On the Yankees or Red Sox, Kevin Millwood would make a nice No. 4 starter. On the Orioles, he is a far bigger deal. His acquisition is supposed to give Marylanders hope that their team finally is gaining ground on the division monsters. In reality, Baltimore will be fortunate if the righthander proves to be a top-of-the-rotation innings-eater able to show an up-and-coming staff how it is done. At worst, Millwood should provide an upgrade to a rotation that tied the Brewers for the worst ERA (5.37) in the majors.The Orioles also improved their bullpen by signing closer Mike Gonzalez The only change they have made so far to their lineup is at third base, where Garrett Atkins, nontendered by Colorado, will replace Melvin Mora (unless Atkins moves to first base).
