Second baseman Mark Bellhorn agreed to an $800,000, one-year deal with San Diego on Thursday, giving the Padres another member of the 2004 Boston Red Sox team that won the World Series. Bellhorn likely will replace Mark Loretta, who was traded to Boston this month for catcher Doug Mirabelli. Other candidates to play second base for the NL West champs are Josh Barfield and Bobby Hill. Also on the Padres from the 2004 Red Sox team is leadoff batter Dave Roberts, who will move from center field to left field to make room for Mike Cameron. Bellhorn lost his starting job last season and was released on Aug. 26 after declining an assignment to Triple-A. He was picked up off waivers by the New York Yankees. In 2004, he batted .264 with 17 homers and 82 RBI.
