Miguel Rojas gladly gave up his No. 11 to Roki Sasaki and went back to 72, his jersey as a Los Angeles Dodgers rookie in 2014. Spring training workouts start Sunday with the Dodgers trying to become the first repeat champion since the New York Yankees won three in a row from 1998 to 2000. Coming off their second title in five seasons, the Dodgers added Sasaki, the prized 23-year-old right-hander from Japan, and left-hander Blake Snell to a pitching staff expecting two-way star Shohei Ohtani to return to the mound in April or May after recovering from elbow surgery.
