The Orioles head into Christmas Week without a closer, but they are still in the mix for free-agent right-hander Fernando Rodney. According to an industry source, the Orioles are one of four teams who have shown “significant interest” in the 36-year-old, who saved 85 of 95 opportunities for the Tampa Bay Rays in the past two years. The Orioles had pursued Rodney earlier this offseason, but ultimately turned their attention to Grant Balfour, who agreed to a two-year, $15 million deal with the team last week before the Orioles backed out citing medical concerns after reviewing Balfour’s physical. Since that announcement became official Friday, the intensity of Rodney’s market has unquestionably increased, the source said. Because of his experience in the American League East, the Orioles are more interested in Rodney than any other free-agent closer, but the question is whether the club would be willing to offer a deal beyond what they nearly gave Balfour. The sense is it still may take more than two years and $15 million to get Rodney -- and that may be beyond the Orioles' comfort level.
