News from the Snooze... ] PITCHING IN: LHP Dave Williams joined the Mets and threw a bullpen session as pitching coach Rick Peterson observed. Williams is expected to be activated to start Sunday's game. He figures to take Sandy Alomar Jr.'s roster spot since Paul Lo Duca's two-game suspension will be completed tonight, making Alomar expendable. Williams, who had surgery on Jan. 31 to repair a herniated disk, said side-to-side mobility with his neck is slightly limited since the procedure. If either Oliver Perez (back) or Jorge Sosa (hamstring) is unable to take his first turn after the All-Star break, Williams could remain in the rotation. Otherwise, he figures to assume a long-relief role and jeopardize Aaron Sele's roster spot. Randolph suggested Perez is more likely to reenter the rotation immediately after the All-Star break. Perez lightly threw yesterday in Port St. Lucie, while Sosa has been throwing at 150 feet.
