"Greinke, two years ago, I don't know when we're going to see somebody match the kind of season he had, numbers-wise," Roenicke said. "That kind of season -- I don't want to say it's a fluke, because he's capable of doing that kind of thing -- but ... [Yovani] Gallardo has pitched pretty good for three years, and [Shaun] Marcum was their Opening Day starter in Toronto last year and he can pitch.
"I don't want to have people think that, hey, [Greinke] is our guy. Yeah, he is going to be definitely one of the leaders of the staff, but I don't think it's fair to put on him that, 'Hey, we've got a four-game losing streak and you have to be the guy that stops this.' Hopefully, we won't be in that situation too much."
Roenicke prefers the idea of pitchers pushing each other instead of one pulling the other four along.
"I think it's going to be a great competition for our pitchers," Roenicke said.
Greinke, acquired from the Royals in a December trade, will start against White Sox left-hander Mark Buehrle in Glendale, Ariz. The game will be webcast on Brewers.com and could be a matchup of Opening Day starters, though Roenicke still won't announce his plans for the regular-season rotation.
