlos Corporan and Brett Wallace you follow because you were with those guys for almost three years. I care about these guys and they're good people."
