"When you play and you're batting, you go up and down," he said. "The defense, you have to have everything all the time. You have to make a routine play."
Astros third base coach Pat Listach, who handles infield defense, said he's proud of the defense of the entire infield, especially considering their struggles with the bats.
"I think for the most part, they haven't taken their at-bats to the field because we aren't hitting," Listach said. "If we're not hitting and not playing defense, now that's really bad. We will eventually hit, but the defense has to be there every day.
"You may hit four balls hard and not have any hits, but that's one of those things. The next day, three broken-bat hits fall. The defense has to be there every day. When the game's on the line in the ninth inning and two outs, I don't care which one of the infielders they hit it to. I'm comfortable with all of them, but there's always room for improvement."
