The 30-year-old Mitre is 13-29 with a 5.27 ERA in seven seasons with the Cubs, Marlins and the Yankees. Mitre is 1-1 with a 5.73 ERA in 11 innings this spring training. Milwaukee will have to cover several starts while 2009 AL Cy Young Award winner Zack Greinke recovers from a broken rib.
The 28-year-old Dickerson was acquired by the Brewers in August last season for Jim Edmonds and had limited action in 25 games last year. He's hitting .278 with five RBIs in 17 games in spring training, but was expected to lose out for one of the last bench spots to Brandon Boggs and Jeremy Reed.
