Last year the Brewers benefited from extraordinarily good health, particularly among their pitchers: They used just six starters, and their top five made all but seven starts. Given that their No. 7 starter was Sergio Mitre and their No. 8 may have been Bernie Brewer, a reliable rotation was a huge factor in the team's NL Central title. Milwaukee's depth has improved in the long term thanks to 2011 first-round picks Jed Bradley and Taylor Jungmann, both of whom should reach the majors late next season. In the short term, however, manager Ron Roenicke should bump his fifth starter, lefthander Chris Narveson, for a prospect expected to begin the season in the minors who not only has harder stuff but is also a better fit. Wily Peralta, 22, is a 6'2", 240-pound righthander who, in his sixth professional season, walked just 59 in 1502/3 innings between Double and Triple A. As a true strikeout pitcher (21.9% of batters faced in his minor league career), Peralta is also much more likely than Narveson to prevent the ball from reaching the Brewers' porous defense.
