Baseball officials worked through the holiday weekend, and the action figures to pick up even more this week. The Red Sox could extend an offer to Billy Wagner as soon as Monday. Wagner, who already has offers from the Mets and Phillies in hand, could have interesting third and fourth options in the Red Sox and Braves. Bean Stringfellow, Wagner's agent, said yesterday that he expects to speak with both clubs early this week, although there are no face-to-face meetings planned with either team. The Braves, given their budget restraints, would have to rely on Charlottesville, Va., resident Wagner accepting a hometown discount of sorts. But the Red Sox, whose closer, Keith Foulke, had an injury-filled 2005, certainly can match the Mets when it comes to financial firepower. They signed Foulke to a four-year deal (for $24 million) two offseasons ago, so they have established a precedent of committing four years to a closer.
