Gunnar Sandberg, the Marin Catholic High School pitcher who was hit in the head by a line drive March 11, left Marin General Hospital on this week and checked into a rehabilitation hospital in San Francisco.

From watching movies with his family to taking walks with nurses, the 16-year-old Kentfield resident has had continued progress since emerging from the coma he was placed in on March 12, the family wrote on a Web page dedicated to Sandberg's recovery.

''Gunnar's transfer to the rehabilitation hospital this afternoon went great," Bjorn Sandberg, Gunnar's father, said in an e-mail. "He and Lisa (Gunnar's mother) have just settled in for the night. In the past couple of days he's made great strides . . . beginning to communicate with us."

Sandberg still isn't speaking, but he is "paying attention and starting to follow commands," his father said.
