Derrek Lee, who agreed to a one-year deal last Thursday, sees a lot of positives in the rebuilding Orioles. "I think this team is confident," Lee said in an introductory conference call. "And I'm excited to be a part of that and maybe surprise some people." Baltimore has added third baseman Mark Reynolds and shortstop J.J. Hardy via trades. In addition, second baseman Brian Roberts is expected to be fully healthy after missing three-quarters of last season. "So far, so good," president of baseball operations Andy MacPhail said of the organization's position-player upgrades. "But the most important factor is going to be the continued health and maturation of our young arms."
