Colorado Rockies manager Jim Tracy resigned Sunday, stepping down after the team set a franchise record for losses while finishing last in the NL West at 64-98. Tracy was promoted from bench coach to manager in May 2009, and was voted NL Manager of the Year that season after guiding Colorado to the playoffs. ‘‘I was surprised,’’ said Bill Geivett, the team’s director of major league operations. ‘‘I wanted Jim to come back. That’s how we began our conversation on Friday, that he was the manager. But he called and informed me today he was resigning.’’
