The Brewers may not have a definable ace in their starting rotation, but they are doing just fine this season. "I can't answer that," manager Ron Roenicke said when asked who leads Milwaukee's staff. The Brewers have three pitchers who started for clubs on 2010 Opening Day in Yovani Gallardo, Zack Greinke and Shaun Marcum. Randy Wolf is a capable No. 4. Plenty of teams, good teams, do worse than Chris Narveson as a No. 5. "Are we talking about No. 1 pitchers like Roy Halladay is a No. 1 pitcher?" Roenicke said. "We haven't had anybody have that long run that makes you say, 'Every time out there, he's had a great outing.'"
