Mets left-hander Johan Santana, who underwent Sept. 14 shoulder surgery to repair a torn anterior capsule in his left shoulder, has started tossing a baseball. New York pitching coach Dan Warthen said he spoke with Santana, who is rehabbing at his home in Fort Myers, Fla., by telephone. Santana is expected to arrive at the Mets' complex in Port St. Lucie within a couple of days, ahead of Tuesday's official reporting date.
