Yankees pitching coach Larry Rothschild said the Japanese right-hander had a throwing session Tuesday in New York.

After a pre-spring training workout at Steinbrenner Field, said Rothschild said all the reports are good regarding Tanaka's rehabilitation program.

The Yankees said the injury dates from when Tanaka pitched in Japan.

He signed with New York before the 2014 season.
