Mills prefers the flexibility of carrying eight relievers, but he currently has seven arms in the bullpen because he's going with a six-man starting rotation until the All-Star break. Houston is currently carrying 12 position players, which is one less than most teams carry.
"What I liked was early in the season when we had a four-man rotation and could utilize the off-days," Mills said. "That way we had the extra reliever in the bullpen, plus we had a full complement of position players on the bench. If I had my druthers, that would be it."
The Astros will have 20 consecutive games without a day off after the All-Star break, which means Mills would like to have the extra bullpen arm. Steady reliever Wilton Lopez is expected to return from a sprained elbow after the break, but whether the Astros stick with the six-man rotation remains to be seen.
"We're going to talk about some things as we move forward, start talking about the rotations and so forth after the break," Mills said.
