The agent for shortstop Edgar Renteria said Wednesday that he's making significant progress toward a deal that would bring his client to the San Francisco Giants. "We're working on it and we're certainly much, much closer, but nothing is done," said agent Barry Meister. A source told ESPN.com that Renteria is looking at a contract in the two-year, $18 million range with San Francisco. WFAN radio in New York reported 10 days ago that Renteria had agreed to a deal with the Giants. But Meister had characterized that initial report as untrue.
