Brewers starter Zack Greinke was honest this week when discussing the team's standing the National League Central. Milwaukee enters the weekend with a 6.5 game lead over St. Louis for first place. "It's definitely not locked up or anything, but if we continue playing well, it should happen," Greinke said. "It's on us, mainly. We've just got to keep doing as good as we're doing or close to that and make it as tough as possible on the other teams. It is ours to lose."
