"Our starting pitching staff, because they haven't pitched like we thought, we're behind, 3-0, 5-0, and right off the bat, I'm looking at these thinking, 'I would like him to steal right here, but if he's thrown out, we're already down, 5-0, and I can't have him thrown out,'" Roenicke said. "So, I have put the red light on [Aoki] more this year -- a lot more -- than I did last year.
"Circumstances, the way we're playing, it doesn't allow us to have the freedom to run like I would like to run. I know I think we need it in our offense, to do those things. But we just can't afford to do that."
Even with those red lights, the Brewers entered Tuesday tied for second in the Majors with 62 stolen bases. But they are well behind their pace from 2012, when the Brewers led the Majors with 158 steals in 162 games.
One factor: Entering Tuesday's games, the Brewers were last in the Majors with 183 walks.
"That's been an issue, really, since I got here," Roenicke said. "Prince [Fielder] was a big walker, and that year , I think Ryan [Braun] had a lot of walks. Since then, we don't walk. It's just the team that you have, and you can't tell a guy, 'You need to walk.' What you hope to tell them is to swing at the pitch you want to swing at, not the one the pitcher wants you to swing at. Walks happen if you do it that way."
Roenicke actually praised two prospects for their strikeout-to-walk rates: Class A-Advanced Brevard County's Mitch Haniger and Class A Wisconsin's Tyrone Taylor.
